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, 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 industry, to empower humanity to the next level. We 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.
Our growing team is looking for a
Senior / Staff Photonic Test Development Engineer. This person will develop and drive execution of cutting-edge wafer-level measurements on our photonic integrated circuits. In close collaboration with our external test partners, this hire will build scalable, automated, and precise test systems that allow us to characterize every chip we make. The person in this role will be a key member of our small team, responsible for building new systems and delivering mission-critical feedback about the performance of our products.
Join us to make a real-world impact in a fast-paced, collaborative and high-growth environment.
Responsibilities:- Own and advance chip-level test and characterization for photonic integrated circuits used in datacenter transceivers.
- Become the technical owner of internally developed photonic test stations, responsible for their operation, calibration, qualification, and continuous improvement.
- Develop, maintain, and extend automated test infrastructure for optical and electrical device characterization.
- Design and implement improvements to test hardware and software, including opto-mechanical fixtures and test automation.
- Qualify test systems for DVT and reliability testing, and ensure robust, repeatable measurement performance using statistical methods.
- Analyze test data and generate clear reports for product, design, and fabrication teams.
- Proactively identify opportunities to improve device performance, test capability, and measurement quality, and close the loop with cross-functional partners.
Requirements- PhD or MS in Electrical Engineering, Physics, Photonics, or a related field, or equivalent industry experience.
