Senior Mechanical Engineer

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
• Identify mechanical risks early and define validation strategies to retire them, including test fixture specification and prototype validation planning
• Contribute meaningfully to system-level architecture discussions, influencing packaging strategy, interface definitions, and cross-domain trade-offs with optical, electrical, and thermal stakeholders
• 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

Qualifications

• 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
• Strong first-principles foundation in mechanics of materials, heat transfer, and tolerance analysis
• 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
• Willingness to work extended hours and weekends as needed

Preferred Experience

• 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
