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. We’re changing that.At our Detroit headquarters, we combine the industrial DNA of America’s manufacturing heartland with the speed, intelligence, and precision of Silicon Valley. Our AI-driven platform tackles the hardest problems in geometry, process planning, and fabrication, collapsing production timelines from months to days and soon, minutes. We don’t just build software; we run a fully operational factory where our technology produces production-grade tooling every week, enabling tight feedback loops and rapid iteration.Backed by top-tier investors, we’re restoring speed, flexibility, and capability to the American industrial base. Our mission is to make manufacturing as agile and scalable as the digital world, and in doing so, rebuild the infrastructure of the physical economy.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 DoDevelop and implement simulations for thermal, structural, and material processesValidate models against physical test data and real production outcomesWork with mesh and CAD data to define simulation-ready geometry representationsIntegrate solvers and workflows into cloud/on-prem hybrid infrastructureCollaborate with geometry and software teams to inform design and automation logicOptimize simulation runtimes for performance and fidelityWhat We’re Looking ForMinimum Qualifications5+ years of experience with physics-based simulation (FEA, CFD, or related)Deep understanding of mechanical behavior, contact mechanics, heat transfer, or fluid flowExperience 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 meshesStrong ability to reason from first principles and validate models against the real worldBonus PointsExperience in manufacturing or product design contextsFamiliarity with GPU acceleration or distributed computeBackground in simulation automation or surrogate modelingIntegration of simulation results into design or optimization systemsHow We WorkFast iteration: We deploy code daily and validate it in the factory every weekFactory-first mindset: Engineers spend time on the shop floor to understand the real-world impact of their workLow ceremony, high ownership: We value well-written design docs, tested code, and real results — not meetingsCollaborative culture: Geometry, AI, and robotics teams are tightly integrated and co-develop the product togetherBenefitsCompetitive salary and generous equity packageFull medical, dental, and vision coverage for employees and dependents401(k)PTO with a 15-day minimumQuarterly team travel to DetroitVisa support for TN, E‑3, and O‑1 candidatesHardware stipend and on-site prototype lab access
