Product Engineer, Test & Measurement

Hyper Light is at the forefront of the commercialization of thin‑film lithium niobate (TFLN) integrated photonics, enabling high‑performance, scalable optical components across AI, datacom, hyperscale computing, quantum computing, sensing and beyond. Founded in 2018 and backed by leading venture capital, we have built a team and platform focused on real‑world mass deployment of TFLN photonics technology.

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 to deploy the technology quickly and effectively. We partner with customers and suppliers from conceptualization, design, and prototyping stages through mass production to ensure smooth and rapid deployment of TFLN photonic technology.

Our diverse team thrives on challenges and is united by a shared commitment to excellence, integrity, innovation, collaboration and pragmatic solutions. We take pride in tackling complex challenges with curiosity, humility, and a deep sense of care for one another.
