# Quantum System Performance Scientist

- **Company:** IBM
- **Location:** Yorktown Heights, NY, United States
- **Contract:** Permanent contract
- **Skills:** Data Analysis, Python (Programming Language), Software Coding
- **Published:** October 3, 2026
- **Apply:** https://dejobs.org/x/x/F265AFA045F04E508A9F4FA9D1922A78/job/

## About the Role

The successful candidate will join a team of scientists and engineers in a highly collaborative effort to optimize the performance of IBM Quantum systems for large-scale quantum experiments. The role involves identifying performance gaps through the design and analysis of quantum measurements, and developing or enhancing calibration sequences for superconducting (SC) quantum processors. This position requires close collaboration with cross-functional teams, including analog and digital signal engineers, experimental and theoretical physicists, and software developers, in a fast-paced environment. Strong communication skills, technical rigor, and a high sense of ownership are essential.

Required technical and professional expertise

 * Strong track record in quantum measurement techniques, with working knowledge in characterizing:
 * Coherence times, spectral frequencies, coupling strengths
 * Coherent vs. incoherent errors and processes
 * Using Error-amplification or related techniques
 * Excellent coding skills in Python, including for data analysis.
 * Experience with RF/microwave characterization or design, such as:
 * device-level, PCB-level, or wiring-level design and/or measurement.

Preferred technical and professional experience

 * Experimental research experience with superconducting qubits, especially in measurement and/or characterization.
 * Experience using agentic AI coding tools.
 * Cryogenic RF/microwave design and characterization experience.
 * Experience optimizing quantum device performance and calibration.
 * Experience with dynamic decoupling sequences.
 * Experience automating measurements through software.
 * Experience working with theorists.
 * Experience with simulation of:
 * Hamiltonian dynamics and/or
 * Open-quantum-system dynamics.
 * Experience analyzing or simulating analog electrical-circuit response.
 * Experience with quantum circuits (e.g., Qiskit).
