• Present development status updates to senior management.
• Oversee hardware development of emissions-critical components, including combustion systems, fuel injection, air handling (turbochargers, EGR), and aftertreatment systems (NOx, PM/PN).
• Develop and release calibrations for engine performance, emissions, aftertreatment control (deNOx, DPF), and diagnostics.
• Apply relevant emissions legislation to hardware and calibration strategies.
• Manage work packages within the JCB NPIP process.
• Coordinate test bed and machine calibration activities, including climatic testing, to meet emissions and performance targets.
This will be suited to you if
• You have a strong background in internal combustion engine calibration and emissions systems.
