Sr. Diagnostic Engineer - Charging Systems

Rivianis on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.

As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

As a key member of the Diagnostic Engineering team within Service Operations, you will develop and provide subject matter expertise in Vehicle High Voltage Charging Systems, Interoperability, and Industry Standards
. This is an individual contributor role responsible for coordinating and prioritizing software development for diagnostics
, evaluating and designing electrical architecture
, developing requirements for complex diagnostic systems
, utilizing AI tools to assist in diagnostics
, and monitoring and evaluating vehicle telemetry
.

• Working knowledge of vehicle charging standards - SAE J1772, SAE J3400 (North America), IEC 62196 (Europe), ISO 15118.
• Translate complex software code and requirements into clear technician diagnostic information and vehicle repair procedures.
• Represent Service as the primary liaison to the software domain, developing a working understanding of the codebase deep enough to partner effectively with Software Development; ensure software teams deliver the tools, processes, features, and bug fixes Service needs.
• Set field strategy based on DTCs to increase diagnostic accuracy and reduce repair time.
• Design software requirements for new DTCs to close gaps in issue detection.
• Use AI coding tools to build and modify skills files or generate small applications that support diagnosis of complex vehicle issues.
• Develop and continuously improve diagnostic content, testing procedures, evaluation logic, and automated scripts within Rivian's onboard and offboard diagnostic ecosystem.

• Partner with Software Development, Requirements Engineering, and Quality/Failure Analysis to design, develop, and refine onboard diagnostic software solutions that root-cause individual vehicle issues.
• Convert data trends from vehicle repairs into closed-loop feedback for hardware, software, and manufacturing design teams to drive continuous improvement.
• Consult with design engineers to resolve vehicle issues field teams and first-level escalation support cannot solve with available diagnostic resources, and feed learnings back into future diagnostics.

• Design test plans for diagnostic procedures, service calibration, and IT applications covering both expected success paths and failure/fault conditions, in coordination with software, hardware, and field technicians.
• Flash test assets to execute validation on target vehicles.
• Debug issues uncovered during test execution and drive them to root cause.
• Capture and analyze logs to verify diagnostic behavior and identify gaps in coverage.

• Produce and maintain technical documentation that maximizes diagnostic and service efficiency for the Service team.
• Monitor hardware performance across the fleet, initiating individual vehicle repairs, adjusting maintenance schedules, and defining software improvements to enhance product performance.

• BSc or MSc in a relevant engineering discipline;
  Electrical, Electronic, or Mechanical.
• 3+ years of experience with High Voltage Charging and EVSE in the automotive or comparable industry, combining theoretical and practical engineering experience.
• Experience with…
