What you will do

• Develop automated routines to execute and analyze silicon photonics, III-V, laser, and optoelectronic measurements, including optical power, insertion loss, LIV sweeps, extinction ratio, modulation bandwidth, and coupling efficiency.
• Design and validate optomechanical fixtures, probe cards, and custom PCBs for R&D and high-volume manufacturing.
• Build software control systems, search algorithms, and machine vision tools for multi-axis optical alignment and chip-to-chip or FAU-to-chip coupling optimization.
• Correlate measurement data with physical device behavior, monitor process variations, and drive hardware yield improvements.
• Establish test specifications, Gauge R&R studies, calibration procedures, qualification procedures, measurement best practices, data quality checks, and documentation standards.
• Translate characterization results into recommendations for laser design, photonics integration, packaging, system architecture, and reliability teams.

Requirements

• BS, MS, or PhD in Electrical Engineering, Physics, Photonics, Optical Engineering, or a related field.
• 6+ years of hands-on experience in photonics, laser, semiconductor, or optoelectronic testing.
• Fundamental understanding of optical, electrical, and optoelectrical measurement techniques and instrumentation.
• Proficiency in Python or similar object-oriented programming languages.

Nice to have

• Experience with advanced optical sensing technologies, including lidar, silicon photonics, or related fields.
• Experience designing automated optical alignment systems with multi-axis motion control, alignment search algorithms, and real-time feedback optimization.
• Experience in experimental design and statistical analysis of large characterization datasets, including drawing conclusions and providing actionable feedback to design teams.
• Experience architecting automated test systems from concept through production deployment in semiconductor, photonics, or advanced hardware environments.
• Experience with complex high-speed optical and electrical measurements using photodetectors, RF spectrum analyzers, VNAs, and high-speed oscilloscopes, including hardware calibration and de-embedding.

Culture & Benefits

• Work alongside experienced engineers on complex self-driving and transportation problems.
• In-person collaboration is expected, with at least 3 office days per week and potentially more based on operational needs.
• Annual bonus, equity compensation, and employee benefits are provided.
• Work is guided by safety, integrity, ambitious goals, collaboration, inclusion, and reasonable accommodation commitments.
