ECU Developer- ECU, ControlsWork Location: Waukesha, WI, USAStrong ECU development background – hands-on experience working with Electronic Control Units. 10+ years of experience.Coding proficiency – ability to contribute directly to implementation (not just requirements).Strong knowledge of microcontroller architectures (ARM, Infineon, NXP, Renesas) and embedded C/C++.Firmware experience – practical familiarity with embedded firmware and low-level development workflows.Engine systems expertise – deep understanding of engine behavior, calibration, and related requirements.Requirements engineering – must be comfortable interpreting, managing, and implementing technical requirements for engine/ECU systems.Perform board bring-up, debugging, and validation of hardware platforms.Develop low-level firmware and drivers for microcontrollers and SoCs.Conduct HIL/SIL testing and validation of ECU hardware and software.Familiarity with engineering tools like CANoe, CANApe.Knowledge of communication protocols (CAN, LIN, FlexRay, Ethernet) and diagnostic services (UDS, OBD) highly beneficial.Knowledge of ISO 26262 Functional Safety, AUTOSAR, and ASPICE standards beneficial.Knowledge of Python or MATLAB/Simulink for model-based development.Exposure to bootloaders, firmware updates.On-site in Waukesha is strongly preferred due to hardware dependencies and proximity to the design team.Remote work acceptable only short-term but may slow progress.
