Job description

About Lumilens

At Lumilens we are building the critical photonics infrastructure that powers tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing faster, cooler, and massively more efficient.

We’re a well‑funded startup backed by Mayfield and led by veterans who’ve built and scaled some of the most transformative technologies in the industry. At Lumilens, we’re developing high‑speed photonics products purpose‑built to power the future of AI infrastructure and high performance computing. This isn’t incremental innovation; it’s a ground‑floor opportunity to rethink the optical layer from the silicon up.

You’ll work alongside a world‑class engineering team solving some of the hardest challenges in scaling optical systems. Every line of code, design decision, and breakthrough you help deliver will shape the infrastructure of tomorrow. If you’re looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We’re just getting started.

Position Overview

We are seeking an experienced Process Engineer who will be responsible for the development and oversight of manufacturing processes supporting our optical transceiver roadmap. The successful candidate will work closely with contract manufacturers, suppliers, and internal cross‑functional development teams to meet product objectives and instill a culture of quality and continuous improvement. The engineer must be eager to learn and explore new processes and solutions for high‑volume manufacturing of optical transceivers used in AI data centers.

Duties/Responsibilities

• Define, develop, prove and deploy the manufacturing process for new products and implement continuous improvement projects to achieve product yield, throughput, efficiency, scrap and quality targets.
• Responsible for manufacturing process documentation and for reviewing and approving the processes implemented on the production line.
• End‑to‑end manufacturing ownership: ensure all changes to product, processes, materials, etc. are under change control and follow established QMS requirements.
• Collaborate with design engineering and contract manufacturing teams to execute, improve and sustain the manufacturing processes and to meet design for manufacturing (DFM) guidelines.
• Collaborate with the quality team for planning and execution of qualification testing.
• Prepare process reports by collecting, analyzing, and summarizing information and trends.
• Automate all manufacturing processes, where possible.
• Engage with equipment selection, create the statement of purpose, and work with suppliers and stakeholders in developing the algorithm, machine hardware and software from buy‑off to release in manufacturing.

Skills/Experience

• Bachelor’s degree in Electrical Engineering, Industrial Engineering, Mechanical Engineering, Physics, or related field, plus 7 years 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 design, development, selection, implementation of manufacturing processes, equipment, materials and methodologies for the optical assemblies.
• Expertise in one or more of the optical transceiver assembly processes, such as wire bond, die bond, active optical alignment, product testing, burn‑in, etc.
• Expertise in data analysis, statistical process control (SPC) and report generation.
• In‑depth understanding of the quality management system and quality standard requirements.
• Data query and data analysis skills with use of statistical tools and techniques.
• Expertise in optics 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.
