From chip to chip optical interconnects to scalable photonic engines, Lumilens is unlocking a new era of computing, faster, cooler, and massively more efficient.\nWe’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. \nIf you're looking for mission, momentum, and the chance to make an outsized impact, jump on the rocket ship. We’re just getting started.\nPOSITION OVERVIEW\nWe are seeking an experienced Optical Transceiver Product Engineer to play a critical role in bringing our next generation optical transceiver products from development into high volume manufacturing. In this role, you will own manufacturing readiness and product execution across the product lifecycle, working closely with contract manufacturers, suppliers, and cross functional teams in design, process engineering, quality, and operations. You will help drive the successful launch and scale up of advanced transceiver platforms, with a strong focus on product quality, yield, reliability, and cost. This is a high impact opportunity for someone with deep expertise in the optical transceiver industry, particularly with 800G and 1.6T products, who thrives in a fast moving environment and wants to help shape the future of optical connectivity.\nDUTIES/RESPONSIBILITIES\nEnd-to-end manufacturing ownership: Ensure all the changes to product, processes, materials, etc. are under change control and follow established QMS requirements.\n\nResponsible for product yield, quality and reliability, as the lead contact for delivering products to customers\n\nResponsible for the accuracy of manufacturing BOM and driving product quality, operational productivity, and total cost of manufacturing\n\nResponsible for analyzing, defining, developing, and executing continuous improvement plans to achieve yield, cycle time, throughput, and scrap reduction.\n\nTrack manufacturing test results and ensure compliance with specification\n\nResponsible for product documentation and specifications\n\nCollaborate with quality team for planning and execution of qualification testing\n\nCollaborate with design team and process engineering to ensure design for manufacturing (DFM) guidelines are met\n\nPrepare product and process reports by collecting, analyzing, and summarising information and trends\n\nSKILLS/EXPERIENCE\nBachelor’s degree in Electrical Engineering, Industrial Engineering, or a related field, with 7+ years of experience in high-volume optical transceiver manufacturing.\n\nExcellent problem-solving and analytical skills.\n\nDirect experience with optical transceiver manufacturing and engineering, including 800G and 1.6T products.\n\nStrong technical depth in manufacturing BOMs, yield analysis, root cause problem solving, and process implementation for optical products.\n\nExperience with transceiver products and optical assembly processes such as wire bond, die bond, active optical alignment, product test, and burn-in is strongly preferred.\n\nExperience in ongoing reliability testing and quality control best practices.\n\nExpertise in data analysis, statistical process control (SPC), and report generation.\n\nIn depth understanding of the quality management system and quality standard requirements.\n\nExpertise in optics FA processes and tools.\n\nAbility to work well in a geographically diverse cross-functional team.\n\nGood command in English communication both verbal and written, including in-person and virtual presentation skills.\n\nInternational travel required.","description_format":"text","description_chars":4016,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate
