About the RoleAs 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.
You'll collaborate with software engineers, generalists, and manufacturing experts to deploy simulation pipelines used every day in production. This role is ideal for someone who blends theoretical rigor with a strong intuition for how things behave in the real world.
What You'll Do- Develop and implement simulations for thermal, structural, and material processes
- Validate models against physical test data and real production outcomes
- Work with mesh and CAD data to define simulation-ready geometry representations
- Integrate solvers and workflows into cloud/on-prem hybrid infrastructure
- Collaborate with geometry and software teams to inform design and automation logic
- Optimize simulation runtimes for performance and fidelity
What We're Looking ForMinimum Qualifications- 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
Bonus Points- Experience in manufacturing or product design contexts
- Familiarity with GPU acceleration or distributed compute
- Background in simulation automation or surrogate modeling
- Integration of simulation results into design or optimization systems
How We Work- Fast iteration: We deploy code daily and validate it in the factory every week
- Factory-first mindset: Engineers spend time on the shop floor to understand the real-world impact of their work
- Low ceremony, high ownership: We value well-written design docs, tested code, and real results - not meetings
- Collaborative culture: Geometry, AI, and robotics teams are tightly integrated and co-develop the product together
Benefits- Competitive salary and generous equity package
- Full medical, dental, and vision coverage for employees and dependents
- 401(k)
- PTO with a 15-day minimum
- Quarterly team travel to Detroit
- Visa support for TN, E-3, and O-1 candidates
- Hardware stipend and on-site prototype lab access
