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
