We are seeking a Senior Mechanical Engineer to join the Valves & Fluid Systems team of a next-generation space launch provider. In this role, you'll lead the design, development, and qualification of fluid system components that are critical to launch success. This includes high-pressure valves, actuators, cryogenic plumbing, and quick-disconnects-owning designs from concept through flight.

This is a high-accountability, hands-on engineering position where you'll collaborate with technicians, test engineers, and manufacturing teams to ensure hardware is designed, tested, and delivered on time. You'll also play a key role in mentoring junior engineers, shaping team standards, and driving continuous improvement.
Key Responsibilities
  • Own the mechanical design for valves, actuators, and other fluid system hardware
  • Perform structural, thermal, and tolerance analyses to validate designs
  • Lead hardware development from prototyping to environmental and hot-fire testing
  • Drive root cause investigations and corrective actions for test or production issues
  • Collaborate cross-functionally with propulsion, test, and structures teams for seamless integration
  • Deliver complete engineering documentation to support manufacturing and test operations
  • Provide mentorship and guidance to junior engineers while contributing to design best practices
Compensation
  • Base salary range: $130,000 - $160,000 per year (Bay Area market range; excludes bonus and benefits)


Minimum Qualifications
  • Bachelor's degree in Mechanical, Aerospace, or related engineering field
  • 4+ years of experience in mechanical engineering across aerospace, defense, or other high-reliability industries
  • Proven track record owning hardware from concept through testing and production
  • Proficiency in CAD (NX, SolidWorks, etc.) with strong GD&T fundamentals
  • Strong background in FEA, structural, and thermal simulations
  • Deep understanding of manufacturing processes (machining, welding, brazing, heat treating)
  • Hands-on builder comfortable with assembly, debugging, and technician collaboration
  • Team-first mindset with the ability to self-direct, take feedback, and adapt as needed
Preferred Skills / Multipliers
  • Experience designing and qualifying high-pressure (6000+ psi) or cryogenic systems (LOX, RP-1, etc.)
  • Background in complex mechanical mechanisms (actuators, safe & arm devices, arm/fire devices)
  • Experience managing Tech Data Packages, compliance plans, and program reviews (PDR/CDR/TRR)
  • Familiarity with ASME, NASA, or MIL standards
  • Startup/early-stage company experience in fast-paced environments
  • Track record of leading failure investigations and implementing corrective actions
  • Demonstrated mentorship of engineers and leadership of cross-disciplinary efforts
Other Requirements
  • Must be a U.S. Person under ITAR/EAR (citizen, permanent resident, refugee, or asylee) or eligible for licensing
