IonQ is developing the world's first fully-expressive, full-stack quantum computer based on trapped ion technology. We are pushing past the limits of classical physics and current super computing technology to unlock the staggering potential of the quantum realm. Quantum computing is poised to reshape medicine, materials, simulation, and much more.

From modeling noise and system design, to analyzing experimental results, to compiling quantum circuits, computational physics is an essential part of our entire quantum computing platform.  We're looking for physicists or engineers with strong high-performance computing experience. At least some advanced mathematics and algorithms experience is essential. Previous computational physics experience is a huge plus, and quantum mechanics knowledge is a ++. We’re looking for people who are self-motivated, self-directed, and innovative, with a great attitude and work ethic.

If this sounds like the right position for you, we encourage you to apply. 


  • Closely collaborating with experimental physicists, quantum circuit designers , and software engineers to build simulations of physical systems
  • Locating code causing computational bottlenecks and making tools to overcome those bottlenecks
  • Contributing to technical documentation

Required Skills/Education:

  • Doctorate or Masters degree in Physics, Computer Science, Mathematics, or relevant field and/or experience of more than 5 years
  • Command-line compilation veteran (gcc/gfortran, icc/ifort, clang, PGI, ...)
  • Experience with CPU parallelization (OpenMP, TBB, or via library)
  • Experience with CUDA or other GPU acceleration framework
  • Success working collaboratively in a team environment

Desired Skills/Education:

  • Expert-level knowledge of Fortran and/or C
  • Expert analysis skills in areas like statistical testing, modeling and general optimization; ML a plus
  • Knowledge of one or more domains of computational physics (PDEs, n-body, large-dimension integration, stochastic systems, ...)
  • Exposure to quantum physics and/or quantum information science
  • MPI or other multiprocessing scheme
  • Performance profiling
  • C extension libraries (eg, Python, Matlab)
  • Working knowledge of Linux
