Emissions System Pre-Development Calibration Engineer

The Emissions System Pre-Development Calibration Engineer in the Medium and High Emissions and Aftertreatment (MHED) Group will be responsible for developing and integrating system technologies including engine hardware, exhaust sensors, control strategies, calibration, and the integration of these technologies into the propulsion system to meet upcoming emissions standards (e.g., TIER4, California LEV IV, EURO7, China 6, etc.) for future vehicle propulsion applications for gasoline internal combustion (ICE) and hybrid vehicles. Projects will utilize engine, powertrain, vehicle chassis dynamometers and/or simulation/modeling to make physics-based decisions and demonstrate proof-of-concept solutions to prove Propulsion functional objectives are satisfied. The engineer act as both an individual contributor and as part of teams within and outside of the MHED group. MHED interacts with core engine, controls, regulatory teams as part of a globally integrated Emissions and Aftertreatment group as part of the larger Propulsion Calibration (PCAL) Group.
