Job Description

Job Title: Senior Optical Process Engineer. Location: Milpitas, California, United States

You will work across packaging, processing, and qualification in a fast-paced environment, collaborating with internal teams and external suppliers to deliver high-quality quantum subsystems that operate at room temperature and cryogenic conditions.

Duties:

• Develop assembly process flows and build sub-assemblies for quantum computer subsystems using electronics and photonics chips on PCBAs.
• Support opto-mechanical packaging for both vacuum and cryogenic environments;
• Finalize designs and assembly processes using DFM, DFQ, and FMEA methods.
• Deliver and qualify tooling, equipment, and fixtures from suppliers with process capability analysis and reporting.
• Release process documentation, work instructions, and control plans with change control management.
• Train, audit, and transition processes to operations teams for volume manufacturing;
