ConnectedCare Engineer

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

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

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

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

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

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

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

Naturally curious puzzle-solver who enjoys making sense of undocumented data and protocols

Takes genuine ownership and sees problems through to resolution

Quality-driven, understanding that customers make fleet and maintenance decisions on the data this capability produces

Patient and persistent; comfortable with investigations that take time to crack

Self-sufficient and resourceful, but knows when to ask for help

Collaborative team player who documents and shares knowledge willingly

We’re a close-knit team who care about each other, our customers and making a positive impact, our values drive who we are and the decisions we make:

Caring & Committed – We show up for each other and deliver with dedication

Make a Difference – We create impact that matters

Relentless – We push forward until we succeed

Do the Right Thing – We choose integrity every time
