Senior Propulsion Engineer

The role

You will advance the development of propulsion systems for sub-orbital VTVL vehicles. You will work on all aspects of propulsion systems including sizing, design, analysis, fabrication, and test.

What you will do

• 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

Required qualifications

• B.S. in Mechanical or Aerospace Engineering
• 6+ years of relevant experience in rocket propulsion system development
• Experience with cryogenic propellants
• Experience in designing and analyzing high-pressure fluid and/or pneumatic systems
• Proven capability to develop conceptual designs, perform trade studies, and down select to a design baseline

Nice to have

• M.S. in Mechanical or Aerospace Engineering
• Experience with a variety of cryogenic propulsion systems and various engine cycles
• Experience with Computational Fluid Dynamics (ANSYS Fluent or CFX preferred)
• Experience leveraging additive manufacturing in engine design
• Proficient in fluid/thermal software for rocket engine development (GFSSP, RTE, RPA) and for system level modeling (Amesim or Thermal Desktop)
• Familiar with CAD (SolidWorks preferred) and lifecycle management tools
• Ability to take ownership of and prioritize tasks in a fast-paced environment with changing needs and requirements
• Experience with advanced rocket engine designs and concepts, especially RDRE’s
• Analytical/scientific programming (Python, C/C++, MATLAB, Fortran)
• Hands-on fabrication skills and a willingness to be hands-on with pathfinder hardware

Benefits

• Flexible Time Off (FTO)
• Comprehensive medical, dental, and vision coverage
• Flexible, affordable gym memberships
• 401(k) retirement plan with a 50% company match on contributions up to 8%
• Company wellness programs
• Additional voluntary benefits and employee support resources
