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, 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 Photonic Test Engineers who are highly motivated individuals and who enjoy problem solving. These positions will focus on measurement, test and analysis on wafer level and device level. Join us to make a real-world impact in a fast-paced, collaborative and high-growth environment.
Key Responsibilities
- Define and implement die-level and wafer-level test solutions in collaboration with design and product teams.
- Develop production test solutions for PIC components to ensure manufacturability and scalability.
- Develop and execute design verification tests, analyze results, and provide feedback to improve device performance.
- Optimize and standardize test and analysis methodologies to improve repeatability and accuracy.
- Bring up, manage, and operate automated wafer-level test (WLT) probers and chip level handlers for PIC devices, including passive and active optical and RF components.
- Perform routine setup calibrations and ensure quality control throughout the test process.
- Identify and mitigate test challenges to ensure timely, efficient execution of large-scale technical projects.
- Take ownership of collecting high-quality measurement data and preparing measurement reports for optical, electrical, and electro-optical tests.
- Analyze test results, perform Gauge Repeatability and Reproducibility (GR&R) studies, troubleshoot issues, and recommend improvements.
- Document test procedures, results, and technical reports to maintain a comprehensive knowledge base.
Requirements
- Bachelor's or higher degree in Electrical Engineering, Photonics, Physics, or a related field.
- 2–5+ years of experience testing and characterizing photonic or semiconductor devices (fresh graduates with strong academic or project experience in photonics/semiconductor testing are also encouraged to apply).
- Solid technical understanding of, and ability to perform, optical, RF, or electro-optic measurements.
- Strong proficiency in Python programming is required, with hands-on experience building test automation scripts and instrument interfacing/control (e.g., SCPI, VISA, GPIB).
- Strong analytical and problem-solving skills, with close attention to detail, diligent note-taking, and precise report writing.
- Knowledge of semiconductor fabrication processes and photonics principles is a plus.
- Ability to work well in a team environment and participate in cross-functional activities.
- Experience interfacing with or managing foundries or OSATs is a plus.
- Proficient in English and Mandarin, as the role requires frequent collaboration with our global team.
Benefits
- Competitive market-based compensation and benefits
- Professional growth and mentorship opportunities
