Job summary

Zeromatter in the United States is seeking a Physics Simulation Engineer for its Dynamics team. You will build and extend the physics engine powering vehicle, aircraft, drone, and robot simulations, tackling solvers, contact handling, and stability challenges.

The role emphasizes reading research, implementing state-of-the-art methods, and collaborating with controls to meet validation needs. Strong math, software craft, and C++/Rust skills are required.

Qualifications

• Engineering degree or equivalent hands-on experience shipping a physics or dynamics simulation engine.
• Experience in real-time or offline physics/dynamics simulation engines in games, VFX, robotics, or research.
• Strong software engineering practices including clean architecture, testing, code review, and version control.
• Strong intuitive understanding of linear algebra, quaternions, multivariable calculus, and numerical methods.
• Ability to read, understand, and adapt techniques from simulation research papers or production engines.
• Familiarity with numerical time integration for dynamics (e.g. implicit/semi-implicit Euler, symplectic integrators, or constraint-based methods like PBD/XPBD).
• Experience solving large systems that arise in dynamics simulation (PCG, direct solvers, etc.).
• Experience with contact and collision handling in a simulation context.

Responsibilities

• Implement and extend numerical solvers for dynamics simulation that scale to large, contact-rich scenes.
• Develop high-fidelity contact and collision handling, including penetration and friction models.
• Read and implement techniques from state-of-the-art simulation research and production engines.
• Validate new methods mathematically and empirically to ensure fidelity.
• Diagnose and resolve simulation instabilities and profile solver performance.
• Contribute to material/constitutive models and degrees of freedom representations.
• Write documentation and translate complex math for engineers without a physics background.
• Collaborate with controls and characterization engineers to serve validation needs.
