Modeling and Simulation Engineer, Thermo-Mechanical

About The Role:

We are seeking a Modeling and Simulation Engineer to join our growing AI and Modeling & Simulation team. The ideal candidate has experience developing and deploying mathematical and numerical models across multiple coupled physics domains. In this role, you will identify the critical attributes of existing manufacturing systems and future machine concepts, then use those insights to build, simulate, and deploy parameterized models that support machine design and optimization.

To succeed in this role, you should have experience with multiscale and multiphysics modeling and be comfortable using simulation tools such as COMSOL, Ansys, or similar platforms. You should also have a strong foundation in structural mechanics and thermal effects. Familiarity with other simulation domains, such as CFD (computational fluid dynamics) and robotic kinematics is a plus.

This is an excellent opportunity for someone with a track record of building high-quality, validated multiphysics models and who is excited to apply those skills to support the development of new classes of devices manufactured at scale on Atomic’s platform. The ideal candidate thrives in a collaborative environment and is effective at documenting, communicating, and presenting technical work.

What You'll Do

• Identify critical system attributes and develop computational models for current and future manufacturing machines, with an emphasis on structural and thermal.
• Define figures of merit, boundary conditions, and operating conditions based on system requirements and cross-functional input.
• Build and deploy multiphysics simulations, including thermal and mechanical models, using finite element methods for both steady-state and dynamic analyses.
• Deliver executable computational models that support sensitivity analysis, design exploration, and optimization.
• Propose validation experiments and use experimental results to calibrate, validate, and improve models.
• Document simulation methods, assumptions, and validation results, and communicate findings clearly to the broader team.
• Collaborate cross-functionally with prototype engineers, designers, and AI engineers.

What You’ll Need:

• 4+ years of hands-on experience in multiphysics modeling and simulation following completion of a bachelor’s degree (or recent PhD).
• Strong foundation in multiphysics simulation, with particular depth in structural mechanics (including the dynamics) and thermal analysis (e.g., thermoelasticity).
• Programming experience, especially in Python, and experience automating simulation workflows for design and optimization.
• Experience with COMSOL and/or Ansys; experience with Abaqus, Siemens tools, or related software is a plus.
• Strong written and verbal communication skills, with the ability to work independently and collaboratively.
• Resourceful, flexible, and adaptable approach to technical work.
• Bachelor’s, master’s, or PhD in engineering, physics, or a related field.

Bonus points for:

• Experience with other modeling domains such as CFD and robotic kinematics
• Experience with thermal and mechanical contact modeling for industry applications.
• Experience with CAD tools such as Onshape, Fusion 360, SolidWorks, NX, or similar.
• Experience with data analysis and visualization tools such as JMP, MATLAB, pandas, or matplotlib.
• Industry experience with product development processes such as Agile or similar frameworks.
