Role SummaryThe Virtual Vehicle team builds vehicle simulation that engineers across the company rely on as evidence. You will be a core owner of its physics engine: a high-performance, deterministic C++ simulation core for full-vehicle dynamics and subsystem behavior, coupled to production controller software through standard co-simulation interfaces. Your mission is to make it faster, more capable, and provably unchanged where it is already validated - and to set the technical direction for how physics fidelity is chosen, implemented, and verified.
Responsibilities• Own engine performance and numerical robustness, with regression evidence that validated results are preserved.
• Design and implement multi-fidelity simulation so each study runs at the fidelity its question requires.
• Extend vehicle-dynamics and subsystem modeling capability (tires, suspension, driveline, terrain, sensors).
• Own reproducibility and performance standards enforced in continuous integration.
• Set technical direction, document architectural decisions, and mentor engineers.
QualificationsMinimum Qualifications:
• MS/PhD in Mechanical, Aerospace, Computer Engineering, Applied Mathematics, or a related field - or equivalent demonstrated experience.
• 7+ years building performance-critical numerical or simulation software in modern C++ - or an equivalent demonstrated record.
• Strong numerical methods: integration schemes, stiff systems, constraint and contact solvers.
• Profiling and optimization on real workloads; disciplined use of sanitizers and static analysis.
- Experience reasoning about floating-point reproducibility across compilers and platforms.
Preferred Qualifications
- Experience with the internals of a multibody or vehicle-dynamics simulation engine.
- Co-simulation experience (FMI or similar standards).
- Tire and suspension modeling knowledge.
- Open-source contributions to scientific or simulation software.
