Job Description

Photonics Fabrication and Design Engineer

Boulder, Colorado, United States (On-site)

On-site | Boulder, CO

$140K–$180K base + equity

I’m working with a well-funded deep-tech startup developing a new integrated-photonics platform for advanced computing applications.

They are hiring a Photonics Fabrication and Design Engineer to own hands-on device fabrication, process development and design iteration. This is a fabrication-first position for someone who wants to personally develop hardware rather than work exclusively through external foundries.

You’ll work on problems such as:

• Owning microfabrication and nanofabrication runs
• Developing and stabilizing repeatable process flows
• Troubleshooting lithography, etch, deposition and integration issues
• Performing failure analysis and correlating process changes with device performance
• Fabricating integrated photonic and related semiconductor devices
• Designing passive photonic components and test structures
• Preparing layouts for fabrication
• Supporting optical characterization and design iteration
• Improving process yield, repeatability and documentation
• Contributing to emerging integration and packaging approaches.

Looking for engineers who have:

• Personally owned cleanroom fabrication runs for integrated photonic or closely related devices
• Hands-on experience with lithography, dry etching, deposition and process development
• Diagnosed failed runs and implemented process improvements
• Worked with passive components such as waveguides, couplers, splitters, tapers or mode converters
• Used electromagnetic simulation tools such as Lumerical, Tidy3D or similar
• Used layout and DRC tools such as KLayout, Luceda, Cadence or related platforms
• The ability to work independently in a shared cleanroom environment
• Strong communication and experimental documentation skills.

Experience with SiN, silicon photonics, superconducting devices, hybrid integration, bonding, foundry transfer, PDK development or process-of-record creation would be particularly relevant.

The role can broaden into photonic design and testing over time, but the immediate priority is someone capable of taking direct ownership of fabrication and process development.

This is an opportunity to establish a foundational technical capability and help move a new photonic platform from early devices toward integrated hardware.

Worth a confidential chat?
