About the role
- This is a senior individual contributor role reserved for engineers who demonstrate exceptional technical depth, ownership, and execution capability.
Responsibilities
- Independently own mechanical development of major subsystems from concept through production, including requirements definition, design, analysis, prototyping, and ramp support
- Design precision electro-mechanical assemblies with rigorous tolerance control across optical, electrical, and mechanical interfaces
- Perform and defend structural, thermal, and tolerance analysis to drive design decisions, validate performance margins, and support design reviews
- Drive design-for-manufacturability and design-for-automation decisions with minimal oversight, ensuring mechanical designs support automated assembly, precision placement, and high-yield production
- Lead supplier technical discussions, component qualification, and production ramp execution, including resolution of supplier-side manufacturing issues
- Establish and maintain mechanical design documentation, including detailed drawings with GD&T, specifications, and engineering change records
- Support root-cause investigation of mechanical failures across prototype, validation, and production stages, driving corrective action back into design guidelines
Requirements
- Bachelor's or Master's degree in mechanical engineering or a related discipline
- 5+ years of experience designing complex hardware systems, with demonstrated exceptional individual contributor capability in production hardware environments
- Proven ownership of major subsystems through production ramp, including direct accountability for performance, schedule, and manufacturability outcomes
- Experience designing tight-tolerance precision assemblies with multi-domain interfaces
- Proficiency in professional 3D CAD tools (NX, SolidWorks, Creo, or equivalent)
- Proficiency in structural or thermal analysis tools (e.g., ANSYS Mechanical or equivalent FEA)
- Experience working directly with suppliers and driving technical decisions through component qualification and production readiness
- Strong first-principles foundation in mechanics of materials, heat transfer, and tolerance analysis
- Willingness to work extended hours and weekends as needed
Nice to have
- Experience in optical, photonic, semiconductor, or high-performance computing hardware development
- Advanced simulation experience, including thermal analysis (e.g., ANSYS Icepak, Fluent, or equivalent CFD tools)
- Experience designing hardware for highly automated manufacturing environments, including familiarity with robotic assembly, precision fixturing, and in-line metrology constraints
- Experience with optomechanical design, including kinematic mounting, athermalization, or fiber-to-chip alignment
- Experience with materials selection for photonic or semiconductor-adjacent applications, including CTE matching, outgassing, and cleanliness considerations
- Familiarity with reliability qualification methodologies (e.g., HALT, HASS, or Telcordia-style environmental testing)
- Experience with configuration management, revision control, and PLM tools
Compensation
- Senior Mechanical Engineer: $140,000.00 - $180,000.00/per year
- Title and base salary are determined on a case by case basis commensurate with experience and merit.
- In addition to base salary, compensation for this role includes:
- Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
- Relocation assistance to sunny Los Angeles.
Benefits
- Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.
- Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.
- Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).
- 401(k) retirement plan access.
