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 team of world-class engineers solving some of the hardest challenges in scaling optical systems. Every line of code, every design decision, every 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
As an Optical Manufacturing Test Engineer, you will play a critical role in validating and ensuring the quality of Lumilens’ photonic components, modules, and systems. This role blends hands-on production testing with hardware test development and reporting, supporting both new product introduction (NPI) and volume manufacturing. You’ll work closely with optical design, hardware, and manufacturing teams to perform design for manufacturing, calibration, characterization, and troubleshooting duties for next-generation photonics technologies.
DUTIES/RESPONSIBILITIES
- End-to-end manufacturing test ownership: Ensure all the changes to test hardware, processes, etc. are under change control and follow established QMS requirements. This includes equipment selection and specification, tester BOM and estimated cost, test schematic diagram, test flows, work instructions, etc.
- Responsible for tester documentation and specifications. Analyze test results to ensure compliance with performance specifications and quality standards.
- Develop, assemble, validate, buy off and release the testers for production.
- Responsible for product test yield, with quality and reliability.
- Responsible for analyzing, defining, developing, and executing continuous improvement plans to achieve test yield, cycle time, throughput, and scrap reduction.
- Collaborate with quality teams for the planning and execution of qualification tests.
- Collaborate with design teams and process engineering to ensure design for manufacturing (DFM) and design for test (DFT) guidelines are met.
