Integrated Photonics Design Engineer, Device Components

Hyper Light is at the forefront of the commercialization of thin‑film lithium niobate (TFLN) integrated photonics—a material and process technology enabling high‑performance, scalable optical components across AI/data‑com 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 quickly 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 to empowering humanity in the golden age of integrated photonics. Our diverse team thrives on challenges and is united by a shared commitment to excellence, integrity, innovation, collaboration, and pragmatic solutions.

Our growing team is looking for an Integrated Photonics Design Engineer
. We have several open positions with different seniority levels and focuses, including passive optical component design, active component and modulator design, and product design.

As part of your responsibilities, you will:

• Collaborate with product teams and customers to define requirements for device components.
• Own the end‑to‑end design and delivery of high‑performance, robust device components such as fiber couplers, optical taps, optical crossings, thermo‑optic phase shifters, photodiodes, and high‑speed electro‑optic modulators.
• Simulate component designs using FEA tools like Lumerical, Tidy3D, HFSS, CST, and COMSOL.
• Develop and perform rigorous measurement techniques to assess component performance.
• Analyze measurement and simulation data for performance and robustness.
• Collaborate to improve our fabrication processes for optimal device performance.
• Serve as a technical expert within Hyper Light to guide our engineering decisions and technical roadmap.

• Either 5+ years of relevant work experience or an advanced degree (M.S. or Ph.D.) in Electrical Engineering, Physics, or a related field.
• Strong expertise with passive and/or active photonic device component design, including hands‑on development of multiple successful designs.
• Strong expertise in finite element analysis of PIC components using tools like Lumerical, Tidy3D, COMSOL, Synopsys Opti Designer, etc.
• Extensive hands‑on experience performing measurements to characterize photonic integrated circuits using instruments like swept lasers, fiber alignment stages, VNAs, BERTs, oscilloscopes, etc.
• Extensive experience with data analysis and statistical methods such as design of experiments using tools like JMP or Python.
• Demonstrated record of innovation and achievement, e.g., product designs, publications, or patents.
• Familiarity with the entire photonic integrated circuit engineering process, including simulation, layout, fabrication, test, and device operation.
• Excellent organizational and communication skills.
• Comfortable working with cross‑disciplinary teams.

• Competitive market‑based compensation (Salary range $120,000 – $225,000).
• Comprehensive health coverage, including medical, vision, and dental plans for individuals and families.
• 401(k) retirement plans with employee matching.
• Paid parental leave.
• Life and disability insurance.
• Commuter benefits and subsidies.
• Professional growth and mentorship opportunities.
