Senior Engineer Emissions and OBD Fleet

About the role

Senior Engineer Emissions and OBD Fleet at Hyundai America Technical Center, Inc. (HATCI), supporting the gasoline and hybrid validation fleet team in Superior Township, Michigan. The role is part of the Electrified Propulsion Test & Verification (ePTV) team within the Electrified Propulsion Development division, responsible for verifying pre‑production vehicle emissions calibrations, aftertreatment, and on‑board diagnostics for future ICE and HEV applications targeting LEV IV, Tier 4, SULEV20, and SULEV30 compliance. Reports to the senior manager of ePTV.

Responsibilities

• Responsible for validating emissions compliance, OBD performance, and aftertreatment durability for gasoline, hybrid, and future electrified powertrain programs via mileage accumulation fleet vehicles.
• Define and execute North American emissions durability fleet programs, including vehicle deployment, mileage accumulation, route strategy, durability testing schedules, and overall fleet health management from 0 to 150,000 miles.
• Develop and maintain fleet validation plans to verify compliance with EPA, CARB, LEV IV, Tier 4, SULEV20, SULEV30, and future regulatory requirements throughout the full useful life of the vehicle.
• Lead periodic emissions and OBD evaluations throughout the fleet lifecycle, including tailpipe emissions testing, diagnostic system verification, catalyst aging assessments, and emissions deterioration analysis at defined mileage intervals.
• Analyze emissions deterioration trends relative to certification and engineering development targets, providing technical recommendations and risk assessments to program leadership.
• Lead root-cause investigations for emissions, OBD, catalyst efficiency, drivability, and aftertreatment performance issues identified during durability fleet operation.
• Support development and implementation of corrective actions, calibration enhancements, hardware recommendations, and control strategy improvements to ensure emissions compliance and robustness through end-of-life requirements.
• Support definition of vehicle data acquisition requirements for fleet vehicles, including data logger architecture, communication interfaces, data collection strategies, and parameter selection for gasoline, hybrid, and future powertrain configurations.
• Establish standardized data acquisition specifications and measurement plans that provide visibility into performance, catalyst behavior, emissions control system operation, OBD monitor execution, and customer usage conditions.
• Develop and deploy fleet data analytics capabilities, including automated reporting, fleet health monitoring, trend analysis, anomaly detection, statistical analysis, and predictive analytics methodologies.
• Utilize vehicle and emissions datasets to identify emerging issues early in the development process and implement preventative actions prior to certification and Start of Production (SOP).
• Drive continuous improvement of connected fleet technologies,
