• Collaborate with Engineering, Physics, and Program Management teams to refine system architecture and requirements
• Drive rapid prototyping and proof‑of‑concept development in a fast‑paced R&D environment
• Own mechanical design deliverables including Bills of Materials (BOMs), drawings, tolerance analyses, and test fixtures
• Support New Product Introduction (NPI) activities, including early production builds and training manufacturing teams
• Perform and guide sustaining engineering, incorporating production, quality, and field feedback into design improvements
• Apply engineering judgment to designs involving plastics, structural metals, rotating mechanisms, and electromechanical assemblies
• Provide technical mentorship and design guidance to junior mechanical engineers

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering
• 7+ years of progressive mechanical engineering experience in product development environments
• Proven experience designing one or more of the following:
  • Handheld or portable devices
  • Electromechanical or robotic systems
  • Large‑scale industrial or scanning equipment
• Solid understanding of manufacturing processes including:
  • Molded plastics
  • Structural components
  • Mechanical mechanisms
• Experience with SolidWorks or Onshape (preferred)
• Working knowledge of finite element analysis (FEA) strongly preferred
• Strong interpersonal and communication skills, with the ability to collaborate cross‑functionally
• Demonstrated ability to take ownership of designs from concept through production
