We are looking for a curious, technically driven Vehicle Software Engineer to join a specialist automotive engineering team working across ECU reverse engineering, calibration research, embedded tooling and tuning development.
This is an exciting opportunity for a hands-on engineer who enjoys complex technical challenges, working at a low level with vehicle software, and turning analysis into practical solutions.
Key Responsibilities
- Reverse engineer automotive binary files and analyse firmware using IDA Pro and/or Ghidra.
- Investigate ECM/TCM/PCM behaviour, calibration tables, tuning parameters and map-switching logic.
- Work with TriCore, PowerPC and multicore automotive architectures.
- Develop tools, scripts and automation using C/C++, C# and Python.
- Work with CAN, UDS, CCP/XCP and KWP2000.
- Use automotive programming, flashing, diagnostics, data logging and calibration tools.
- Research and develop software/hardware access methods for modern vehicle control modules.
- Contribute to engineering projects, document technical findings and support junior engineers where required.
