Senior Photonics Design Engineer | Quantum TechnologyWe 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 performanceDevelop scripted photonic layouts and contribute to multiple tapeoutsWork closely with fabrication, tooling and test teams to optimise designs for wafer-level productionUse DOE, statistical analysis and automated optimisation to improve component performanceBuild the feedback loop between simulation,



fabrication and experimental dataWhat they're looking for:MSc or PhD in Photonics, Electrical Engineering, Physics or a related field2+ years of industry experience in photonic designStrong experience designing passive PIC components and accounting for wafer/fabrication variationDeep understanding of photonic loss mechanisms and fabrication processesStrong experience with scripted mask design and layout5+ photonic tapeouts covering design, layout and analysisExperience with Git/version control and team-oriented engineering environmentsBonus experience:Active photonic components such as Pockels-effect phase shifters or III-V photodiodesPhotonic foundry processes and reusable/version-controlled PDK building blocksDOE, design centering and wafer-level optimisationJMP or similar statistical analysis toolsAutomated optimisation techniques such as Bayesian, particle swarm or adjoint optimisationDRC/LVS, OPC/bias correction and mask data preparationElectro-optic co-design with TIAs and electrical drivers #J-18808-Ljbffr
