Join our team of problem solvers as we add new chapters to the history of spaceflight!

As part of a small group of engineers you will serve as the technical integrator for a LOX/LNG booster engine. You will sit at the intersection of every technical discipline on the program owning the systems architecture driving requirements from top-level customer needs down through subsystems and ensuring that every design decision rolls up into a system that meets its performance reliability and operability goals. This is a role with real ownership and real influence on a team that moves fast dives deep and does not settle for good enough.

Responsibilities include but are not limited to:

• Own the engine-level systems architecture ensuring design decisions made at the subsystem level are coherent traceable and optimized for the system as a whole

• Sufficient propulsion fundamentals to engage credibly with subsystem engineers across combustion devices turbomachinery and feed systems
• Experience with requirements management tools such as DOORS DNG Jama or equivalent and Atlassian tools including Jira and Confluence

Preferred Qualifications:

• Prior experience as a lead or sole systems engineer on a liquid rocket engine program with direct accountability for technical integrity
• Experience with high-performance engine cycles
• System Safety analysis experience including FMECA FTA and FHA in a flight-critical environment
• Experience with reliability maintainability and supportability (RMS) analysis and execution
• Prior experience at a fast-moving launch vehicle or propulsion developer where hardware has flown
