ConnectedCare Engineer

Omegro; Coleshill CP; On-site; GBP 65,000 - 90,000; Full time

Job summary

Trakm8 Group is seeking a ConnectedCare Engineer to own vehicle diagnostics capability behind ConnectedCare, our vehicle connectivity firmware. You will reverse engineer manufacturer-specific data and author decoding definitions and vehicle profiles for field use, covering new makes and variants with bench and in-vehicle testing.

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.
• Ability to own and rapidly learn an existing body of work, learning quickly with limited handover.
• Disciplined approach to testing, version control and documentation.
• Clear written and verbal communication, including with non-technical colleagues.

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.

Job description

Business UnitVBU - TrakM8Job DescriptionJob PurposeThe 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 & AuthoringCapture and analyse CAN bus and diagnostic data from vehicles to reverse engineer manufacturer-specific parameters, fault codes (DTCs) and diagnostic responsesAuthor, test and release the decoding definitions and vehicle profiles that ConnectedCare uses across the supported vehicle estateExtend vehicle coverage to new makes, models and variants in line with commercial prioritiesMaintain and improve vehicle fit data and connection profiles, including OBD-II, UDS and J1939 based diagnosticsOwnership & KnowledgeTake full ownership of the ConnectedCare decoding libraries, vehicle profiles and reverse engineering toolchainDocument vehicle coverage, decoding logic and reverse engineering findings so knowledge is shared, not siloedBuild and share vehicle diagnostics knowledge across the wider Devices teamQuality & TestingValidate the accuracy of decoded diagnostic data, fault codes and fit data on the bench and in vehicles before releaseDevelop and maintain test rigs, captures and automated checks for decoding definitionsContribute to the team's quality standards, review practices and release disciplineSupport & EscalationAct as the technical (L3) escalation point for vehicle connectivity and diagnostic data issues, performing root cause analysis across vehicle, device and decoding layersWork with Customer Success and Service Delivery to resolve field issues within agreed service levelsIdentify trends in connectivity faults, decoding errors and repeat issues, and feed fixes into the roadmapCollaboration & ImprovementWork with the Devices Team Lead on planning, estimation and prioritisation, including new vehicle coverage requestsWork with firmware engineers where coverage or fixes require firmware changes, and with platform and cloud teams on the end-to-end flow of vehicle dataMake effective use of AI-assisted analysis and development tools in line with team practicesSkills / Experience / Competency Required:Essential3+ years of experience in automotive diagnostics, vehicle telematics or a closely related engineering fieldHands-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 formatsWorking knowledge of vehicle diagnostic protocols: OBD-II as a minimum, ideally UDS (ISO 14229) or J1939Scripting skills (e.g. Python) for data capture, analysis and toolingMethodical, evidence-based approach to validating decoded data before releaseComfortable taking ownership of an existing body of work, learning it quickly and working with limited handoverDisciplined approach to testing, version control and documentationClear written and verbal communication, including with non-technical colleaguesDesirableAbility 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 similarCAN FD, DoIP or manufacturer-specific diagnostic experienceExperience building or using vehicle test benches, simulators or HIL rigsKnowledge of vehicle electrical architectures and EV-specific diagnosticsExperience providing L3 support or working closely with customer support teamsExperience with AI-assisted tools for large-scale data analysisPersonal Attributes:Naturally curious puzzle-solver who enjoys making sense of undocumented data and protocolsTakes genuine ownership and sees problems through to resolutionQuality-driven, understanding that customers make fleet and maintenance decisions on the data this capability producesPatient and persistent;
