OPTICAL_PHYSICS · ROL-0001
Silicon Photonics Design Engineer
Own the layout and simulation of passive and active photonic building blocks — waveguides, couplers, ring resonators and modulators — on a 300mm silicon photonics platform. You will work script-first, in a layout-as-code flow, alongside the process and test teams.

RESPONSIBILITIES
- Design and simulate passive photonic components: waveguides, directional couplers, MMI splitters, ring resonators and grating couplers.
- Translate a physical specification (loss budget, bandwidth, footprint, FSR) into a parameterised cell library.
- Run FDTD and eigenmode sweeps to fix geometry before tape-out, and document the trade-offs you took.
- Build and maintain the test structures that let us separate design error from process variation.
- Work with the layout and verification engineer through DRC/LVS clean-up to a signed-off GDSII.

WHAT WE NEED TO SEE
- Degree in physics, applied physics, electrical engineering or nanotech — or equivalent demonstrated work.
- Working knowledge of guided-wave optics and at least one electromagnetic solver.
- Ability to script your own design flow rather than clicking through a GUI.
- Comfort reading a process design kit and reasoning about what it does not let you build.
ADVANTAGEOUS
- Tape-out experience, even a shared multi-project wafer run.
- Familiarity with modulator physics and travelling-wave electrode design.
- Bench experience measuring insertion loss and spectrum.
