Lumilens is building photonics infrastructure for AI supercomputing, including chip-to-chip optical interconnects and scalable photonic engines. The company is Series B-funded and led by industry veterans.
This Senior Process Engineer role owns manufacturing process development and deployment for optical transceiver products across the assembly flow, including die attach, wire bond, active alignment, and general assembly. You will drive processes from initial definition through high-volume production for current and next-generation 800G and 1.6T module programs.
Key responsibilities include:
- Define, develop, and deploy manufacturing processes for transceiver assembly, implementing continuous improvement to achieve yield, throughput, efficiency, and quality targets
- Own manufacturing documentation (process specs, work instructions, control plans, FMEA) and approve production line changes
- Manage end-to-end manufacturing ownership with change control per QMS requirements
- Lead equipment selection and new equipment introduction, defining requirements and working with suppliers on process algorithms and software
- Collaborate with design engineering and contract manufacturers on DFM guidelines and process execution
- Partner with quality teams on qualification, reliability, and burn-in testing for new products
- Analyze process and yield data to identify root causes and drive corrective/preventive actions
- Prepare process reports and automate manufacturing processes to support scale-up
Required qualifications: Bachelor's degree in Electrical, Industrial, or Mechanical Engineering, Physics, or related field, plus 7+ years in high-volume optical transceiver and/or laser manufacturing. Expert-level knowledge of optical assembly processes (die attach, wire bond, active alignment), statistical process control, quality management systems, and optics failure analysis. Strong data analysis skills, cross-functional collaboration ability, and excellent English communication. International travel required.
