Software Engineer, Onboard Diagnostics

Description:
We are seeking a Software Engineer to build and own the diagnostic software that runs on our vehicles. You will develop the in-house frameworks at the core of vehicle diagnostics, including our Diagnostic Event Manager (DEM), the per-ECU process responsible for monitoring fault conditions and triggering Diagnostic Trouble Codes (DTCs). You will also support homologation teams in meeting evolving diagnostic and regulatory requirements worldwide. This role spans embedded firmware, diagnostic protocols, and compliance, and requires close collaboration across hardware, software, and service teams.

Responsibilities:
Develop and extend the Diagnostic Event Manager and DTC stack across vehicle controllers, defining how faults are detected, debounced, persisted to non-volatile memory, and reported over standard protocols such as UDS, CAN, and DoIP
Integrate the diagnostic framework across a range of controllers, embedded targets, and vehicle platforms, and manage versioned updates to these shared components in lockstep

Work with homologation teams to translate evolving diagnostic and regulatory requirements into actionable engineering work, and support certification and reporting activities

Build test infrastructure (e.g., SIL/HIL) that validates DEM and DTC behavior consistently across controllers and platforms

Develop diagnostic tooling and service routines that help technicians accurately identify and clear faults in the field

Monitor fleet-wide diagnostic data to track DTC trigger rates, and build dashboards that surface trends, catch regressions, and feed top field issues back to development teams

Collaborate with cross-functional teams to refine internal processes, streamline development, and drive on-time product releases

Document technical procedures and create guidelines that enhance collaboration and knowledge transfer

Requirements:
Degree in Computer Science, Electrical Engineering, Automotive Engineering, or related field, or equivalent experience

Proficiency in C/C++ or similar languages for embedded firmware development

Experience with automotive communication networks and diagnostic protocols (CAN, LIN, UDS, DoIP) for system development, validation, and troubleshooting

Experience developing across heterogeneous embedded targets and multiple vehicle platforms

Familiarity with diagnostic standards and concepts (e.g., DTCs, SAE J1979, ISO 13400)

Strong organizational skills to manage multiple timelines, prepare accurate documentation, and address audits

Excellent communication skills for coordination with cross-functional teams and, where needed, regulatory and industry bodies

Proven background in automotive diagnostics, including hands-on development of embedded diagnostic software, is a plus

Familiarity with global OBD regulations and certification processes is a plus
