About the job
HyperLight, located in Cambridge, Massachusetts, develops thin-film lithium niobate (TFLN) integrated photonics for scalable optical components. Since 2018, the company has supported sectors such as AI and datacom infrastructure, hyperscale computing, quantum computing, and sensing. HyperLight’s TFLN Chiplet™ platform enables modular, integrated system design and supports manufacturability for complex applications.
Role overview
The Senior Photonics Process Development Engineer leads efforts to develop, refine, and scale fabrication processes for the TFLN platform. This position involves working directly with customers, especially in quantum computing and other emerging areas, to turn technical requirements into robust, scalable manufacturing processes. The role also manages advanced process node development and coordinates process variations to improve device performance.
What you will do
- Define and optimize next-generation and custom fabrication processes for high-performance TFLN photonic integrated circuits (PICs).
- Collaborate with customers and suppliers to develop processes that meet immediate and future performance needs.
- Coordinate with internal teams in design, testing, and production to manage development tapeouts, oversee production, and support wafer-level testing.
Collaboration and impact
This role involves cross-functional work within HyperLight, including direct interaction with customers and suppliers. The Senior Photonics Process Development Engineer helps shape fabrication strategies for new applications and ensures timely delivery of solutions.
