The posting

About the Role

Periodic Labs is building AI systems that can simulate physical science, verify predictions, and train on the full scientific method. We are looking for a Computational Scientist to build differentiable, accelerator-ready simulations for industrially relevant continuum-physics problems.

You should be equally comfortable with governing equations, solver code, and deep learning. We are open to expertise in any area of continuum-physics, with at least some experience in fluid dynamics. You will work on building simulation capabilities in challenging, data-limited domains requiring a mix of physics-based and empirical approaches.

What You’ll Do

  • Build and extend differentiable solvers for continuum simulation (including but not limited to fluid dynamics), especially multi-scale and multi-physics problems.
  • Implement numerical methods from equations and papers, and diagnose convergence, stability, and modeling failures.
  • Combine simulation with deep learning for surrogate modeling, learned physics, inverse problems, parameter estimation, and optimization.
  • Use automatic differentiation and modern accelerators with JAX or PyTorch to make simulations scalable and trainable.
  • Validate models against experiments, trusted benchmarks, or high-fidelity simulations.
  • Create datasets and evaluations to guide the development of LLMs to accelerate and automate these tasks.

You Will Thrive Here If You Have

  • A PhD or equivalent research experience in applied mathematics, computational science, physics, engineering, computer science, or a related field.
  • Code-level experience building or substantially modifying PDE solvers, numerical methods, or differentiable simulations.
  • Deep expertise in at least one continuum domain, with breadth across domains or a demonstrated ability to learn new physics quickly.
  • Meaningful experience building, training, and evaluating deep-learning models for physical systems.
  • Strong Python and software-engineering skills, especially JAX, PyTorch, Julia, or C++.
  • Experience applying simulation to realistic scientific or engineering problems, not only clean academic benchmarks.
  • A startup mentality: ownership, good judgment under uncertainty, and enthusiasm for building from scratch.

Strong Candidates May Also Have

  • Experience with fluid dynamics plus another continuum domain, or with multiphysics and multiscale modeling.
  • Expertise in adjoint methods, implicit differentiation, differentiable programming, or scientific optimization.
  • Experience accelerating scientific software on GPUs or TPUs.
  • Contributions to scientific open-source software used by others.
  • Experience connecting simulation to experiments, engineering decisions, semiconductors, or autonomous workflows.

Mechanics

  • Minimum education: Bachelor's degree or similar experience
  • Location: Menlo Park, CA
  • Compensation: $250,000-350,000 + equity
  • Visa sponsorship: Yes, we sponsor visas and will do everything we can to assist in this process.

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.
