About Atomic Industries

Atomic Industries is reinventing how the world makes things. From cars and aerospace systems to medical devices and packaging, most physical goods begin life in a mold or are shaped by a manufacturing tool. Producing these tools has always been slow, manual, and dependent on scarce expertise, taking weeks or months. Atomic Industries is changing that. At their Detroit headquarters, they combine the industrial DNA of America’s manufacturing heartland with the speed, intelligence, and precision of Silicon Valley. Their AI-driven platform tackles the hardest problems in geometry, process planning, and fabrication, collapsing production timelines from months to days and soon, minutes. They don’t just build software; they run a fully operational factory where their technology produces production-grade tooling every week, enabling tight feedback loops and rapid iteration. Backed by top-tier investors, their mission is to make manufacturing as agile and scalable as the digital world, rebuilding the infrastructure of the physical economy.

About the Role

As a Simulation Engineer at Atomic Industries, 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 tools that reduce tooling lead times from months to days — and eventually minutes. You will collaborate with software engineers, generalists, and manufacturing experts to deploy simulation pipelines used every day in production. This role suits someone who blends theoretical rigor with strong intuition for real-world behavior.

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 For

Minimum 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: code deployed daily; validated weekly in factory
• Factory-first mindset: engineers spend time on shop floor for real-world impact understanding
• Low ceremony, high ownership: emphasis on well-written design docs, tested code,...
