## About the role

Lead experimental programs to characterize, calibrate, and optimize two-qubit gates on tunable-coupler devices, from single-pair physics investigations to full-processor deployment. Identify gate-error bottlenecks (e.g., coherent control error, decoherence, leakage, crosstalk, TLS interactions) for single-pair as well as large-scale systems and isolate their physical origin through targeted experiments, benchmarking, and simulation.

## What they're looking for

- PhD in Physics, Applied Physics, Electrical Engineering, or a related field
- Significant hands-on experience calibrating and characterizing two-qubit gates on superconducting quantum devices, direct experience with tunable couplers is a strong plus
- Deep understanding of gate design, pulse engineering, and decoherence mechanisms, with a track record of connecting error diagnostics to concrete fidelity improvements
- Demonstrated ability to independently execute complex experimental efforts from concept to validated result
- Strong Python skills in a scientific context, and comfort building tools that others rely on
- Dogged experimental determination, with the judgment to balance depth of investigation against speed of iteration
