Senior Mechanical Engineer, Long Range
$145,000–$220,000 year
On-siteSouth San Francisco, California, United States
Job Summary
Own specific Long Range mechanical subsystems from concept through sustained production, translating operational requirements into quantitative performance targets and design architectures. Produce detailed CAD models, tolerance stacks, and manufacturing drawings to enable supplier quotes and inspection plans, while running first-principles analysis and FEA simulations to validate structural reliability. Lead hands-on build-test-iterate campaigns, define verification matrices, and drive root-cause investigations to implement design fixes with clear acceptance criteria. Partner daily with cross-functional teams to resolve tradeoffs and act as escalation owner for mechanical issues impacting fleet availability, supporting field deployments and production startups as required.
Required Qualifications
- 4+ years industry experience designing electromechanical and structural assemblies
- demonstrable ownership of complex subassemblies through full product cycles (design → qualification → production ramp)
- Deep CAD fluency (managing 20–30 part subassemblies and top-level integration)
- rigorous GD&T skills
- experience producing manufacturing-ready drawings and inspection criteria
- Proven track record applying FEA, hand calculations (beam, buckling, bolted joints), tolerance analysis, and test correlation to establish safety and reliability margins for flight or field-critical hardware
- Hands-on prototyping and test experience: you build fixtures, run validation campaigns, and close design loops from test data to production intent
- Direct supplier engagement experience: negotiating DFM changes, resolving quality issues, and translating supplier capabilities into producible designs
- Experience with structural components, mechanisms, fastener systems, composites or metallic airframe-scale assemblies, and designing for serviceability in field conditions
- Willingness and ability to travel to suppliers, production sites, and field depots on an as-needed basis (periodic domestic and occasional international travel)
- Strong bias for taking end-to-end ownership: you will stay with issues until verified fixes are in production and fielded
Desired Qualifications
- Aerospace or automotive validation experience
- composites design
- high-efficiency electric powertrain exposure
- NX proficiency
- prior experience scaling prototypes to injection molding, stamping, or extrusion processes
