Founding Process Engineer

Overview We are a venture-backed deep tech startup commercializing novel InP-based high-power photonic crystal lasers (PCSELs). We're looking for our first Process Engineer who will own the full PCSEL fabrication process, develop new device flows that push yield and performance, and lead the fab behind our next generation of semiconductor lasers. Responsibilities Drive end-to-end PCSEL device fabrication.

Implement high-yield dielectric, metal, and direct wafer bonding flows.

Lead photolithography process development for photonic crystal patterning.

Develop and tune dry and wet etch processes for III-V optical material stacks.

Establish process control and statistical monitoring for fabrication repeatability.

Debug and iterate processes quickly in a fast-moving environment.

Qualifications

• M.S. or Ph.D. in Electrical Engineering, Materials Science, Physics, or equivalent hands-on experience.

• Demonstrated III-V photonic device fabrication proficiency.

• Strong experience with photolithography, wet and dry etching, thin-film deposition, wafer bonding, and metrology (AFM, SEM, TEM, etc.).

• Comfortable owning ambiguous problems in a startup environment.

• Strong written and verbal communication skills with a collaborative working style.

• Preferred: Experience with the design and simulation of III-V epitaxial structures and semiconductor lasers.
