Role summary

The Laser Test Engineer will develop and qualify testing procedures for custom lasers, scaling them for mass production. This role involves owning the development and implementation of testing and reliability procedures for laser designs and their integration with wafer-scale interposers. Responsibilities include defining test plans, characterizing prototype devices, managing test data, designing and maintaining test systems, and ensuring the reliability of VCSELs and overall systems. The ideal candidate has deep hands-on experience with semiconductor laser testing, characterization, validation, and reliability, along with proficiency in designing prober systems, test fixtures, and automation software.

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
