## About the role

As a Simulation Engineer at Atomic, you will develop high-fidelity models that capture the physics and constraints of real-world manufacturing processes. From thermomechanical behavior to material flow and force distribution, your work will power the tools that reduce tooling lead times from months to days — and eventually, minutes.

## What they're looking for

- 5+ years of experience with physics-based simulation (FEA, CFD, or related)
- Deep understanding of mechanical behavior, contact mechanics, heat transfer, or fluid flow
- Experience with commercial or custom solvers (Ansys, Abaqus, COMSOL, in-house)
- Proficiency in Python and/or C++
- Familiarity with geometry formats like B-rep, STL, and volumetric meshes
- Strong ability to reason from first principles and validate models against the real world
