Senior Propulsion Engineer Verified today

About the role

You will be a critical contributor in the Mojave, CA office advancing propulsion systems for Voyager's sub-orbital VTVL vehicles. You will work directly on all aspects of propulsion systems, from initial component and system sizing through design, analysis, fabrication, and test. You will report to the Propulsion Lead as part of a joint propulsion team collaborating with the Pittsburgh, PA office.

Responsibilities

• Support the engineering team in the design and test of rocket propulsion systems using cryogenic propellants
• Size components of propulsion systems including combustion devices, valves, propellant feed lines, turbomachinery, tanks, and pressurization systems
• Design and analyze combustion device elements including injectors, combustion chambers, nozzles, gas generators, cooling channels, and related technology
• Build and run propulsion system fluid-thermal models to predict component and system behavior
• Perform trade studies to guide design and operational decisions
• Lead the creation of hardware drawings to support manufacturing
• Create component specifications to guide vendor interactions and support procurement
• Develop test plans, execute tests, and post-process results for component and system testing
• Contribute to and participate in technical readiness and safety reviews for testing activities
• Perform risk assessment and mitigation planning
• Write and present technical reports

Required qualifications

• B.S. in Mechanical or Aerospace Engineering
