Senior Process Development Engineer

The ever growing technological advances in computing, communication, and sensing depend on photonics. PINC builds the transformative integrated photonic platform to address these needs and make that future possible. Our proprietary NanoPPLN photonic platform is based on pioneering advancements from the Nonlinear Photonics Laboratory at Caltech.

PINC is an early-stage startup with venture backing from leading financial investors and major global photonics companies.

We are growing quickly and looking for passionate, highly driven, and self-disciplined individuals to join us on this journey, who are excited to push the boundaries of Photonic technologies.

This is an excellent opportunity for people who excel in a fast-paced environment, approach challenges with a “can-do” mindset, and work collaboratively to inspire others while helping to build a strong team around them and with them as we scale the company together.

The Opportunity

We are seeking a Senior Process Development Engineer to join our team in Pasadena to own and advance fabrication processes for PINC's integrated photonic circuit products.
