Job summary

Mesh Optical Technologies is seeking a Lead Mechanical Engineer to own mechanical development across our hardware platform, designing critical assemblies and leading a growing team for scalable, autonomous manufacturing with minimal manual intervention.

You will translate product architecture into system strategy, define packaging and tolerance architecture, and drive DFM/ DFA across interfaces to ensure manufacturability and reliability.

Qualifications

• Bachelor's or Master's degree in mechanical engineering or a related discipline.
• 4+ years of experience designing complex hardware systems, with ownership of major subsystems or full products through production ramp
• Strong first-principles foundation in mechanics of materials, heat transfer, and tolerance analysis
• 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 working directly with suppliers and contract manufacturers to drive production readiness and component qualification
• Experience leading technical efforts across cross-functional hardware teams
• Experience mentoring engineers or leading small technical teams
• Willingness to work extended hours and weekends as needed.

Responsibilities

• Lead mechanical execution from concept through production ramp, personally designing and analyzing high-impact components and assemblies
• Translate product architecture into mechanical system strategy, defining the packaging approach and tolerance architecture across optical, electrical, and mechanical interfaces
• 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; identify mechanical risks early and define validation strategies to retire them
• 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
• Mentor engineers, raise the technical bar, and contribute to hiring and growth of the mechanical function
