About the role
- Mesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh.
- Our hardware platform demands mechanical systems engineered for micron-scale precision and high-volume automated manufacturing from the start. We are seeking a Lead Mechanical Engineer to own mechanical development across our hardware platform—personally designing and analyzing critical assemblies while building and leading the team that delivers them. You
Responsibilities
- Lead mechanical execution from concept through production ramp, personally designing and analyzing high-impact components and assemblies
- Architect electro-mechanical assemblies for highly automated, scalable manufacturing-ensuring designs enable autonomous assembly, precision placement, micron-scale metallurgical processes, and robust DFM execution
- Lead structural, thermal, and reliability analysis and decision-making
- Drive design-for-manufacturability, design-for-assembly, and design-for-test across the mechanical subsystem
- own supplier readiness from prototyping through production ramp
- Interface with optical, electrical, firmware, and process engineering teams to define system-level interfaces, integration constraints, and co-design trade-offs
- Provide day-to-day technical leadership to a small and growing team of mechanical engineers who own scoped subsystems
- Lead design reviews and ensure subsystem designs align with system-level requirements, schedule, and quality targets
- Establish mechanical design standards, documentation discipline, and review rigor across the team
- Lead structural, thermal, and reliability analysis and decision-making; identify mechanical risks early and define validation strategies to retire them
Requirements
- Bachelor's or Master's degree in mechanical engineering or a related discipline
- 4+ years of experience designing complex hardware systems, with demonstrated ownership of major subsystems or full products through production ramp
- Experience designing tight-tolerance precision assemblies with multi-domain interfaces (optical, electrical, thermal, or mechanical)
- Proficiency in professional 3D CAD tools (NX, SolidWorks, Creo, or equivalent)
- Proficiency in structural analysis tools (e.g., ANSYS Mechanical or equivalent FEA)
- Experience leading technical efforts across cross-functional hardware teams
- Experience mentoring engineers or leading small technical teams
- Strong first-principles foundation in mechanics of materials, heat transfer, and tolerance analysis
- Experience working directly with suppliers and contract manufacturers to drive production readiness and component qualification
- Willingness to work extended hours and weekends as needed.
Nice to have
- Experience in optical, photonic, semiconductor, or high-performance computing hardware development
- Experience with high-density packaging, advanced thermal management, or chip-on-carrier/module-level mechanical integration
- Thermal simulation experience (e.g., ANSYS Mechanical, Icepak, Fluent, or equivalent CFD tools)
- Experience designing for highly automated assembly environments, including familiarity with robotic pick-and-place, precision alignment, and in-line inspection constraints
- Experience with optomechanical design, including kinematic mounting, athermalization, or fiber-to-chip alignment fixturing
- Familiarity with materials selection for photonic or semiconductor-adjacent applications, including CTE matching, outgassing, and cleanliness requirements
- Experience with reliability qualification methodologies (e.g., HALT, HASS, or Telcordia-style environmental testing)
- Familiarity with configuration management, engineering change processes, and PLM tools
Compensation
- Lead Mechanical Engineer: $160,000.00 - $190,000.00/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.
