This role exists to design, simulate, tape-out, and mature PICs (and associated lasers and photodetectors), closing the loop between theory, simulation, and large-scale experimental data.
This is not a “paper PIC” role.
It is about making photonics inevitable in real products.
The Role As a Photonics Design & Simulation Engineer, you own PIC design from first principles through tape-out and data-driven refinement.
You will work in a highly automated test environment where data is abundant.
Your job is to:
design quickly
simulate intelligently
update models ruthlessly based on measurement
Iteration speed and convergence matter more than elegant one-off designs.
What You’ll Do - Design, layout & simulation
Design PIC components and circuits from scratch
Perform layout using KLayout (scripted layout strongly preferred)
Run and interpret DRC (foundry specifics can be taught)
Simulate PICs using tools such as:
Lumerical MODE / FDTD / INTERCONNECT
COMSOL Wave Optics
Zemax or equivalent is a bonus
Closing the loop (core responsibility)
Correlate simulation results with wafer-scale and lot-scale measurements
Update models based on real data, not idealised assumptions
Use justified correction ("fudge") factors where appropriate
Balance simulation speed versus accuracy deliberately
Treat simulation as a hypothesis generator, not truth
Data, automation & coding
Analyse large experimental datasets with strong statistical discipline.
Write substantial
Python
for:
analysis
automation
model validation
reporting
Maintain high standards for design and data versioning, traceability, and reproducibility
Production mindset
Design for yield, fabrication tolerance, and scalability
Work closely with process, metrology, and foundry teams
Contribute to faster, more predictable tape-outs
Required Background You must have:
Deep experience in PIC design and simulation
Completed multiple PIC tape-outs (preferably at a known foundry)
Personally closed the loop between simulation and measurement
Excellent
Python
coding and data analysis skills
Strong grasp of statistics and variation across wafers and lots
Experience with lasers and photodetectors is strongly preferred.
Who This Role Is For
Designers who move fast and iterate
Engineers frustrated by slow, fragile PIC workflows
People who believe photonics hasn’t scaled due to execution, not physics
Engineers with high standards and attention to detail
Builders focused on outcomes, not speculative designs
What This Role Is Not
a theory-only or research-only role
a “hero device” design position
a simulation-first, measurement-second job
a place for spreadsheet- or GUI-only workflows
What Success Looks Like After 6–12 months:
PIC designs converge faster with fewer surprises
Simulation models are trusted because they reflect reality
Components are characterised across wafers and across lots
Designs become measurably more linear, tolerant, and scalable
Tape-outs are faster and more predictable
The organisation trusts photonics data when making decisions
