How we know
It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.
Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Volantis Semiconductor, Inc., so its true age is longer.
Last checked Nov 1, 2026.

About the role
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
