Specialist, OBD IUMPR & Performance Requirements Engineer

Here you don't just design vehicles, you shape the future of the road. Our Engineering team is where bold ideas meet rigorous execution, building machines that are as durable and capable as the people who drive them. You'll work shoulder‑to‑shoulder with brilliant minds across disciplines, turning complex challenges into elegant, scalable solutions that meet the highest standards of safety, performance, and user experience.

This is a place where your fingerprints are found on metal – where what you design gets built, driven, and remembered. If you're hungry to engineer something that matters, this is where that ambition finds its highest gear.

• Define and maintain OBD requirements related to IUMPR performance
  , ensuring compliance with regulatory expectations for monitor execution frequency and completeness
• Develop requirements for monitor enable conditions, execution criteria, and denominator/numerator logic
  , ensuring robust behavior under real‑world driving conditions
• Ensure that OBD monitors achieve sufficient in‑use performance ratios across all relevant operating scenarios, including varying drive cycles, environmental conditions, and vehicle states
• Collaborate with system, calibration, and software teams to design monitor strategies that maximize execution frequency while maintaining technical correctness and robustness
