Job summary

Custom Denning, Australia’s only local fully electric bus manufacturer, seeks a Software Engineer to design and maintain software for vehicle control systems in production buses. You'll work across embedded ECUs, CAN networks, diagnostics and OTA updates on site in Sydney.

You’ll bring a degree in software or related field and 3+ years of embedded/ automotive experience, with C/C++ and CAN tooling expertise. Join a practical, hands-on team on the production floor.

Qualifications

• Bachelor's degree in Software Engineering or related discipline.
• 3+ years' experience in software development, preferably embedded/autmotive/EV.
• Strong programming in C/C++; Python or C# for tooling/test automation is a plus.
• Experience with CAN bus networks and protocols (J1939, CANopen, UDS) and tools such as Vector CANalyzer/CANoe or PCAN.
• Familiarity with EV systems—battery management, inverters, drivetrain and charging (CCS/OCPP).
• Experience with Git, testing, and software development lifecycle; awareness of ISO 26262 or cybersecurity is advantageous.
• Hands-on approach, comfortable on vehicles and production floor, not just desk-based.
• Strong problem-solving and cross-functional collaboration.

Responsibilities

• Design, develop and maintain software for vehicle control systems, from requirements through to production release.
• Develop and integrate embedded software (C/C++) for ECUs, body control and driver interface systems.
• Configure, integrate and troubleshoot CAN/J1939 vehicle networks, including battery, drivetrain, charging and auxiliary systems.
• Build diagnostic, end-of-line test and calibration tools to support the production line.
• Support telematics, data logging and OTA updates across the fleet.
• Investigate and resolve software and integration issues on prototype and production vehicles using root‑cause analysis.
• Develop and execute test plans, including bench, HIL and on‑vehicle validation.
• Maintain software documentation, version control, release notes and ECNs.
• Collaborate with electrical, mechanical, production and quality teams and suppliers.
