The company combines custom silicon, integrated sensors, and software into a unified platform for robotics, mobility, and next-generation automation. Lyte is headquartered in Sunnyvale, California, with a global presence. For more information, visit www.lyte.ai\nIf you’re excited about building impactful technology in a dynamic, hands-on environment, we’d love to hear from you!\n About the role\nWe are seeking a highly motivated Photonics Validation Engineer to join our team. In this role, you will be responsible for validating photonics sub-systems and packaged opto-electronic modules - building test infrastructure from the ground up and driving failure analysis from component level through module level. This position requires hands-on expertise in optical and electro-optic testing, strong troubleshooting instincts, and the ability to work closely with a multidisciplinary engineering team. Experience with EIC control, firmware/FPGA/ASIC-based test environments, coherent communications, and data analysis is essential. Background in free space optics, micro-optics, packaging, and III-V semiconductor physics is a plus. You will work alongside a world-class, cross-functional team in a fast-paced and rapidly growing environment.\nWhat you'll do\nBuild test benches and automated test setups from scratch for photonics systems, components, and packaged opto-electronic devices\nDesign, execute, and refine test plans and validation methodologies across wafer, chip, eval board, and sub-module levels\nPerform spectrum analysis, noise analysis and FFT-based signal analysis\nValidate coherent communication systems and modules (e.g., coherent receivers, DSP-linked subsystems)\nPerform failure analysis efforts - root-causing device and system failures across optical, electrical, and firmware layers, and driving corrective actions\nPerform passive optical testing (insertion loss, return loss, wavelength response, etc.)\nTroubleshoot and debug test setups and design issues, identifying and resolving challenges\nAnalyze and visualize test data to characterize device performance and identify trends or deviations\nInterface with EIC controls, firmware, and embedded software during test bring-up\nCollaborate with FPGA/ASIC teams to support test automation, debug, and validation workflows\nWork closely with cross-functional teams (design, packaging, manufacturing, product) to drive issues from detection to resolution\nDocument test procedures, results, and failure analyses; communicate findings clearly to internal stakeholders\nSupport the transition of test methodologies from R&D into high-volume manufacturing\nRequired Qualifications\nBachelor's degree in Electrical Engineering, Photonics, Applied Physics, or a related field; a Master's or Ph.D. is welcome but not required\n3-7 years of relevant industry or applied research experience in photonics validation, optical testing, or opto-electronic systems\nHands-on experience testing photonic or opto-electronic components, subsystems, or packaged modules\nExperience building test benches, fixtures, or automated test setups from the ground up\nStrong failure-analysis and troubleshooting skills, with the ability to isolate root causes across optical, electrical, and firmware domains\nHands-on experience with optical and electrical lab equipment, including spectrum analyzers, oscilloscopes, network analyzers, and optical power meters\nProficiency in data analysis, automation, and visualization using Python, MATLAB, or similar tools\nWorking knowledge of coherent optical communication principles\nStrong written and verbal communication skills, with the ability to work effectively across engineering disciplines\nPreferred Qualifications\nExperience interfacing with EIC controls, firmware, or embedded software during test bring-up\nExperience with FPGA- or ASIC-based test environments and validation workflows\nExperience with spectrum, noise, or FFT-based signal analysis\nBackground in free-space optics, micro-optics, photonics packaging, or III-V semiconductor physics\nExperience transitioning test methodologies from R&D into manufacturing or high-volume production\nBenefits (subject to location and local regulations)\nCompetitive salary and equity \nComprehensive medical, dental, and vision coverage \n401(k) retirement plan \nFlexible vacation and time-off policy \nCollaborative, fast-paced, and inclusive work environment \nOpportunity to work on cutting-edge technologies with a highly cross-functional
