The Wormhole Prints Rocket Barrels Next to Thrust Stands That Simulate Mars Transfer — and NASA Is Betting 2028 on Both

How the NASA Aeolus Win Rewired Relativity's Talent Strategy

On June 17, 2026, NASA Administrator Jared Isaacman stood in front of a cylindrical gray spacecraft at Relativity Space's Long Beach facility and announced something the company had never had before: a deep-space mission contract. Under a six-year reimbursable Space Act Agreement (NASA's first), the agency selected Relativity to design, build, and fly the Aeolus Mars orbiter, carrying four atmospheric-science instruments to the Red Planet in 2028. NASA supplies the payload and data pipeline. Relativity supplies the spacecraft, the Terran R launch vehicle, and cruise operations.

The structure gives commercial partners predictable development timelines rather than the annual appropriations roller coaster. For Relativity, it is something more consequential: institutional validation from the most demanding customer in the space sector, at a moment when the company has never placed a payload in orbit.

That gap matters. Terran 1 flew once, in March 2023, and failed to reach orbit after an issue about three minutes into the mission. The company shelved the vehicle and pivoted to Terran R, a medium-lift reusable rocket whose first flight has slipped from late 2026 into 2027, according to industry sources cited by SpaceNews. Terran R has not flown. The Aeolus spacecraft has not been built. The 2028 launch window gives Relativity roughly two years to finish both.

NASA is betting that the model — agency instruments riding commercial buses — can compress what used to be a decade-long procurement cycle into a single launch window. "Public-private partnerships like this are a force multiplier for science," Isaacman said in the agency's announcement. The Aeolus instrument suite, built at NASA's Ames Research Center, includes a Doppler wind and temperature sounder (a collaboration with GATS), a thermal limb sounder (a collaboration with Xiomas Technologies), surface radiometric sensors, and a wide-field context camera. Together they aim to produce the first daily, global picture of Martian winds, temperatures, dust, and clouds, data NASA says is essential for planning crewed landings.

The contract also anchors Relativity's new Interplanetary Sciences Program, a commercial lane for planetary missions that CEO Eric Schmidt has framed as the natural extension of Terran R's scale. SpaceNews reported that the orbiter will double as a communications relay for surface assets and carry proprietary compute infrastructure designed to run AI workloads in Mars orbit. An undisclosed philanthropic organization is funding the mission, according to a source familiar with the company's plans. Neither NASA nor Relativity disclosed the contract value.

What the win does, immediately, is change who Relativity can hire and what it can promise them. Before Aeolus, the company was selling prospective engineers on a reusable-rocket bet with an unproven vehicle and a 2023 failure on the record. After Aeolus, it can point to a NASA deep-space mission on the manifest — a line on a resume that competes with anything at SpaceX or Blue Origin. The company's Long Beach careers page already emphasizes "interplanetary exploration" alongside reusable rockets and advanced manufacturing. Now there is a specific mission behind that language.

Building an interplanetary spacecraft demands mission assurance engineers, autonomous flight software developers, and large-scale additive manufacturing specialists, the kind of roles Relativity's Stargate 3D-printing platform was designed to support but that now need to operate under deep-space reliability requirements. The Aeolus contract converts those roles from theoretical to urgent.

Whether Relativity can close the gap between where it is and where Aeolus requires it to be is an open question. The company must finalize Terran R, design and integrate an interplanetary spacecraft, and execute a Mars transfer, all before the 2028 window closes. NASA's track record with startup partners is mixed; some have gone bankrupt before delivering, and at least one Moon lander tipped over on arrival. But the agency has clearly decided that lower cost and faster timelines are worth the risk, and that the commercial deep-space logistics market needs a proof point.

Aeolus is that proof point, if Relativity can make the run.

What 200 Open Roles Say About Building a 3D-Printed Mars Rocket

The Aeolus contract didn't just hand Relativity a science mission; it forced the company to define, in job postings, exactly what kind of engineer builds a 3D-printed rocket that NASA trusts to reach Mars. The answer is visible in the open positions on the company's careers page and aggregated job boards, a cluster of which point to a workforce that looks nothing like a traditional launch provider's.

Start with the additive manufacturing roles. A listing for a Senior Additive Manufacturing Engineer (one of at least 23 additive-focused positions on Glassdoor) asks for hands-on experience with laser powder bed fusion, the process at the heart of Relativity's Stargate printers. The job calls for someone who can develop process parameters across multiple alloy systems, own the full manufacturing pipeline from design-for-additive through post-processing, and run root-cause analyses on material failures. The salary range sits between $112,000 and $143,000 in Long Beach, with equity on top, per the General Catalyst job board listing. That's not a role you'd find at a company that outsources its structures. It's a role for someone who treats the printer as the product.

The posting also reveals how tightly Relativity links its manufacturing work to propulsion hardware. The Additive Development team, per the listing, produces components for Aeon-1 and the upcoming Aeon-R engines. The engineer who fills this job won't be printing brackets; they'll be printing parts that go inside liquid-propellant rocket engines, where a porosity defect or a grain-structure anomaly means a test stand failure or worse. The listing's "nice to haves" include familiarity with liquid-propellant engine systems and statistical data analysis in JMP or Minitab, tools more common in metallurgy labs than in aerospace procurement offices.

Then there's the flight software side. LinkedIn postings show Relativity hiring a Senior Flight Software Engineer and a Senior Software Engineer for flight software, both in Long Beach. These roles sit at the intersection of autonomous flight termination (the system that destroys a rocket if it veers off course) and the broader software-defined manufacturing stack that Relativity has built around Stargate. The company's pitch on its own careers page frames the mission as "building the next great commercial launch company" alongside "becoming America's leading force in additive manufacturing innovation." The flight software roles are where those two ambitions meet: the rocket has to fly itself, terminate itself if needed, and do so with hardware that was printed, not machined.

What's missing from the postings is just as telling. There's little of the traditional aerospace role taxonomy, separate structures, propulsion, avionics, and GNC silos with decades of institutional process behind them. Instead, the additive roles ask for CAD, GD&T, and design-for-additive fluency in the same breath as manufacturing execution systems and quality management. The company wants engineers who can move between a build-file program and a root-cause investigation without switching teams.

A Mars orbiter can't be patched after launch. Every printed component has to meet deep-space mission assurance standards, and the people qualifying those components need to understand both the physics of powder-bed fusion and the documentation rigor of NASA's review process. Relativity's job postings aren't just filling seats; they're specifying the exact hybrid skill set that makes a 3D-printed Mars mission plausible.

Inside "The Wormhole": America's First 3D-Printed Rocket Factory

Relativity Space's Long Beach headquarters, a one-million-square-foot facility the company calls "The Wormhole," is where the company's entire manufacturing thesis gets stress-tested daily. Every Terran R primary structure starts here, from raw material through full-scale barrel assemblies and stage integrations. Aeon R and Aeon V engines are built on-site using powder-bed fusion printers and CNC machining systems. The layout is designed for a seamless flow from design and build to shipment for testing and launch operations, a deliberate choice to keep iteration cycles tight.

As of August 2025, all eight first-stage barrels and both second-stage barrels for Terran R's inaugural flight were complete, welded on the company's vertical friction stir welder. The first circumferential friction stir weld, joining two fuel barrels together, was finished, and first-stage tank welding had commenced. The paint booth came online that same month, and the first flight engine was shipped to NASA Stennis for acceptance testing, per Relativity's August 2025 company update.

What makes the Long Beach site unusual is the co-location of production and testing infrastructure that most competitors keep in separate states. The structural test stand activated in August can withstand up to 6 million pounds of compression, 170,000 pounds of shear, and pressures up to 250 psig. After activation, the thrust structure was installed and underwent multi-week acceptance testing, including a flight case simulating maximum dynamic pressure. The company is preparing for a hold-down case replicating launch pad conditions. A cryogenic test yard, vibration stations, and thermal-vacuum chambers round out the in-house capabilities, letting Terran R components undergo rigorous testing before being shipped for integrated stage and vehicle work.

Adjacent to The Wormhole is The Portal, Relativity's additive manufacturing R&D center. This facility houses multiple Stargate printers, the company's proprietary large-format metal 3D-printing platform, along with advanced robotics labs, quality labs, and test stands. The Portal brings together data sciences, robotics, material sciences, weld development, and simulation teams under one roof. It is where the company's core bet, that a rocket can be printed with far fewer parts than a traditional vehicle, gets refined from concept to production hardware.

The May 2025 production update posted on Relativity's LinkedIn page showed the pace accelerating: automated drilling processed thousands of holes on thrust structure panels, the LOX dome was loaded onto the circumferential friction stir welder, and stage-two transfer tube welding was underway. A newly installed vertical turning lathe was ready for multi-axis dome machining, and a horizontal friction stir welder, dedicated to lap-welding structural stringers on first-stage panels, was being installed. Two automated phased array ultrasonic testing systems were operational or being installed for weld inspection, a critical quality gate for flight hardware.

This physical infrastructure is the anchor for the hiring blitz. The roles Relativity is trying to fill, manufacturing engineers, avionics system integration and test engineers, thermal engineers, structures test engineers, map directly onto the production capabilities coming online in Long Beach. The company brought on Robin Petitprez as SVP of Manufacturing and Supply Chain to lead the scaling effort, a signal that the build phase has moved from development into industrialization.

The Long Beach campus is also where Relativity absorbed the lessons of Terran 1. That rocket flew in 2023 as the world's most 3D-printed vehicle, validating the Stargate platform across large-format metal deposition, in-process inspection, and autonomous robotic control. The flight, and the data from its failure to reach orbit, informed the design and manufacturing changes now being executed on Terran R in the same facility. The factory is not just building a rocket. It is the institutional memory of the company, encoded in tooling, test stands, and the teams that run them.

Can Relativity Compete With SpaceX and Blue Origin for Engineers?

Relativity's Long Beach campus sits in the middle of the most concentrated aerospace hiring corridor in the country. SpaceX's Hawthorne headquarters is a 20-minute drive north. Rocket Lab runs propulsion design and spacecraft assembly out of its own Long Beach facility. Blue Origin's Kent, Washington operation is more remote but competes for the same national talent pool. The Aeolus win gives Relativity a recruiting story its rivals can't match right now, a NASA deep-space mission on the books, but the company still has to close candidates against employers with longer flight histories and, in SpaceX's case, a war-chest hiring engine.

The salary data tells a mixed story. Levels.fyi's figures put Relativity's median total compensation at $139,300. A senior software engineer can pull $187,000 in base total comp; a staff-level engineer tops out around $217,000. Mechanical engineers land between $104,000 and $130,000 depending on level. Those numbers are competitive with what Rocket Lab posts for its Long Beach propulsion roles (Rocket Lab's board shows a Senior Propulsion Systems Engineer I/II at $132,000–$176,000), but they sit below SpaceX's known bands for equivalent roles, where senior engineers in Hawthorne routinely clear $200,000 all-in.

Where Relativity fights back is equity. The company offers two vesting schedules: a standard 25% per year over four years, or an alternate front-loaded plan that vests 10%/20%/30%/40%, per Levels.fyi. For a pre-IPO company betting that Terran R and the Aeolus contract will drive valuation, that equity upside is the pitch. SpaceX offers equity too, but its last secondary pricing rounds have been relatively stable, so the explosive upside case is harder to make. Blue Origin's comp is the most conservative of the three larger competitors.

Hiring velocity is where the gap widens. Zero G Talent's board shows SpaceX added 118 roles in the past seven days across its Texas, Florida, Washington, and California sites. Blue Origin added 124, though most are concentrated in Kent and Florida's Space Coast, not Southern California. Rocket Lab added 43. Relativity's own careers page doesn't publish a rolling count, but the breadth of roles tied to the Aeolus mission, additive manufacturing, autonomous flight termination, mission assurance, suggests a targeted expansion rather than the blunt-volume approach SpaceX runs.

The role types reveal different strategies. SpaceX's latest postings include an Executive Sous Chef at Starbase and a Manager, Hospitality, because the company is building a company town and hiring for it. Blue Origin's board skews toward quality engineering and operations finance, consistent with a production-scale-up phase for New Glenn. Rocket Lab's Long Beach listings mix propulsion hardware with security-cleared roles like a Personnel Security Lead, reflecting its growing government and defense work. Relativity's open positions cluster around the intersection of large-scale metal 3D printing and flight software, a narrower, more specialized band that's harder to recruit for but also less directly competitive with SpaceX's generalist aerospace roles.

For an engineer choosing between the four, the calculus comes down to risk tolerance and domain interest. SpaceX pays the most cash and offers the most flight heritage. Blue Origin offers stability and a clear path to New Glenn production. Rocket Lab gives you small-launch flight rate and a growing spacecraft business. Relativity is selling the Mars mission, the 3D-printing thesis, and equity in a company that's never flown an orbital rocket. The Aeolus contract doesn't close that gap, but it narrows it, and in a hiring market where candidates have options, narrowing the gap is the win.

From Terran 1's Failure to Mars: The Engineering Culture Shift Behind the Hiring

On March 23, 2023, Terran 1 lifted off from Cape Canaveral's LC-16 at 03:25 UTC. The 110-foot rocket, 85% 3D-printed by mass, survived Max-Q, the moment of highest structural stress, and executed a clean first-stage separation. Then, roughly three minutes in, the second stage's AeonVac engine failed to reach full power. A slower-than-expected valve opening and a suspected vapor bubble in the liquid oxygen turbopump killed the mission. The rocket never reached orbit.

Relativity called it a win. CEO Tim Ellis tweeted that the flight "proved Relativity's 3D-printed rocket technologies that will enable our next vehicle, Terran R," calling it "the biggest proof point for our novel additive manufacturing approach." During the launch webcast, company representative Arwa Tizani Kelly said the team had gathered "enough data to show that flying 3D-printed rockets is viable."

The rhetoric was confident, but the failure forced a concrete decision. Within weeks, Relativity announced it was going "all in" on Terran R, effectively shelving Terran 1 after a single flight. Ellis told CNBC the company was "putting all energy and resources on getting Terran R to market as quickly as possible." Existing Terran 1 customers were migrated to Terran R. A NASA Venture Class Launch Services contract for three CubeSats, booked for Terran 1's second flight, was among the canceled missions.

That pivot reshaped what Relativity hires for now. Before Terran 1, the company's identity was built on a single audacious claim: that additive manufacturing could produce an orbital rocket faster and cheaper than traditional methods. The hiring profile reflected that: materials scientists, large-scale metal 3D-printing engineers, and process automation specialists dominated the roster. Terran 1's flight proved the structures worked under real aerodynamic loads. It also exposed the gap between surviving Max-Q and running a reliable deep-space mission.

The NASA Aeolus contract, awarded for a 2028 launch, demands that gap be closed. Building a rocket that can reach orbit is one thing. Integrating a spacecraft bus, managing payload interfaces, and guaranteeing mission assurance for a multi-year transit to Mars is another. Relativity's current job listings reflect the shift: roles like Spacecraft Systems Responsible Engineer within an Interplanetary Program, a position that didn't exist when the company was focused on Terran 1, now sit alongside the additive manufacturing posts that defined its early hiring.

Ellis has framed the Terran 1 data as foundational. "I think there's a strong argument that we proved more than any other company has in that first flight," he told CNBC in April 2023. The preliminary failure analysis gave the engineering team specific, actionable fixes, valve response times and turbopump inlet conditions, rather than a wholesale redesign. Terran R inherits the methalox propellant choice, the Aeon engine family's architecture, and the software and ground infrastructure validated during Terran 1's launch campaign.

But the hiring blitz triggered by the Aeolus contract isn't just about scaling what Terran 1 proved. It's about building the systems engineering and mission integration muscle that a deep-space science contract requires, the kind of work where failure analysis feeds directly into reliability modeling, where autonomous flight termination has to account for communication delays measured in minutes, and where the manufacturing team has to produce hardware that works not once on a test stand but repeatedly across a production run.

Terran 1 taught Relativity that 3D-printed structures can survive flight. The Mars orbiter contract is teaching it what comes after survival.

Why Eric Schmidt's Takeover Signals a Software-First Rocket Company

Eric Schmidt didn't just write a check. He took the wheel. In late 2025, the former Google CEO acquired a controlling stake in Relativity Space and stepped in as CEO, injecting nearly $800 million into a company that had burned through over $1 billion in losses and was struggling to raise capital, Bloomberg and Theia reported. The move signals something larger than a financial rescue: it reframes Relativity as a software-defined manufacturer in an industry still dominated by hardware-first thinking.

Schmidt's track record is the point. He ran Google from 2001 to 2011, then served as executive chairman of Alphabet until 2019. His investment thesis has consistently favored companies where software and AI-driven automation reshape physical industries. Relativity's pitch, that its Stargate 3D printers and autonomous flight software can compress rocket production timelines and reduce part counts, fits that thesis precisely. Bloomberg reported that Schmidt's backing arrived after Relativity's 2024 fundraising efforts faltered, with Fidelity marking down the company's valuation. His involvement is as much a credibility signal to other investors as it is a cash infusion.

The hiring reflects this orientation. Relativity's open roles include a Senior Software Engineer, Full Stack, whose team is building what the job post calls "a modular, scalable software platform that can power highly autonomous operations on Earth and beyond." The language is deliberate. This isn't a company bolting software onto a manufacturing process; it's treating the software layer as the backbone. Talk of Titusville noted that Schmidt's approach "aligns with Relativity Space's core philosophy of utilizing AI-driven automation and additive manufacturing to revolutionize spaceflight."

That distinction matters for anyone considering a role there. Traditional aerospace employers organize around mechanical and systems engineering hierarchies. Relativity, under Schmidt, is structuring around software-defined manufacturing: printers that iterate faster than tooling shops, flight termination systems that run on autonomous logic, and a production floor where the code base is as critical as the weld. The company's fourth-generation Stargate printer, which builds horizontally and can produce structures up to 120 feet long, is as much a software product as a hardware one.

The risk is that Schmidt's software-first lens meets the unforgiving physics of orbital launch. Terran 1 failed to reach orbit in March 2023, and the pivot to Terran R, a partially reusable medium-lift vehicle targeting a 2027 first flight, is the company's last clear shot. The $800 million gives Relativity runway, but the Aeolus Mars orbiter contract is what gives it a mission beyond simply surviving. For engineers deciding between a role at Relativity and a competitor down the road in Hawthorne or Kent, the question isn't just compensation. It's whether you want to build rockets the way a software company builds products, or the way traditional aerospace builds aircraft.
