Principal Propulsion Engineer - Engines

Application close date:

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. 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
• Develop, decompose, and allocate requirements across subsystems, maintaining clear traceability and a credible path to verification for every requirement
• Define and control all key interfaces between engine subsystems and between the engine and vehicle, resolving conflicts before they become integration problems
• Lead engine-level trade studies with analytical rigor, driving clear recommendations that advance the program rather than cataloguing options
• Actively engage with test data, anomaly investigations, and design iterations to identify optimization opportunities and push system performance
• Identify technical risks early, develop mitigation strategies, and communicate program status with clarity and honesty to leadership and stakeholders
• Serve as the technical hub across a wide range of stakeholders - subsystem engineers, vehicle teams, test operations, and program leadership
• Coordinate System Safety analysis across the engine, ensuring complete hazard coverage and no gaps across subsystems
• Lead and prepare for major program reviews, setting a high bar for technical readiness and ensuring the team is prepared to defend their designs
• Maintain configuration discipline across drawings, interface control documents, and design documentation so the team always has an accurate picture of the current system

Minimum Qualifications:

• B.S. or higher in Aerospace Engineering, Mechanical Engineering, Systems Engineering, or a related technical field
• 10+ years of experience in propulsion or aerospace system development, with meaningful time spent on liquid rocket engine programs
• Hands-on experience with requirements development, interface definition, and system-level verification on flight or flight-like hardware
• 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
