Senior Mechanical Engineer
On-siteAlameda, California, United States
Job Summary
Design, analyze, and deliver mechanical and fluid systems for launch operations, ranging from cryogenic propellant loading to structural components. Own end-to-end design of valves, actuators, plumbing, mechanisms, and structures, creating 3D CAD models, detailed drawings, and GD&T while managing P&IDs and flow diagrams. Perform structural, thermal, and fluid analyses to validate performance and ensure safety margins, then drive prototyping, build support, and integration with hands-on troubleshooting on the floor. Plan system-level test campaigns for qualification and acceptance, define operating procedures for startup and emergency conditions, and partner cross-functionally with propulsion, avionics, and manufacturing teams. Produce clear documentation including requirements, design reviews, test plans, and compliance packages.
Required Qualifications
- 3–6+ 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)
- Employment is contingent upon the candidates status as a U.S. Person or ability to obtain an appropriate export license
- Required background checks
- Eligibility for government contracts or a security clearance (where applicable)
Desired 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
