Senior Electronics & Avionics Engineer

<div class="content-intro"><p>At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. Vast is developing next-generation space stations to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Using an incremental, hardware-rich and low-cost approach, Vast is rapidly developing its multi-module Haven Station. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches, followed by additional Haven modules to enable permanent human presence by 2030. Our team is all-in, committed to executing our mission safely and on time. If you want to work with the most talented people on Earth furthering space exploration for humanity, come join us.</p></div><p>Vast is seeking a <strong>Senior Electronics &amp; Avionics Engineer</strong> to own avionics development for a new constellation-ready spacecraft bus — a product line designed to scale to hundreds of spacecraft per year.</p> <p>This is a&nbsp;<strong>full-time, exempt</strong> position located in our <strong>Long Beach </strong>location.</p> <p><strong>About this role:</strong></p> <p>We're building a new satellite bus launching in Q4 2027. The avionics suite spans actuator controllers, power management electronics, high-speed payload interfaces, and sensor front-ends — a mix of in-house development, heritage reuse from other Vast programs, and COTS. You'll own every in-house development end-to-end: from make/buy/reuse decision through flight hardware delivery.</p> <p>This is the most schedule-critical individual contributor role on the program. Multiple box developments run in parallel on tight timelines, and you're on the critical path for the entire satellite. As the product line scales from our first 10-satellite build to hundreds of spacecraft per year, you'll drive the transition from prototype to production — designing boards that can be built at rate, not just once.</p> <p><strong>Responsibilities:&nbsp;</strong></p> <ul> <li>Drive make, buy, or reuse decisions for all avionics boxes</li> <li>Own all in-house box developments end-to-end: kickoff, Rev 1 schematic/layout, component procurement, PCBA fab, board bring-up, radiation test, environmental test, CDR, Rev A delta design, flight build, ATP/QTP</li> <li>Manage PCBA critical path — schematic capture, layout, design reviews, component procurement, board fabrication, assembly, staking, conformal coating</li> <li>Own board bring-up an
