Integrated Photonics Product Engineer

Hyper Light 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 beyond. Founded in 2018 and backed by leading venture capital, we have 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.

We believe our platform is the key, in the golden age of integrated photonics, to empower humanity to the next level. We have assembled a world‑class team covering engineering, business, and operations. We believe in the power of integrity, innovation, collaboration, and pragmatic solutions. Our diverse team thrives on challenges and is united by a shared commitment to excellence. We take pride in tackling complex challenges with curiosity, humility, and a deep sense of care for one another.

At Hyper Light, our people are our greatest asset, and we manifest that by empowering our team in our interactions and business decisions. Our Packaged Modulator Business Unit is looking for an Integrated Photonic Product Engineer
