Senior Photonics Design Engineer | Quantum Technology 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 - Strong experience designing passive PIC components and accounting for wafer/fabrication variation - Deep understanding of photonic loss mechanisms and fabrication processes - Strong 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
