We are seeking a Senior Photonics Design Engineer to drive the design and scaling of state-of-the-art passive and active components powering fault-tolerant quantum hardware. Leveraging our custom high-throughput cloud simulation pipelines, you will develop and execute novel component design strategies to achieve unprecedented sub-milli-dB loss targets. You will engage with our Fabrication, Tooling and Test teams to manage complex performance trade-offs, executing sophisticated DOEs, and deploying data-driven analysis to close the design loop from initial concept to high-volume wafer production.
What you’ll be doing:
Design high-performance passive and active photonic components, targeting ultra-low-loss performance
Develop scripted photonic layouts and contribute to multiple tapeouts
Work closely with fabrication, tooling and test teams to optimise designs for wafer-level production
Use DOE, statistical analysis and automated optimisation to improve component performance
Build the feedback loop between simulation, fabrication and experimental data
What they’re looking for:
MSc or PhD in Photonics, Electrical Engineering, Physics or a related field
2+ years of industry experience in photonic design
Robust experience designing passive PIC components and accounting for wafer/fabrication variation
Deep understanding of photonic loss mechanisms and fabrication processes
Solid experience with scripted mask design and layout
5+ photonic tapeouts covering design, layout and analysis
Experience with Git/version control and cooperative engineering environments
Bonus experience:
Active photonic components such as Pockels-effect phase shifters or III-V photodiodes
Photonic foundry processes and reusable/version-controlled PDK building blocks
DOE, design centering and wafer-level optimisation
JMP or similar statistical analysis tools
Automated optimisation techniques such as Bayesian, particle swarm or adjoint optimisation
DRC/LVS, OPC/bias correction and mask data preparation
Electro-optic co-design with TIAs and electrical drivers
