CAD/PDK Engineer

The Role

This is a software and EDA role at the center of a Silicon Photonics company. If you've worked with CAD or EDA tooling, done mask layout, or verification infrastructure in any semiconductor domain — or you're a strong Python engineer who wants to work close to silicon — we'd like to talk. Familiarity, or a strong interest, with optics or photonics preferred.

Working at the hub of the wheel that is OpenLight’s technology, you will build and maintain the software that turns photonic chip designs into manufacturable mask data. As a key member of OpenLight's Design Enablement team, you'll own the automation behind our process design kit (PDK), our mask build flows, and our physical verification infrastructure — the tooling that we rely on every day.

What You Will Do

• Develop and maintain automated mask build workflows that assemble PIC designs into GDS artwork, reproducibly and on schedule

• Build and release the OpenLight PDK: device libraries, parameterized cells, compact models, and symbol/schematic views across our EDA platformsOwn physical verification infrastructure

• Stand up CI/CD pipelines, regression suites, and automated QA to maintain a robust PDK and mask release process

• Partner with EDA vendors to bring up and validate our PDK on their platforms

• Work alongside process engineers, device designers, and PIC Architects to turn manual, error-prone steps into automated workflows

• Monitor for quality escapes, perform root cause analysis, and drive the improvements that prevent recurrence

Your Background Includes

• B.S. or M.S. in Electrical Engineering, Computer Science, Applied Physics, or a related discipline — or equivalent practical experience

• Strong Python skills and solid software engineering fundamentals

• Experience with version control, CI/CD pipelines, and Agile development practices

• Exposure to EDA tool flows or their scripting interfaces — for example SKILL, Tcl, Synopsys ICV, KLayout, IPKISS, or GDSFactory — or a demonstrated ability to pick up domain tooling quickly

• Strong problem solving, communication, organizational, and interpersonal skills

About OpenLight
