Motive Workforce
Overview
We are seeking a
Senior Mechanical Engineer
to join the
Valves & Fluid Systems team
of a next-generation
space launch provider . In this high-impact role, you’ll
own the design, development, and qualification
of flight-critical fluid system components—including
high-pressure valves, actuators, cryogenic plumbing, and quick-disconnects —from concept through flight. This is a
hands-on, high-accountability engineering position
where you’ll collaborate with technicians, test engineers, and manufacturing teams to deliver hardware that meets mission-critical deadlines. You’ll also shape best practices, mentor junior engineers, and drive continuous improvement in a fast-paced aerospace environment. What You’ll Do
Own mechanical design for valves, actuators, and fluid system hardware Perform structural, thermal, and tolerance analyses to validate designs Lead hardware development from prototype to hot-fire and environmental testing Drive root-cause investigations and corrective actions for test/production issues Collaborate with propulsion, test, and structures teams for seamless integration Deliver complete engineering documentation to support build & test operations Mentor and guide junior engineers, shaping design standards and team practices What You Bring
Bachelor’s degree in Mechanical, Aerospace, or related engineering discipline 4+ years’ experience in
aerospace, defense, or high-reliability industries Proven track record of taking hardware from
concept through flight/production Proficiency in
CAD
(NX, SolidWorks, etc.) and strong
GD&T fundamentals Solid background in
FEA, structural, and thermal simulations Deep understanding of
manufacturing processes
(machining, welding, brazing, heat treating) Hands-on mindset—comfortable assembling, debugging, and collaborating with technicians Strong communication skills and a
team-first mindset Preferred Skills
Experience with
high-pressure systems (6000+ psi)
or
cryogenics (LOX, RP-1) Background in complex mechanisms (actuators, safe & arm devices, etc.) Familiarity with
NASA, ASME, or MIL standards Startup/early-stage aerospace experience in fast-paced environments Leadership in failure investigations and corrective action plans Track record of mentoring engineers and leading cross-functional efforts Why Join Us?
Be part of a team pushing the boundaries of
space exploration
and
launch technology Work on
flight-proven hardware
critical to next-gen launch vehicles Collaborate with some of the
brightest engineers in aerospace Competitive pay, comprehensive benefits, and career growth opportunities Location:
Bay Area, CA Compensation:
$130,000 – $160,000 base salary (plus bonus & benefits) Employment Type:
Full-time Ready to launch your career?
