<candidate>Xona Put a Satellite in Orbit in June. It's Now Hiring FPGA Engineers Who Can Shape Navigation Signals That GPS Can't Match.</candidate>

GPS Was Never Built for This

GPS signals arrive at Earth's surface at roughly one-billionth of a watt, weak enough that buildings, terrain, and inexpensive radio modules can spoof or block them. The system also offers no cryptographic authentication, meaning a receiver can't verify that a navigation fix is real. For a military drone or an autonomous vehicle making split-second decisions, those aren't edge cases. They're daily operational risks.

The LEO satellite market is projected to grow from $16.1 billion in 2025 to $55.5 billion by 2035, according to Future Market Insights. Within that, the dedicated LEO position, navigation, and timing segment is tracking its own steep curve, driven by sectors that can't tolerate GPS's known weaknesses: urban air mobility, autonomous vehicles, defense platforms, and critical infrastructure timing.

Xona Space Systems is building Pulsar, a low-Earth orbit constellation designed to address both problems at once. The planned constellation of roughly 260 satellites will broadcast dual L-band navigation signals near the GPS L1 and L5 frequencies, but from orbits roughly 1,200 kilometers above Earth, far closer than GPS satellites at roughly 20,200 kilometers. That proximity translates to signal strength Xona says is up to 100 times greater than legacy GPS, enough to penetrate urban canyons and dense foliage where current signals fail. The system also layers in signal authentication, letting receivers confirm each fix's legitimacy.

Pulsar is designed for interoperability with existing GNSS receivers rather than requiring entirely new hardware, a choice detailed in a technical paper on arXiv examining LEO navigation compatibility with current L-band standards. Xona has said the constellation will augment GPS initially and eventually function as a standalone PNT source.

A technology demonstration satellite, Huginn, launched in May 2022. The first operational satellite, Pulsar-0, followed in June 2025, putting hardware in orbit and shifting the company from paper architecture to flight-proven system. That transition, from demonstration to operational constellation, is what's now driving Xona's workforce expansion, and why Montreal has become a focal point for the hiring ahead.

Pulsar-0 Is in Orbit — and the Hiring Has Already Started

Xona put its first production-class satellite into orbit on June 23, 2025, and the company's hiring engine kicked in almost immediately.

Pulsar-0 launched aboard SpaceX's Transporter-14 rideshare mission from Vandenberg Space Force Base, reaching a sun-synchronous orbit where it began testing the signals that will underpin the planned LEO PNT constellation. The satellite, designated Xona IOV and cataloged as NORAD ID 64541, was developed in partnership with Aerospacelab. Xona made a deliberate tradeoff to get there fast: the company launched Pulsar-0 without a propulsion system, accepting a shorter mission lifetime in exchange for on-orbit validation data sooner rather than later.

That speed-first logic now extends to staffing. Zero G Talent's board shows two Xona roles added in the past seven days alone, and the open positions tell a clear story about where the company is heading. In Montreal, Xona is hiring a Senior Product Developer (Fullstack) and an Embedded Software Developer focused on security and platform integration. In Burlingame, California, the company has listed a GNSS Engineer, an Enterprise Applications Manager, and a Finance Systems Manager, with salaries ranging from $130,000 to $180,000 per year.

The roles map directly to what Pulsar-0 is supposed to prove. Embedded software and GNSS engineering positions signal that Xona is moving from demonstration to production, refining the signal processing, security hardening, and platform integration needed to scale from one satellite to a full constellation. The Montreal-heavy split also confirms the Canadian hub as a significant engineering center for the company.

Indeed's listings, which show roughly 33 to 35 open positions at Xona depending on the snapshot, suggest the hiring wave extends well beyond what any single job board captures. The company's own careers page frames it plainly: Xona is building the next era of global PNT, and it needs people to do it. With Pulsar-0 now transmitting from orbit, the timeline for that buildout has stopped being theoretical.

Why Montreal Has Become a PNT Engineering Hub

Xona is headquartered in Burlingame, but its hiring footprint extends into Montreal. Two of the five roles the company added to Zero G Talent's board in the past week are based in Montreal: a finance and accounting manager and an embedded software developer focused on security and platform integration. The choice isn't accidental. It's a bet on one of North America's deepest aerospace engineering pools, a cluster that's simultaneously expanding and straining under a generational talent shift.

Montreal's aerospace sector entered 2026 adding thousands of jobs while losing experienced engineers to retirement, according to a Kitalent analysis of the region's labor market. The pipeline is full at the junior end but thinning at the mid-career level, precisely the gap a company like Xona needs to fill with targeted recruitment. LinkedIn lists 124 aerospace engineer positions open in the city right now. ZipRecruiter shows 388 aerospace engineer job postings in the broader Montreal, QC market, with hourly rates hitting $50. A Talenbrium report projects Canada's aerospace and defense engineering talent pool will grow 15% by 2025, driven by demand for autonomous systems and advanced navigation technology, the exact domains Xona operates in.

The city's draw goes beyond raw headcount. Montreal hosts a concentration of RF and satellite communications expertise built over decades around the Canadian Space Agency, MDA, and a network of suppliers that grew up around them. For a company building a LEO navigation constellation, that matters more than a generic tech hub's app-developer supply.

Xona's satellite manufacturing path runs through another channel. The company contracted Belgian manufacturer Aerospacelab to build eight Pulsar satellites, with launches set to begin later this year. Aerospacelab previously built Pulsar-0. Xona has said it's building out its own manufacturing capabilities in California, but the Aerospacelab deal serves as a "transition manufacturing partner," buying Xona time to stand up its own lines while getting hardware in orbit. That arrangement keeps the company's near-term production footprint in Europe, but its engineering hiring is pulling from Montreal's RF and embedded-systems talent base to develop the payloads and ground systems those satellites will depend on.

The two Montreal-based roles currently on Zero G Talent's board don't look like satellite manufacturing jobs on paper. They point to something else: Xona is building a functional operational hub in the city, not just posting individual engineering contracts. An embedded software developer working on security and platform integration is the kind of hire that supports payload development, ground segment software, and the hardened PNT signal architecture that differentiates Xona's constellation from GPS. A finance and accounting manager in Montreal, paired with senior finance roles in Burlingame, suggests the Canadian office is scaling into a semi-autonomous unit.

For engineers weighing the move, Montreal offers a lower cost of living than the San Francisco Bay Area, with aerospace salaries that remain competitive by Canadian standards. The retirement wave draining mid-career talent means openings exist. The question is whether Xona can move fast enough to capture them before competitors with deeper pockets do.

What the $92M Series B Actually Buys

Xona announced $92 million in new capital on June 26, 2025, a figure that pushes its total funding to $150 million. The round was led by Craft Ventures, with participation from Stellar Ventures, Seraphim Ventures, Toyota Ventures, First Spark, Industrious Ventures, Future Ventures, and NGP Capital. On top of the equity raise, Xona secured a $20 million non-dilutive award from SpaceWERX, the US Space Force's innovation arm, money that doesn't dilute ownership and signals direct defense-sector confidence in the Pulsar constellation.

CEO Brian Manning framed the raise as a shift in phase: "With this funding, we're accelerating from R&D to delivery at scale." The company's own breakdown of where the money goes is specific: continued Pulsar constellation development and deployment, expanded manufacturing capacity, and team growth across four categories: engineering, operations, customer success, and go-to-market.

That last category is what makes this round different from a typical satellite startup fundraise. Xona isn't just building satellites; it's building the ground systems, signal-processing infrastructure, and commercial wrapper around a navigation service. Manning's own language, "an entirely new layer of infrastructure that requires world-class talent across mission operations, ground systems, signal processing, customer success, go-to-market, and more," makes clear the hiring is meant to cover the full stack, not just the spacecraft.

The defense angle matters for the hiring timeline. The SpaceWERX STRATFI award is non-dilutive, meaning it comes with milestones and deliverables tied to national-security requirements. That kind of contract forces a company to staff up on a schedule, not just when the product roadmap allows. Xona's job board reflects this: roles like GNSS Engineer in Burlingame and Embedded Software Developer for Security & Platform Integration in Montreal point directly to the kind of signal-processing and hardened-navigation work the SpaceWERX award would fund.

The manufacturing expansion is the other hiring driver. Xona plans to move from a single satellite (Pulsar-0, already in orbit) to hundreds in the coming years. Scaling from one production-class satellite to a full constellation requires not just more RF and FPGA engineers but the operations and finance staff to run a production line. The Montreal-based Finance and Accounting Manager and Enterprise Applications Manager roles on Zero G Talent's board suggest Xona is already building out the operational backbone at its Canadian hub, not just the engineering team.

At $150 million total raised, Xona is now one of the better-funded private PNT companies in the LEO space. The question the next round of hires will answer is whether it can convert that capital into a working constellation before competitors, or before GPS modernization closes the gap Pulsar is designed to fill.

What the Job Postings Reveal About Xona's Technical Bets

The job postings tell the story the press releases only hint at. Xona isn't just launching satellites — it's building an entire signal chain from orbit to receiver, and the roles it's hiring for map directly onto the technical risks that will make or break the Pulsar constellation.

Start with the FPGA Engineer listings, which appear across multiple boards in both Burlingame and Montreal. The role is specific: translate DSP algorithms into RTL for Xilinx RFSoC chips, implement correlation and tracking modules for GNSS waveforms, and verify timing closure on hardware that will fly on every Pulsar satellite. The Montreal posting on Simplify calls out "real-time signal processing of GNSS signals" and requires experience with fixed-point arithmetic and AXI high-speed interfaces. The Burlingame version on Toyota Ventures adds ARM-based MPSoC systems and Embedded Linux on Zynq UltraScale+. Together, these aren't generic FPGA slots — they describe the signal-processing core of Xona's navigation payload, the piece that generates and shapes the Pulsar waveform before it ever leaves the satellite.

Then there's the Orbits and Operations Engineer, listed on Toyota Ventures and SimplyHired for the Burlingame office. The posting spans orbit determination, maneuver planning, real-time payload operations, and health monitoring. That's a hybrid role covering both the spacecraft bus and the navigation payload, which signals that Xona is still close enough to its early constellation phase that orbital mechanics and payload performance aren't separate workstreams. As the constellation scales, those functions typically split into dedicated teams. Right now, one engineer owns both.

The Embedded Software Developer role on Zero G Talent's own board, listed under its Montreal operations, focuses on security and platform integration, a pairing that maps onto Xona's stated emphasis on military-grade encryption and anti-jamming protection. The GNSS Engineer posting in Burlingame rounds out the navigation-specific hiring.

What's missing is just as telling. There are no listings for propulsion engineers, thermal analysts, or structural designers, the roles you'd expect if Xona were developing satellite buses in-house. That gap, combined with the concentration of RF, FPGA, and embedded roles, points to a company that outsources or partners on the spacecraft platform and keeps the navigation payload and signal architecture as its proprietary core.

Zero G Talent's board currently shows two recently added roles in Montreal, a Senior Fullstack Product Developer and an Embedded Software Developer for security and platform integration, plus the GNSS Engineer and finance systems roles in Burlingame. The mix confirms the dual-track buildout: Montreal handling software and payload integration, Burlingame running manufacturing and navigation engineering.

The hiring profile matches the technical roadmap Manning described when the Series B closed: move from proof-of-concept to active global infrastructure. Pulsar-0 proved the signal works. These roles are about proving it can be manufactured, encrypted, and delivered at scale, week after satellite week, from a factory that doesn't exist yet at full capacity.

Two Sectors Pulling Xona Toward Production Contracts

The demand signals behind Xona's hiring surge aren't theoretical. Defense and autonomous systems are actively pulling the company's PNT technology toward production contracts, and both have urgent reasons to want an alternative to GPS.

The military case is the most immediate. When Russia invaded Ukraine in 2022, GPS jamming became a frontline problem almost overnight. Two years later, jamming technology has only grown more sophisticated, and the defense industry is scrambling for navigation systems that don't depend on traditional GNSS signals. The US Army is funding magnetic navigation (MagNav) through the Defense Innovation Unit, a passive system that reads Earth's magnetic field rather than satellite signals. Advanced Navigation has delivered a hybrid inertial-and-laser-aided solution for GNSS-denied environments. The common thread: militaries no longer trust GPS alone. A LEO constellation like Xona's Pulsar, operating at lower altitudes with stronger signal power and a different orbital geometry than GPS, is inherently harder to jam. That's the value proposition defense buyers are evaluating right now.

The autonomous-vehicle and UAV market is the other pull. MarketsandMarkets projects the LEO PNT market growing from $0.07 billion in 2025 to $0.57 billion by 2030, a 53.9% compound annual growth rate. GM Insights points to autonomous vehicles, UAVs, and connected IoT devices as primary drivers, all of which need low-latency, high-accuracy positioning that GPS struggles to deliver in tunnels, dense urban canyons, and remote areas. Navistrat Analytics notes that LEO PNT is already being integrated into autonomous vehicles, maritime platforms, and military systems for exactly these edge cases.

Xona's hiring reflects both pipelines. The open GNSS Engineer role in Burlingame and the embedded software developer position in Montreal, focused on security and platform integration, map directly to the kind of hardened, low-latency signal processing that defense and autonomy customers require. These aren't generalist satellite roles. They're the specific engineering positions you fill when you're building toward production contracts with customers who can't afford to lose a signal.

Who Else Is Racing to Build LEO PNT?

The LEO PNT market is projected to grow from $70 million in 2025 to $570 million by 2030, according to MarketsandMarkets. That growth has drawn at least ten organizations into the race, representing more than 2,500 planned satellites if every announced constellation reaches full deployment. But the field breaks down into three distinct tiers, and only a handful of players have the funding, hardware, and government backing to matter in the near term.

The well-funded startups sit at the top. Xona has raised over $320 million in total funding across its Series B and subsequent rounds, the most of any commercial entrant, and already has a production satellite, Pulsar-0, in orbit transmitting encrypted PNT signals. TrustPoint, based in Herndon, Virginia, is pursuing a defense-first strategy with encrypted C-band signals and announced its first successful LEO PNT demonstration in January 2026. Both companies are hiring: Xona lists open roles on Zero G Talent's board spanning embedded software, GNSS engineering, and finance positions across its Burlingame and Montreal offices.

The defense primes and incumbents form the second tier. L3Harris is developing military PNT under DARPA's Blackjack and CASTLE programs, with a contract from the US Space Force's Space Systems Command to explore a Resilient-GPS LEO SmallSat constellation. Thales Alenia Space was selected by ESA in March 2024 to deliver one of two European LEO-PNT orbit demonstrators, including a five-satellite constellation. Safran, through its Syrlinks subsidiary, received a contract in June 2025 to provide payload equipment for Airbus-built Eutelsat LEO satellites with enhanced PNT capabilities. These are established contractors with existing government relationships and decades of satellite manufacturing experience.

The operational outlier is Satelles, which has taken a fundamentally different approach by hosting PNT signals on the existing Iridium constellation rather than building from scratch. That piggyback strategy means Satelles has been commercially operational since 2016, years ahead of any competitor. The trade-off is accuracy: Satelles cannot match the signal strength or precision of a purpose-built constellation, but it offers a functional GPS backup today, not in 2028.

The signal-band split between Xona and TrustPoint is the most consequential technical divide in the market. Xona broadcasts L-band, the same frequency GPS uses, meaning existing GPS receivers can be adapted to pick up Pulsar signals without new hardware. That is a significant adoption advantage. TrustPoint's C-band approach requires new receiver hardware entirely, but operates on frequencies that GPS jammers do not currently target. The market may ultimately need both: L-band for commercial scale, C-band for high-security defense applications.

Capital requirements are the other filter. Building, launching, and operating a 200-plus-satellite constellation runs into the hundreds of millions of dollars. That barrier limits the competitive field to companies with deep pockets or government sponsors. Xona's $320 million in private funding and TrustPoint's DoD backing have effectively established them as the two leading commercial contenders, with L3Harris and Thales Alenia Space as the government-program heavyweights.

For engineers evaluating where to apply, the signal is clear: Xona is the only commercial player with a production satellite already in orbit and a hiring pipeline that spans RF, embedded software, and GNSS engineering across two countries. The others are either earlier in development, locked into government timelines, or offering a narrower technical scope. The window to get in at a company that is both funded and flying is shorter than most candidates realize.
