Specialist, OBD IUMPR & Performance Requirements Engineer

What you'll do

• Shape the future of the road by designing vehicles and ensuring robust diagnostic monitor performance.
• Collaborate with system, calibration, and software teams to design monitor strategies that maximize execution frequency while maintaining technical correctness and robustness.
• 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.
• Identify and mitigate risks related to low monitor execution rates, including constraints from electrified powertrains, thermal limitations, or system dependencies.
• Support the definition of drive cycles, validation approaches, and data evaluation methods to assess IUMPR performance during development and testing.
• Analyze vehicle and HIL/test data to evaluate monitor performance, readiness behavior, and statistical coverage, and identify gaps or compliance risks.
• Ensure alignment between monitor design, readiness requirements, and regulatory expectations, including consistency across diagnostic functions.
• Contribute to regulatory readiness by supporting technical documentation, reporting, and audit preparation related to OBD monitoring performance.
• Partner with architecture and systems teams to ensure IUMPR strategies are scalable and compatible with SDV concepts, including OTA updates and evolving vehicle functionality.
• Continuously improve monitor strategies, requirement quality, and validation methods to ensure best-in-class diagnostic performance.
• Be involved in other related tasks / activities as required.
