Working at Vast: Culture, Pace and Who Thrives

How Work Gets Done: Pace, Structure, and Engineering Culture

The first U.S. space station structure in two decades didn't arrive on a traditional aerospace timeline. It arrived because a team in Long Beach built three major structures in twenty-four months, tested each one to flight standard before the next weld, and treated every ground simulation as a dress rehearsal for orbit.

Vast compresses what legacy programs stretch across years into quarters, operates with a flat, function-heavy org where technical leads own end-to-end subsystems, and selects for engineers who can iterate rapidly from test failure to design change. This piece maps how that pace shapes daily work, what the company's seven operating principles look like in practice, what the interview actually tests, how compensation aligns with the asymmetric bet on Haven-1, and who thrives — or burns out, inside the tempo.

The Haven-1 primary structure qualification article — completed October 2025 after pressure and load acceptance testing in Mojave, was the third major structure finished in two years. Manufacturing began November 2023 not just to produce flight hardware but to establish the tooling, team, and processes that carry through to Haven-1 and, ultimately, Haven-2. The same people who qualified the structure build the flight article, and the ones after that. Institutional memory stays on the floor.

Velocity in the org chart

The headcount tells the story. Vast's careers page cites 1,000-plus experts (according to Vast's careers page); Zero G Talent's board shows six active director requisitions — Fluid Systems Test, Sub Assemblies Manufacturing, Mission Assurance, Satellite Engineering, Mission Engineering & Management, and Loads & Dynamics. That spread, six director openings in parallel, signals this model rather than feeding requirements up a chain. In July 2026 the company formalized a Special Programs Division under Melanie Stricklan, former CEO of Slingshot Aerospace and a U.S. Air Force veteran, adding a dedicated lane for national-security work without derailing the core station schedule. Steve Isakowitz, former president and CEO of The Aerospace Corporation and a NASA executive, joined as an advisor the same month — external gravitas plugged directly into the technical baseline.

Simulate, then build

"Simulating station operations on the ground ahead of flight is fundamental to how we build hardware for Haven-1," the company states, and the test record backs it. Before welding the Thermal Pump Tray assembly for flight, the team ran a development simulator to verify the welding approach was repeatable, reliable, and safe. Haven Demo, the on-orbit testbed for critical Haven-1 systems, moved through electromagnetic compatibility testing, thermal-vacuum chamber runs, and vibration testing at the Long Beach headquarters before deploying on the Bandwagon-4 rideshare in November 2025. It achieved mission success, captured 4K video of solar array deployment, and reached power-positive status before deorbiting in February 2026. Parallel campaigns ran at NASA Marshall for the trace containment control system (validating toxic-pollutant removal), in Mojave for pressure and load acceptance on the primary structure including hatch and domed window, and on the Power Distribution Unit, ventilation fans, and the MMOD shield covering the entire station. Each test fixture, window kick tests simulating hundreds of pounds of force, fan runs circulating fresh air and cooling payloads, is designed to catch failure modes on the ground where iteration is cheap.

Manufacturing as a control lever

Vast brings station manufacturing in house, a deliberate counter to the subcontractor-heavy model that adds latency and dilutes ownership. The primary structure, hatch, and domed window are fabricated and tested on the same campus where the engineers sit. The partnership with SpaceX — Haven-1 launches on a Falcon 9, extends the same logic to the launch vehicle: a proven, high-cadence rocket removes a variable the company doesn't need to invent.

The tempo filter

The stated operating rhythm — "ambitious timeline," "rapid progress amid high uncertainty," "extreme ownership", is not aspirational. It is the condition for winning the next phase of NASA's Commercial Low Earth Orbit Destinations program and hitting a Haven-1 launch target of 2027 (with an internal compilation showing hardware progress toward a May 2026 target). The pace selects for that profile. The next section examines how the company's stated values and operating principles show up in that daily rhythm, and where the gap between poster and practice actually lives.

Seven principles, one operating system

Vast publishes seven operating principles on its careers page — All in, Committed to safety and reliability, Making it happen, Respect, Action, Curiosity, Excellence, and the research shows each one showing up in how the company actually behaves. The principles are not posters on a wall; they are the logic behind the vertical integration model, the two-year hardware cadence, and the design choices that distinguish Haven-1 from the International Space Station.

All in reads like a description of the SpaceX playbook Vast has adopted: "bottom-up engineering and first principles-led approach where we are empowered to make decisions, own the outcomes, and collaborate." A Bloomberg Live interview with the lead astronaut, who joined in December 2023, makes that concrete. When they arrived, the company was still trading stainless steel versus aluminum for the primary structure. Less than two years later, the flight module sits fully assembled in Long Beach, the primary structure complete, secondary structures and integration underway. That speed only exists because design, engineering, and manufacturing share one roof, a deliberate choice the same speaker calls out: "having everything under one roof, we have control over our supply chain… allows us to pivot, to react quickly and actually tailor our hardware to exactly what our needs are."

Making it happen — the operating rhythm described above, plus the ethos "we work hard, we deliver, and we win and celebrate together," maps directly to the Haven Demo mission. The demonstration satellite, loaded on a Falcon 9 at the Cape as of the November 2025 interview, was built to test propulsion, guidance and navigation, and Vast's home-built computers in orbit before the crewed flight. The qualification article pathfinder, the primary structure unit, the hatch installation, each milestone posted to the company's own updates page with dates and photos, forms a public commitment log competitors have not matched. Eric Berger, writing for Ars Technica, singled out the in-house manufacturing advantage; Gwynne Shotwell of SpaceX publicly endorsed the partnership. The timeline is not aspirational; it is instrumented.

Committed to safety and reliability appears in the testing regimen, not the slogan. That article underwent full weld, paint, window and hatch integration, then shipped to Mojave for testing. The docking adapter fit check completed in October 2025. The MMOD shield covers the entire station. The oxygen tube valve system replenishes atmosphere every breath cycle. Eight specialized trash tanks each hold five days of wet waste for a crew of four. These are not marketing bullets; they are requirements the hardware must satisfy before the first private astronaut, defined by leadership as "any individual who has decided they have enough discretionary income… but also to do meaningful work", boards.

Action and Curiosity show up in the human-centric design choices that separate Haven-1 from the "utilitarian… nothing but cables and wires and computers" aesthetic of ISS. The 1.1-meter domed window provides a 180-degree Earth view. Interior tones are warm, wood-grained, smooth. An adjustable air bladder in the sleep station simulates gravity's pressure on the body so limbs can relax. Six CMGs with fast-spinning flywheels on gimbals handle attitude control without thrusters. Deployable solar panels from DHV Technology deliver 13.2 kW peak. Every one of these decisions started as a difficult question, how to make a crew of four effective for 30-day missions, and ended as engineered hardware.

Excellence — "superior quality does not happen by accident… clear intention, informed direction, skillful execution", is visible in the progression from pathfinder to qualification article to flight unit. The Haven-1 primary structure is the first of its class built in the U.S. since the Shuttle era. That record is not a press release; it is a weld inspection report and a shipping manifest.

Respect, "celebrate our differences… welcome dialogue, show respect, and have empathy", extends beyond the team to the customer base. France, the Czech Republic via ESA, and the UK Space Agency have signed agreements for private astronaut missions to ISS and Haven-1. Sovereign nations outside the original ISS consortium now have a path to low-Earth orbit. The commercial platform model preserves IP ownership for experiments and manufactured goods, a freedom government stations do not offer. Jed McCaleb's long-term vision, stated on the careers page, frames the whole effort: "create artificial gravity stations, allowing humanity to live and work in space without long-term harm to the body." The principles are the operating system; the hardware is the output.

What the interview actually tests

Vast does not publish a step‑by‑step interview playbook. What the record shows — repeatedly, is a culture that prizes extreme ownership, first‑principles engineering, and the ability to deliver flight hardware on an aggressive timeline. Those priorities shape what any candidate should expect, even if the exact stage count isn't public.

The careers page lists seven operating principles plus "Our shared mission." Each reads like an evaluation rubric. "All in" and "Making it happen" signal that interviewers will probe for evidence you have owned outcomes end‑to‑end, not just contributed to a subsystem but driven a hardware project from concept through test. "Committed to safety and reliability" means you will be asked how you verify designs when lives depend on them. "Action" and "Curiosity" suggest a bias toward practical problem‑solving over theoretical elegance.

Board data shows Vast hiring for director‑level roles across the same functions, all with salary bands ranging from roughly $188k to $289k. At that level, the interview is less about technical syntax and more about whether you can run a team that ships flight articles. The company has built three major structures in two years, including that milestone. That pace implies a hiring bar that filters for people who have operated in hardware‑rich, schedule‑driven environments and who can adapt when requirements shift weekly.

First‑party board postings also list a Mission Assurance Engineer role at $160k–$268k, a reminder that safety culture permeates every discipline. Candidates should be ready to discuss how they have balanced schedule pressure against risk acceptance, and to cite specific instances where they stopped a flow to fix a root cause.

The partnership with SpaceX for launch and the incremental, low‑cost approach to station development matter: interviewers will test whether you understand the difference between a one‑off prototype and a system that must operate reliably for months on orbit. They will also assess cultural alignment with a founder‑funded company that moves faster than traditional aerospace but cannot tolerate a "move fast and break things" ethos when the thing breaking is a pressure vessel.

In the absence of a published process, the safest preparation is to treat every conversation as a mutual assessment of ownership. Bring concrete hardware stories, what you built, how you tested it, what went wrong, and what you changed. Demonstrate fluency in the language of margins, interfaces, and verification closure. And be ready to explain why you want to build a commercial space station now, not in a decade. The company's public milestones, Haven‑1 welded, pressure‑tested, entering integration, targeting a 2026 launch, make clear the window for contribution is narrow. The interview is your proof you can step into that window and deliver.

Pay, equity, and the asymmetric bet

Vast's compensation structure reflects a company that pays for ownership in a hardware-rich, schedule-driven environment. The clearest window comes from Zero G Talent's first-party board data, 145 salaried roles tracked with a company-wide band of $78k–$265k (median $195k) (Zero G Talent's figures put). At the director level, where Vast concentrates hiring for Haven-1's 2027 launch, the numbers cluster tightly:

The spread tells a story. Fluid Systems Test tops the range, $288k ceiling, because propulsion and fluid systems are on the critical path for a station that must pressurize, maintain atmosphere, and dock with Crew Dragon. Sub Assemblies Manufacturing sits at the same floor ($188k) but with a lower ceiling, reflecting Vast's vertical integration push: the company machines Haven-1's flight panels and assembles battery packs in-house, so manufacturing directors own delivery schedules, not vendor management. Mission Assurance spans the widest band ($160k–$268k), covering both early-career engineers building flight-hardware discipline and senior leads who sign off on qualification articles.

Below director level, the $78k floor aligns with early-career mechanical, electrical, and software engineers who join Vast for the hardware cadence: three major structures completed in two years, Haven Demo flown and deorbited, Haven-1 primary structure in final assembly. The median at $195k sits above many legacy aerospace primes for equivalent tenure, but below SpaceX's top quartile, consistent with a venture-backed company funded by Jed McCaleb (Ripple cofounder) that has not yet reached orbit.

Equity details are not public. Vast has not disclosed option pool size, strike-price methodology, or refresh cadence in any filing or leadership interview. With 145 salaried roles and that target, the cap table is likely concentrated around McCaleb and early institutional investors. Candidates should assume a standard private-company structure, four-year vest, one-year cliff, no liquidity until a tender offer or exit, and ask directly about refresh grants at promotion milestones. The company's "progressive complexity" strategy (Haven-1 → Haven-2 → NASA CLD Phase 2) means equity value hinges on technical milestones, not revenue traction.

Benefits follow a similar pattern: no public benefits guide, no Glassdoor aggregate with statistical weight. The research shows Vast operates from a new Long Beach headquarters with integrated manufacturing, machining Haven-1's flight panels in-house and assembling battery packs from cell screening through pack assembly and testing. That physical footprint suggests on-site expectations. The careers page lists long-term equity incentive program, 401(k) retirement plan, generous PTO programs with annual cash-out option, paid parental leave, comprehensive medical, dental, and vision insurance, and subsidized meals, fitness memberships, and additional health and wellness benefits.

The philosophy, inferred from pay bands and hiring tempo, is cash-competitive for hardware engineers who want flight heritage on a commercial station, with equity as the asymmetric upside if Haven-1 reaches orbit and wins CLD Phase 2. The $188k director floor signals that Vast expects leads to operate with minimal oversight, owning a subsystem from design review through on-orbit commissioning. The $265k company-wide ceiling (excluding the Fluid Systems Test outlier) suggests a flat hierarchy: you don't get VP titles to unlock higher cash; you get flight hardware that survives qualification.

For candidates, the negotiation lever is scope. A Director, Loads & Dynamics who can demonstrate they've flown structures on Falcon 9, or better, Crew Dragon, can anchor at the top of the band. A Mission Assurance Engineer with NASA human-rating experience owns the upper quartile. The band rewards proven flight hardware judgment, not years of service. That aligns with the culture described in other sections: rapid iteration, clear accountability, and a launch date that does not slip for process.

Who stays, who leaves

Vast's culture filters for a specific profile: engineers and operators who treat ambiguity as a design variable, not a blocker. The company's incremental, hardware-rich approach, building flight hardware fast, testing it, breaking it, and iterating, demands people who can move from CAD to cut metal without a requirements document landing in their inbox first. That tempo shows up in employee accounts. BuiltIn's 2026 culture review highlights empowerment and collaboration as strengths, but explicitly flags pace, uneven team experiences, and scaling processes as friction points. The message is consistent: you get autonomy, but you pay for it in velocity.

People who thrive here share three traits. First, they have a hardware-first mindset. Vast's roadmap, Haven modules, artificial-gravity stations, persistent LEO presence, means mechanical, thermal, fluids, and structures engineers aren't supporting a software product; they are the product. Second, they operate with owner-level accountability. The compensation structure detailed in the previous section reflects a structure where individual contribution scales directly with scope. Director-level postings all sit in the $188k–$289k range, signaling that leadership expects technical depth and delivery ownership at every level. Third, they align with the mission viscerally. LinkedIn's company description frames the work as "pioneering the next giant leap toward long-term living and thriving in space while ensuring America's continuous human presence in low-Earth orbit." That language isn't marketing fluff — it's the filter.

The mismatch profile is equally clear. If you require mature processes, defined handoffs, or a predictable 40-hour rhythm, Vast will frustrate you. The BuiltIn review's "uneven team experiences" note maps directly to a scaling organization where some groups have tooling and leads while others are still building both. Engineers who thrive on architectural purity, clean interfaces, frozen requirements, waterfall-adjacent discipline, will clash with the "test early, test often" reality. So will specialists who want to go deep on one subsystem without touching integration. The hardware-rich method forces cross-disciplinary exposure: a fluids test director coordinates with structures, avionics, and manufacturing daily. That's the job.

Motivation matters more than pedigree. The interview process probes for past instances where the candidate owned an outcome end-to-end, made a call with incomplete data, and recovered from a hardware failure. The compensation philosophy reinforces it, equity is meaningful because the company's valuation trajectory ties directly to flight milestones, not funding rounds.

In short: Vast rewards builders who treat schedule pressure as a forcing function, not a complaint. It penalizes anyone waiting for permission, process, or perfection. The mission — continuous human presence in LEO, is the only north star. If that doesn't pull you forward when the test article fails, the culture will feel like a grind. If it does, the grind is the point.
