The posting

At IBM Research, we are the innovation engine of IBM. Exploring what’s next in computing and shaping the technologies the world will rely on tomorrow. From advancing AI and hybrid cloud to pioneering practical quantum computing, we anticipate challenges and unlock new opportunities for clients, partners, and society. Working in Research means joining a team that accelerates discovery at the intersection of high-performance computing, AI, quantum, and cloud. You’ll collaborate with leading scientists, engineers, and visionaries to push boundaries and turn ideas into reality. With a culture built on curiosity, creativity, and collaboration, IBM Research offers the opportunity to grow your career while contributing to breakthroughs that transform industries and change the world.

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.

  • 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.
  • 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).

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
