You will collaborate with firmware, platform and cloud teams, delivering reliable data for fleet and maintenance decisions while maintaining comprehensive documentation

Qualifications

• 3+ years of experience in automotive diagnostics, vehicle telematics or a closely related engineering field.
• Hands-on experience capturing and analysing CAN bus data with common analysis tools (e.g. CANalyzer, PCAN, SavvyCAN).
• Proven experience reverse engineering undocumented or manufacturer-specific vehicle data, protocols or binary formats.
• Working knowledge of vehicle diagnostic protocols: OBD-II at minimum, ideally UDS (ISO 14229) or J1939.
• Scripting skills (Python) for data capture, analysis and tooling.
• Methodical, evidence-based approach to validating decoded data before release.

Responsibilities

• Diagnostics Reverse Engineering & Authoring: Capture and analyse CAN bus and diagnostic data to reverse engineer manufacturer-specific parameters, fault codes (DTCs) and diagnostic responses.
• Author, test and release decoding definitions and vehicle profiles that ConnectedCare uses across the supported vehicle estate.
• Extend vehicle coverage to new makes, models and variants in line with commercial priorities.
• Maintain and improve vehicle fit data and connection profiles, including OBD-II, UDS and J1939 based diagnostics.
• Document vehicle coverage, decoding logic and reverse engineering findings so knowledge is shared, not siloed.
• Act as the technical (L3) escalation point for vehicle connectivity and diagnostic data issues, performing root cause analysis across vehicle, device and decoding layers.
• Work with Customer Success and Service Delivery to resolve field issues within agreed service levels.
