Job Description
Job Purpose
The ConnectedCare Engineer owns the vehicle diagnostics capability behind ConnectedCare, Trakm8's vehicle connectivity firmware. This is primarily an aftermarket diagnostics reverse engineering and authoring role: capturing and analysing manufacturer-specific vehicle data, reverse engineering how each make, model and variant presents its diagnostic data, fault codes (DTCs) and fit data, and authoring the decoding definitions and vehicle profiles that ConnectedCare uses in the field. This role restores and secures that capability within the Devices team.
The role covers the full lifecycle: extending vehicle coverage to new makes, models and variants, authoring and validating decoding definitions and fit data, testing on the bench and in vehicles, documentation, and acting as the technical escalation point for vehicle connectivity and diagnostic data issues raised by Customer Success. It is not primarily a firmware development role; the engineer works alongside firmware colleagues where changes need firmware support. Customers make fleet, maintenance and fault management decisions based on the data this capability produces, so accuracy and reliability are central. The engineer is expected to build strong documented knowledge of vehicle coverage and decoding logic so that capability is never again dependent on a single person's undocumented knowledge.
Key Responsibilities
Diagnostics Reverse Engineering & Authoring
- Capture and analyse CAN bus and diagnostic data from vehicles to reverse engineer manufacturer-specific parameters, fault codes (DTCs) and diagnostic responses
- Author, test and release the 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
Ownership & Knowledge
- Take full ownership of the ConnectedCare decoding libraries, vehicle profiles and reverse engineering toolchain
- Document vehicle coverage, decoding logic and reverse engineering findings so knowledge is shared, not siloed
- Build and share vehicle diagnostics knowledge across the wider Devices team
Quality & Testing
- Validate the accuracy of decoded diagnostic data, fault codes and fit data on the bench and in vehicles before release
- Develop and maintain test rigs, captures and automated checks for decoding definitions
- Contribute to the team's quality standards, review practices and release discipline
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Support & Escalation
- 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
- Identify trends in connectivity faults, decoding errors and repeat issues, and feed fixes into the roadmap
Collaboration & Improvement
- Work with the Devices Team Lead on planning, estimation and prioritisation, including new vehicle coverage requests
- Work with firmware engineers where coverage or fixes require firmware changes, and with platform and cloud teams on the end-to-end flow of vehicle data
- Make effective use of AI-assisted analysis and development tools in line with team practices
Skills / Experience / Competency Required
Essential
- 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 as a minimum, ideally UDS (ISO 14229) or J1939
- Scripting skills (e.g. Python) for data capture, analysis and tooling
- Methodical, evidence-based approach to validating decoded data before release
- Comfortable taking ownership of an existing body of work, learning it quickly and working with limited handover
- Disciplined approach to testing, version control and documentation
- Clear written and verbal communication, including with non-technical colleagues
Desirable
- Ability to read and navigate C/C++ firmware code (this is not primarily a firmware development role)
- Experience in the vehicle aftermarket: diagnostics tools, telematics retrofit, ECU tuning or similar
- CAN FD, DoIP or manufacturer-specific diagnostic experience
- Experience building or using vehicle test benches, simulators or HIL rigs
- Knowledge of vehicle electrical architectures and EV-specific diagnostics
- Experience providing L3 support or working closely with customer support teams
- Experience with AI-assisted tools for large-scale data analysis
