Senior Mechanical Engineer

Alameda CA Full-Time On-Site

Build the systems that make spaceflight possible.

Our client is seeking a Senior Mechanical Engineer to design analyze and deliver the mechanical and fluid systems behind launch operationseverything from cryogenic propellant loading and high-pressure plumbing to structural components and ground/test infrastructure. Youll own hardware from clean-sheet design through prototyping test and integration working side-by-side with propulsion avionics test and manufacturing team.

If you thrive on complex engineering problems fast iteration and hands-on hardware work this role is for you.

What Youll Do

• Own end-to-end design of mechanical and fluid systems including valves actuators plumbing mechanisms and structures
• Create and maintain 3D CAD models detailed drawings and GD&T; manage P&IDs and flow diagrams as needed
• Perform and interpret structural thermal and fluid analyses to validate performance and ensure safety margins
• Drive prototyping build support and integration including hands-on troubleshooting on the floor and during testing
• Plan and support system-level test campaigns (qualification acceptance and troubleshooting); provide field/launch support when required
• Define operating procedures including startup/shutdown and off-nominal or emergency conditions
• Partner cross-functionally with propulsion test avionics and manufacturing to enable buildable testable designs
• Produce clear documentation: requirements design reviews test plans nonconformances/corrective actions and compliance packages

What Were Looking For (Required)

• 36 years of mechanical design experience in aerospace robotics automotive energy or similarly rigorous hardware environments
• Demonstrated ability to take designs from concept prototype test production
• Proficiency with CAD tools such as NX SolidWorks or Creo and comfort with drawing release workflows
• Working knowledge of FEA and/or thermal analysis (commercial or internal tools)
• Experience with high-pressure and/or cryogenic fluid systems
• B.S. in Mechanical Engineering Aerospace Engineering or related discipline
• Comfortable working hands-on (prototyping assembly support test setup troubleshooting)

Nice to Have (Preferred Qualifications)

• Familiarity with relevant standards such as ASME B31.3 welding standards (e.g. AWS) or aerospace safety practices
• Experience with 6000 psi systems and/or propellants like LOX RP-1 or comparable cryogenic/hazardous fluids
• Background in startup / rapid prototyping environments with high ownership and fast iteration cycles
• Strong root cause analysis and corrective action leadership (failure investigations containment long-term fixes)
• Experience mentoring junior engineers or leading cross-functional technical efforts

Why This Role

Youll be trusted to make design decisions that directly affect safety reliability and mission successwhile building real hardware at speed.
