# Electro-Optic Modulator Design 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 beyond. 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 architecture designed for scalability, manufacturability, and integration into complex systems. We partner with our customers and suppliers from concept and prototyping through mass production. We believe in integrity, innovation, collaboration, and pragmatic solutions, and we take pride in tackling hard problems with curiosity, humility, and a deep sense of care for one another. Our growing team is looking for an Electro-Optic Modulator Design Engineer to use RF and optical physics principles to design, optimize, and characterize high-speed electro-optic modulators. These devices are at the core of our platform, and you will own them from end to end. RESPONSIBI
