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 transformative technologies. Our goal is to develop high‑speed photonics products purpose‑built to power AI infrastructure and high‑performance computing. This is a ground‑floor opportunity to rethink the optical layer from silicon up, working with world‑class engineers to solve the hardest challenges in scaling optical systems.
About The Role – Optical Product Test Engineer As an Optical Product Test Engineer, you will play a critical role in validating and ensuring the quality of Lumilens’ photonic components, modules, and systems. The role includes hands‑on production testing, test development, and reporting, supporting new product introduction (NPI) and volume manufacturing. You’ll collaborate with optical design, hardware, and manufacturing teams to calibrate, characterize, and troubleshoot next‑generation photonics technologies that will power tomorrow’s AI and HPC infrastructure.
Primary Duties & Responsibilities
Perform characterization and testing of fiber optic components and modules
Analyze test results to ensure compliance with performance specifications and quality standards
Maintain accurate, detailed records of test procedures and outcomes
Generate comprehensive test reports for internal and external stakeholders
Support troubleshooting and root‑cause analysis to resolve product issues
Design, plan, and conduct optical and fiber testing on components, devices, and systems
Collaborate with cross‑functional engineering teams to support NPI and manufacturing ramp
Education & Experience
BS or MS in Engineering, Physics, Optics, or a related technical field
8+ years of industry experience in optical or fiber component testing (preferred)
Prior exposure to photonics, telecom, or high‑speed networking systems is a plus
Skills
Hands‑on experience with optical test instruments (e.g., optical spectrum analyzers, power meters, polarization controllers, bit‑error‑rate testers)
Familiarity with communication interfaces and test automation tools
Ability to write or adapt scripts for automation (Python, LabVIEW, Visual Basic; shell scripting a plus)
Strong analytical skills to interpret complex test data and identify patterns or anomalies
Resourceful problem‑solver with ability to apply knowledge creatively to test challenges
Capable of managing multiple test projects and priorities in a fast‑paced environment
Strong communication and documentation skills; able to train and mentor peers when needed
What we offer
Competitive salary commensurate with experience
Comprehensive benefits package, including health insurance
Professional development and certification opportunities
Access to cutting‑edge optical/photonics test environments and tools
A collaborative, cross‑functional team dedicated to solving some of the hardest challenges in photonics
Equal‑opportunity employer: All qualified applicants will receive consideration without regard to race, color, religion, gender, identity, orientation, veteran status, disability, or any other legally protected status
Seniority level Mid‑Senior level
Employment type Full‑time
Job function Quality Assurance
