Xanadu’s mission is to build useful quantum computers. We are a team of learners, innovators, and problem solvers, creating technology that has never been built before. As a Photonics Test Engineer, you will join our Test and Measurement team to build the software that drives the analysis and measurement of on‑chip photonic devices—the foundational building blocks of Xanadu's Fault‑Tolerant Quantum Computer. This role requires both the ability to interpret physical data and models as well as strong software engineering skills. Automating analysis workflows run in jupyter notebooks into cloud deployed pipelines analyzing terabytes of optical data per month. Assigning uncertainties to derived metrics of the analysis. Forecasting uncertainties of proposed experimental designs to measure photonic device performance at bleeding edge precision. Working with hardware engineers and physicists to apply software best practices to their data analysis using the latest tools and models you develop. Debugging unexpected results of analysis at each step in the process – determining if results are due to software failure, experimental failure or physical properties in the device. Interfacing with data engineers to manage data sourcing and maintain data integrity. Developing visualizations and metrics engineers can use to make critical engineering decisions.



While physical intuition and hands‑on lab experience will be valuable, you should be comfortable working in a primarily software role. Experience with python data analysis libraries such as NumPy , SciPy , and pandas . Understanding of python data structures and software design principles. Applicants will be expected to demonstrate proficiency writing python code. Strong foundational understanding of photonics, optical physics, quantum physics, or analogous fields. Bachelor’s degree in Engineering, Physics, or a related field. Master’s or PhD degree in Engineering, Physics, or a related field. ~1+ years of experience in a qualified software development environment. ~ Understanding of the full software development lifecycle, including version control, code review, testing, continuous integration, logging, and documentation. ~ Experience with Bayesian methods or optimization methods in data analysis. ~ They are fundamental and lay the foundation for culture at Xanadu. 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. ai. Note: Xanadu will never ask you for bank account information as part of the interview process. ai.
