Laser Test Engineer

Location: Hybrid - SF Employment: Full-time Develop and qualify Volantis’s testing procedures for custom lasers and scale for mass production. You will own development and implementation of testing and reliability procedures for our first- and second-generation custom laser designs, and their integration with the wafer-scale interposer. Responsibilities • Partnering with the laser design team to define test plans, specifications and pass/fail criteria for new individually addressable VCSEL array designs. • Characterizing prototype devices (LIV, spectral, far-field/beam profile, polarization, thermal and high-speed modulation) and delivering timely analysis that feeds back into design iterations. • Managing test data, including databases, wafer maps, yield analysis and SPC, to track device performance and process variation in conjunction with the designers. • Designing, building and maintaining wafer- and die-level prober systems, test fixtures and automated test software. • Owning qualification and ramp-up of VCSEL array product testing systems, scaling from R&D characterization to high-volume production test. • Working with the laser design, packaging and wafer-scale interposer teams to prove out reliability of the VCSEL itself and the overall system. Requirements • Deep hands-on experience with semiconductor laser (preferably VCSEL) testing, characterization, validation, reliability and qualification. • Experience designing prober systems, test fixtures and related software automation • Proficiency with optical and electrical test equipment such as SMUs, optical spectrum analyzers, power meters, VNAs, and beam profilers • Ability to work independently as well as in cross-functional teams including quality and packaging Nice to have • Experience qualifying and using contract manufacturers for large volume production test of VCSELs • Experience testing high-density VCSEL arrays, both top and bottom side emitting. • High speed direct modulation laser diode test experience • Understanding of sources of process variation and statistical process control for yield improvement • Laser reliability qualification (e.g., Telcordia GR-468) and/or laser packaging experience
