Layout & Design Engineer - SNSPDs (Superconducting Nanowire Single Photon Detectors) 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. In this role, you will help develop our internal PDK, with a focus on complex multiplexed multi-pixel detector arrays.

You will also lead mask design for fabrication process optimization, bridging the gap between simulation and experiment by designing advanced test structures and production tape-outs. This position offers unique design experience with state-of-the-art foundry processes through Xanadu's 300mm fabrication partners and rapid 100mm in-house development. Design and execute GDS mask layouts for test structures and production tape-outs, ensuring high-quality fabrication outputs.

Perform device-level simulations and develop automated pipelines to integrate design environments with simulation tools. Regularly interact with the Xanadu Fabrication Engineering team to align design strategies with fabrication capabilities and constraints. Other simulation or computational projects that aligns with the hire's expertise Drive improvements in key SNSPD performance metrics through layout optimization and innovative design strategies.

MSc or PhD in Engineering, Science, or related field, with 2+ years of experience in an industrial setting Expert-level experience with scripted photonic mask design/layout with one or more of the following tools: gdsfactory, ipkiss3, Virtuoso,



OptoDesigner, or similar tools. Expert-level knowledge and experience in performing physical verification with homemade and/or foundry-provided codes, including DRC (design rule check) and LVS (layout versus schematic) to ensure manufacturing compliance and netlist integrity Experience working in a team-oriented team-based development environment, preferably using version control systems such as Git Experience collaborating with internal teams and external partners across process integration, packaging, and fabrication Experience using Python for component design, simulation, layout, and data analysis Strong attention to detail and a rigorous, data-driven approach to problem solving Expertise in layout techniques that account for fabrication effects, such as lithographic rounding, OPC/bias correction, and material non-uniformity, to optimize component performance. 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. We are committed to meeting the needs of all individuals and support a barrier-free workplace. ai .
