Laser Design Engineer

Location: Remote - SF / Boston / Austin Employment: Full-time Level: — Design our custom lasers and their integration with the wafer-scale interposer. You will contribute to our first- and second-generation custom laser designs, and to their integration with the wafer-scale interposer. Responsibilities • Owning aspects of qualification and ramp up of VCSEL array product line from design and epitaxy through fabrication, testing and packaging at contract manufacturers. • Working with epitaxial wafer vendors and contract manufacturers to ensure epitaxy and mask/fabrication designs can be successfully implemented and repeatably produced. • Working with the electronics, packaging and wafer-scale interposer teams to improve the VCSEL design for the integrated interposer product, balancing density, yield and manufacturability tradeoffs in a novel architecture. • Working with laser team to set technical direction/road map based on integrated interposer needs. • Driving design reviews of VCSEL with other teams Requirements • Deep understanding of VCSEL epitaxy design, fabrication design and process, validation, and qualification • Experience taping out VCSEL epitaxy and mask/fabrication processes • Hands-on experience contributing to an industry-first laser design • Ability to work independently as well as in cross-functional teams including electronics, packaging Nice to have • Experience using outsourced contract manufacturers for large volume production of VCSELs • Experience with high-density VCSEL arrays and VCSEL polarization stabilization • High speed direct modulation laser diode design/test experience • Understanding of sources of process variation and statistical process control for yield improvement • Laser packaging and/or reliability experience
