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. As a wafer level test engineer, you will: Take responsibility and ownership of the operation, performance, and maintenance of Xanadu’s high-volume testing setups, ensuring these are at high utilization with support from testing operators.

Make test plans, manage equipment allocation and train operators. Ensure all test results are securely captured, properly stored, and traceable back to specific wafers, die locations, test scripts, measurement setups and equipment configurations. Identify and propose improvements to testing workflows and qualification procedures to enhance efficiency, repeatability and reproducibility.

Serve as the point of contact for tool failures that exceed operator capabilities (e.g., diagnosing software bugs in the test scripts or troubleshoot hardware related issues). Maintain strong cross-functional communications with measurement requesters to ensure clear alignment on test priorities and delivery timeline for results. Engage in test equipment development activities, alongside our instrumentation experts.
