About the Team
The Product Design Simulation team is responsible for redefining how we design and engineer hardware. By combining advanced multiphysics simulation with machine learning, we accelerate development, optimize performance, and enable breakthrough products. Our work ensures that design decisions are informed by computational insight and validated against real-world performance.

About the Role
OpenAI is looking for a Simulation Engineer to join our Product Design Simulation team. As a Simulation Engineer, you will use your expertise in mechanics, CFD, and electromagnetics—as well as ML-driven modeling approaches—to help shape the next generation of hardware. You’ll thrive at the intersection of simulation, machine learning, and real-world design, pushing the boundaries of what’s possible through computational intelligence.

This role is based in San Francisco, CA. We use a hybrid work model of 4 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

• Build and run multiphysics models incorporating structural FEA, CFD, and electromagnetic simulations

• Apply machine learning techniques to accelerate workflows, perform surrogate modeling, automate design space exploration, and extract insights from simulation and test data

• Partner with design, test, and hardware teams to define multi-domain performance requirements and real-world load cases

• Validate models through testing and improve prediction accuracy through hybrid physics–ML approaches

• Contribute to the development of scalable, ML-integrated simulation frameworks for faster and smarter decision-making

You might thrive in this role if you:

• Hold an MS or PhD in Mechanical Engineering, Applied Physics, Aerospace Engineering, or a related field

• Have deep expertise in FEA and multiphysics workflows, especially in coupled mechanical–thermal–electromagnetic problems

• Bring hands-on experience applying ML techniques (e.g., regression models, neural networks, surrogate modeling) to simulation or engineering datasets

• Are proficient with tools such as Abaqus, ANSYS, COMSOL, JMAG, and ML libraries like scikit-learn, TensorFlow, or PyTorch

• Possess strong programming/scripting skills (Python, MATLAB) for workflow automation and ML integration

• Have a solid understanding of materials, product design, and real-world loading conditions

• Communicate and collaborate effectively across engineering and data science teams
