About the role

Experienced process engineer to develop and own manufacturing processes for optical transceivers, focusing on 800G and 1.6T programs, from process definition to high-volume production, collaborating with contract manufacturers and internal teams.

Responsibilities

  • Define, develop, prove out, and deploy manufacturing processes for new products across the transceiver assembly flow (e.g., die attach, wire bond, active alignment, and general assembly), implementing continuous improvement projects to achieve yield, throughput, efficiency, scrap, and quality targets.
  • Own manufacturing process documentation (process specs, work instructions, control plans, FMEA) and review/approve process changes implemented on the production line.
  • Maintain end-to-end manufacturing ownership: ensure all changes to product, process, materials, and equipment are managed under change control per established QMS requirements.
  • Lead or support equipment selection and new equipment introduction: define statement of purpose/requirements, work with suppliers and stakeholders to develop process algorithms, machine hardware, and software from buy-off through release to manufacturing.
  • Collaborate with design engineering and contract manufacturing teams to execute, improve, and sustain manufacturing processes; ensure design for manufacturing (DFM) guidelines are met.
  • Collaborate with the quality team for planning and execution of qualification, reliability, and burn-in testing in support of new product introduction and process changes.
  • Analyze process and yield data to identify root cause of excursions and drive corrective/preventive actions across relevant assembly processes.
  • Prepare process reports by collecting, analyzing, and summarizing information and trends.
  • Automate manufacturing processes where possible to support scale-up and high-volume production.

Qualifications

  • Bachelor's degree in Electrical Engineering, Industrial Engineering, Mechanical Engineering, Physics, or related field, plus 7+ years of experience in high-volume optical transceiver and/or laser manufacturing.
  • Excellent problem-solving and analytical skills.
  • In-depth technical knowledge and hands-on experience in the design, development, selection, and implementation of manufacturing processes, equipment, materials, and methodologies for optical assemblies.
  • Expert in one or more optical transceiver assembly processes, such as die attach, wire bond, active optical alignment, general assembly, product testing, or burn-in.
  • Expertise in data analysis, statistical process control (SPC), and report generation.
  • In-depth understanding of quality management systems and applicable quality standard requirements.
  • Data query and data analysis skills using statistical tools and techniques.
  • Expertise in optics failure analysis (FA) processes and tools.
  • Ability to work well in a geographically diverse cross-functional team.
  • Good command of English communication, both verbal and written, including in-person and virtual presentation skills.
  • International travel required.
