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. 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 optics, systems, and scale. 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 We are seeking an Active Alignment Equipment Engineer to serve as the primary equipment engineering interface between Lumilens’ optical design team, package design team, manufacturing team and worldwide equipment suppliers. This role focuses on the active alignment machine for optics such as FAU, lens, isolator, PIC chip, etc. from new machine technology development, process development to qualification of the machines. The candidate must have solid hands-on experience in FAU-PIC alignment machine, very familiar with the key technologies such as stages, controllers, power meters, MPO connectors, laser sources, algorithms, as well as mechanical parts. Key Responsibilities · Identify, develop and qualify FAU-PIC equipment suppliers worldwide, for Pluggable/NPO/CPO packages. · Lead co-design and qualification of the machine, risk analysis and mitigation plan with suppliers for on-time delivery and installation. · Support active alignment process in mass production line, NPI line and R&D lab. · Engage with package production teams during the process development and qualification. Required qualifications · B.S. or M.S. in Mechanical, Electrical or Optical Engineering. · 5+ years of working experience in active alignment machine design, assembly or testing, with solid knowledge in coupling efficiency, FAU, PIC, UV epoxy, UPH, and equipment qualification procedures. · Must be very familiar with the whole active alignment machine industry. Can select and identify different equipment suppliers for different products’ production and R&D. · Familiar with Solidworks, understand circuit schematics and optical simulations. • Fluency in English to communicate with English speaking stakeholders • 30~50% travel in Asian countries.
