Job Description

As a Calibration Engineer – Electric Powertrain Systems, you will be responsible for the functional calibration and optimisation of HV powertrain and charging systems across HEV, PHEV, and BEV architectures.

The role focuses on calibration strategy definition, software release support, and functional tuning using HIL, system test benches, and vehicles. You will work closely with software, system, and test & validation teams to ensure robust, efficient, and compliant electric powertrain performance.

Activities include:

· Define and maintain baseline calibrations for each electric powertrain software release

· Perform functional calibration of HV powertrain and charging systems, including:

o Energy management

o Thermal management

o Charging control (AC/DC)

o Torque management

o High voltage safety and diagnostics

· Execute calibration activities on:

o HIL platforms

o System and powertrain test benches

o Vehicles (road and laboratory environments)

· Use industry‑standard calibration tools such as INCA and CANape

· Review and assess Simulink models developed in‑house by the software team

· Ensure calibration parameters and strategies are:

o Correctly implemented in software

o Aligned with system requirements and functional intent

· Support software integration, testing, and release activities

· Provide feedback to software teams to improve model structure, tunability, and calibration robustness

· Create and execute calibration test cases derived from system and functional requirements

· Analyse measurements, logs, and KPIs to assess:

o Functional performance

o Efficiency and drivability

o Thermal and safety behaviour

· Document results and produce clear calibration and validation reports

· Support issue investigation, root cause analysis, and resolution

The Company is open to considering alternative engagement arrangements, including a self-employed basis, subject to mutual agreement.
