Senior Photonics Process Engineer

HyperLight is at the forefront of the commercialization of thin‑film lithium niobate (TFLN) integrated photonics - a material and process technology that is enabling high‑performance, scalable optical components across AI/datacom infrastructure, hyperscale computing, quantum computing, sensing, and more. Founded in 2018 and backed by leading venture capital, we've built a team and a platform focused on real‑world mass deployment of TFLN photonics technology. At the core of our work is the TFLN Chiplet™ platform — a modular, integrated architecture designed for scalability, manufacturability, and seamless integration into complex systems. It offers a rare combination of extraordinary performance and industrial readiness, enabling system developers across applications to deploy the technology fast and ready. We partner with our customers and suppliers from conceptualization, design, and prototyping phases, all the way through mass production to ensure smooth and rapid deployment of TFLN photonic technology. If you are interested in pushing the limits of integrated photonics devices and revolutionizing their applications through hardware and process innovation, we are looking for you to join HyperLight's growing team as a Senior Photonics Process Development Engineer . This role bridges fabrication process development for our emerging applications customer market with the opportunity for direct customer interaction. We are seeking highly motivated individuals who enjoy problem solving and will thrive in a collaborative environment. Join us to make a real‑world impact in a fast‑paced, collaborative, and high‑growth environment! As a Senior Photonics Process Development Engineer , you will be a key player in driving the development, optimization, and scaling of fabrication processes on the TFLN platform, working closely with customers from quantum computing and other emerging applications to understand their needs and translating them practically to scalable fabrication processes. You will take ownership of advanced process node development, manage and execute complex process variations for performance improvement, and ensure that customer needs are met with timely execution.
