## Description

* Room temperature electrical testing
 * Dicing
 * Optical inspection
 * Wirebonding of chips inside sample holders

The team is in charge of:

 * operating the tools for the regular delivery of test chips
 * developing/improving new processes (for better quality/leadtime/chip selection…)
 * overseeing its own tools (daily check of the tools, ensuring maintenance schedules are followed, 1 level of troubleshooting)
 * selection, installation and qualification of new tools, As a Test & Characterization Engineer within the Nanofabrication Backend Team, you will play a critical role in validating our fabrication processes, ensuring data reliability, and developing innovative testing methodologies for superconducting qubits. You will contribute to improving wafer and chip performance through rigorous device testing, robust metrology, and collaborative problem-solving across teams.
 * Develop and optimize superconducting qubit testing methods at room and cryogenic temperatures, providing fast feedback to nanofabrication processes and ensuring efficient sorting of chips.
 * Collaborate with design and process integration teams to define and evaluate test structures that improve wafer- and chip-level performance.
 * Ensure accuracy and reliability of equipment metrology, data acquisition systems and inspection equipment.
 * Contribute to the identification, procurement, and validation of new test and metrology equipment for the backend nanofabrication line.
 * Implement continuous improvement plans to enhance testing efficiency, reliability, and throughput.
 * Perform device testing at room and cryogenic temperatures, ensuring accurate and reproducible results.
 * Participate in failure analysis and root cause investigations, helping to close the loop between design, fabrication, and performance.
