Senior Photonic Design Engineer

Los Angeles, CA (preferred) / Remote

c$240K + Bonus + Equity


We’re hiring a Senior Photonic Design Engineer to lead the design and development of photonic integrated circuits for next-generation optical interconnects in AI data centre environments.

You will own the full PIC lifecycle—from device design and simulation through layout, packaging, PCB integration, and system-level validation—helping deliver robust, production-ready components for high-speed datacom transceivers.

The role sits between device physics, system performance, and manufacturability, working closely with packaging, test, and systems teams to push coherent optical link technology forward.


Key responsibilities

  • Design and optimise active and passive photonic components (modulators, detectors, waveguides, lasers)
  • Run optical, EM, and device-level simulations and interpret results
  • Plan and execute DOEs for device optimisation and yield improvement
  • Develop PIC layouts using industry-standard design tools
  • Perform system-level modelling of optical links using simulated and measured data
  • Support packaging, PCB integration, and assembly of PIC-based systems
  • Define test plans and validation strategies for photonic components
  • Lead reliability, failure analysis, and yield learning activities


Requirements

  • MS or PhD in Electrical Engineering, Physics, or related field
  • 5+ years’ experience in photonic or PIC design for telecom/datacom
  • Experience with optical transceivers (modulators, lasers, photodiodes, passive PICs)
  • Strong understanding of system-level optical link behaviour
  • Hands-on experience with PIC testing, packaging, and qualification
  • Familiarity with photonics simulation and layout tools
  • Ability to work across device, system, and hardware domains


What’s on offer

  • c$240K + Bonus + Equity
  • Full ownership of end-to-end photonic design work
  • High-impact role in AI-focused optical interconnects
  • Fast-moving, deep-tech startup environment
