Senior Mechanical Product Design Engineer – Photonics Platform (Shanghai)

About the role

We are seeking a highly skilled Senior Photonics Platform Hardware Qualification & System Product Design Engineer to support the development, qualification, and productization of a next‑generation Photonics Platform. This role combines hands‑on photonics module/system qualification with mechanical and opto‑mechanical product design ownership, spanning the full lifecycle from early prototyping through engineering validation and mass production.

Key responsibilities

• Act as a technical expert in at least two R&D domains (Optics, Electronics, Motion, or System Engineering) supporting module integration, calibration, and qualification.
• Define and execute module qualification and calibration plans, verifying performance against specifications.
• Lead qualification of complex components and subsystems, performing risk assessment and mitigation.
• Own mechanical and opto‑mechanical design of photonics platform modules, creating 3D CAD models, 2D drawings, BOMs, and GD&T.
• Perform engineering analyses such as hand calculations, FEA, thermal analysis, and tolerance stack‑up.
• Develop and qualify production documentation, including build books, assembly procedures, and test flows.
• Support NPI, prototype builds, and ramp to mass production, collaborating with manufacturing partners worldwide.
• Mentor junior engineers and present technical concepts, design trade‑offs, and risk assessments to stakeholders.

Required profile

• Bachelor's degree or higher in Mechanical Engineering, Optical Engineering, Electrical Engineering, Physics, Materials Science, or a related field.
• 6–10+ years of experience in hardware development, photonics systems, opto‑mechanical design, or platform engineering.
• Proven experience in module/system qualification, calibration, and performance validation.
• Strong proficiency with 3D CAD and 2D drafting tools (NX, Creo, SolidWorks or equivalent).
• Solid understanding of mechanical engineering fundamentals (statics, dynamics, heat transfer, materials).
• Hands‑on experience working with manufacturing partners in high‑volume or advanced engineering environments.
• Excellent communication skills to convey complex technical topics across disciplines.
• Ability to work independently, manage ambiguity, and solve complex system‑level problems.
