Propulsion 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 looking for a<strong> Propulsion Engineer</strong>, reporting to the<strong> Senior Manager, Haven-1 propulsion</strong>, to support the development of the systems that will be required for the design and build of artificial-gravity human-rated space stations.</p> <p>This will be a <strong>full-time</strong>,&nbsp;<strong>exempt </strong>position located in our <strong>Long Beach</strong>&nbsp;location.&nbsp;</p> <p><strong>Responsibilities:&nbsp;</strong></p> <ul> <li>Collaborate closely with propulsion and systems design teams to provide manufacturing and assembly input for component hardware such as valves, regulators, tubing, ducting, manifolds, COPVs, fittings, and instrumentation used in propulsion and pressurization systems.</li> <li>Develop, qualify, and optimize manufacturing processes and production equipment for propulsion components, with a focus on repeatability, quality, cost, and flight reliability.</li> <li>Create and maintain detailed manufacturing plans, assembly procedures, travelers, and work instructions to support production of propulsion hardware across development, qualification, and flight builds.</li> <li>Support propulsion systems including propellant feed, pressurization, venting, purge, and safety-critical fluid systems.</li> <li>Identify and resolve manufacturing challenges through hands-on troubleshooting, root cause analysis, and implementation of corrective and preventive actions.</li> <li>Work directly with suppliers to ensure timely delivery of high-quality propulsion components, including review and approval of supplier manufacturing processes and documentation.</li> <li>Perform hands-on assembly, integration, and testing of propulsion components and
