About the role

  • As a Mechanical Engineer at Lightmatter, you will sit at the critical intersection of silicon photonics, advanced 3D packaging, and extreme-density thermal management.
  • you will be the practical execution engine transforming complex electro-optical concepts into scalable, manufacturable hardware.
  • While this role focuses on flawless technical execution rather than top-level project architecture, your hands-on impact will be immense.

Responsibilities

  • Design, test, analyze, integrate, qualify and document hardware of moderate to high complexity, in a dynamic startup environment.
  • Responsible for mechanical design from generating CAD and drawings, to BOM generation and crafting work instructions.
  • Fully understand project requirements and timelines while identifying gaps and drive to closure with the stakeholders
  • Initiate and drive design reviews while managing the resulting feedback and change requests.
  • Collaborate in root-cause-analysis and technical investigations with cross-functional teams.
  • Drive hands-on in-house build and integration activities, scaling from initial prototype fabrication to leading external CMs for high-volume production.
  • Manage outside fabricators to ensure correct build-to-print and quality workmanship.
  • Actively mitigate and manage lead-time issues with the supply chain team.
  • Collaborate with relevant cross-functional engineering teams to understand dependencies.

Requirements

  • Bachelor's degree in Mechanical Engineering or related fields
  • 5+ years of experience in system mechanical design with multiple successful product releases
  • Industry experience in electronics packaging
  • Proficient in a 3D CAD solid modeling software package such as SolidWorks
  • Familiar with both thermal and structural testing and analysis
  • Possess a strong understanding in the application of heat transfer principles, strength of materials, materials selection, design for vibration environments and the ability to apply those principles to unique mechanical design challenges.
  • Strong communication and adaptive in execution
  • Preferred Qualifications
  • This role is open to two different roles. Level and salary range is dependent on education, years of industry experience, and interview performance.
