Senior QA Engineer - Vehicle Networks and Telematics

Role Overview

As a Senior QA Engineer in the CAN QA team, you will own validation of how our devices read, interpret and report vehicle data, from the CAN bus through the device to the cloud. You will develop test strategies for J1939 and OBD-II integrations, automate protocol and signal-level testing, investigate complex field issues, and provide evidence-based release-readiness recommendations.

This is a hands-on role for someone equally at home with a CAN trace, a bench power supply and a truck cab, and who can convert requirements, DBCs, logs and field evidence into reliable qualification coverage.

What You Will Own

• Validation strategy and release qualification for CAN-based vehicle features, new vehicle onboarding and customer configurations.
• Requirement-to-test coverage for vehicle signals, diagnostics, power modes and end-to-end telematics workflows.
• Root-cause investigation of signal mismatches, intermittent CAN failures and vehicle-specific field issues.
• Reusable CAN simulation, trace replay, fault-injection and automated regression capabilities.
• Technical guidance through test-design reviews, automation reviews and structured defect triage.

Key Responsibilities

Vehicle Networks and Diagnostics

• Validate SAE J1939 PGN/SPN decoding for vehicle speed, odometer, engine hours, fuel, DM1/DM2 faults and other supported signals.
• Validate OBD-II modes, PIDs, DTCs and VIN handling using SAE J1979 and ISO 15765-4.
• Verify scaling, offsets, units, ranges, rollover, timeouts, stale data, source-address handling and not-available values.
• Test J1939 transport protocol (BAM and RTS/CTS), request messages, address claim and bus-off recovery.
• Correlate device-decoded values with trusted CAN tools and OEM or dealer diagnostic systems.

Power Modes and CAN Wake-up

• Validate wake-up on CAN traffic and ignition, sleep after bus silence, shutdown and recovery across supported configurations.
• Measure quiescent current and verify that the device causes no unwanted wake-ups, excessive bus traffic or vehicle battery drain.
• Validate ignition (KL15) and battery (KL30) scenarios, brownouts, power interruptions and repeated ignition cycles.

Bench, HIL and Vehicle Testing

• Set up and execute bench, HIL and in-vehicle tests using CAN interfaces, programmable power supplies, ignition control and harnesses.
• Simulate ECUs, replay recorded traces, inject protocol and signal faults, and reproduce field scenarios in the lab.
• Validate integrations across commercial and passenger vehicles, makes, models and model years, including in fleet yards and at customer sites.

End-to-End Feature Validation

• Validate CAN-derived data from vehicle bus to cloud for fleet features such as fuel consumption, fuel-level trends, idle fuel, refueling and suspected fuel theft.
• Validate CAN-derived inputs supporting ELD/HOS workflows, including engine power state, vehic
