Xanadu’s mission is to build quantum computers that are useful and available to people everywhere. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems and literally change the world. We are seeking a Senior Photonics Design Engineer to drive the design and scaling of state‑of‑the‑art passive and active components powering Xanadu’s future 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, execute sophisticated designs of experiments, and deploy data‑driven analysis to close the design loop from initial concept to high‑volume wafer production. MSc or PhD in Engineering, Science, or related field, with 2+ years experience in an industrial setting Deep experience with scripted photonic mask design and layout Participated in 5+ tapeouts covering design, layout and analysis Experience working in a cooperative team‑based development environment,
using version control systems such as git turned designs into version‑controlled building blocks Understanding of the concepts of "Design of Experiments" and "Design Centering" applied to wafer‑level optimization of photonic components Performed statistical analysis on wafer‑level data using tools like JMP Incorporation of fabrication processes effects such as lithographic rounding, OPC/bias correction and material non‑uniformity into component optimization Experience developing design rule checks (DRC) and layout vs schematics (LVS) scripts Experience developing custom filler patterns and mask data preparation Performed electro‑optic co‑design of active devices such as phase shifters and photodiodes with TIAs and electrical drivers The base salary range is 120,000 – 170,000 CAD. You will also be eligible for equity and benefits. They are fundamental and lay the foundation for culture at Xanadu. We are committed to building an inclusive, safe, and equitable culture and fostering an environment where our employees feel included, valued, and heard.
