Vehicle Diagnostic Engineer

About the role

As a Vehicle Diagnostic Engineer, you will serve as a primary technical front line for diagnosing and resolving complex issues across Arc’s production fleet. Your role involves leading technical triage, narrowing root causes, and driving fast, high-quality decisions to route issues efficiently and keep vehicles moving. You will contribute across debugging, investigation, validation feedback, and broader service enablement while helping build a more scalable support model as Arc grows.

Responsibilities

• Investigating vehicle-level issues from initial symptom through root cause identification and resolution
• Determining whether issues originate from software logic, communication protocols, configuration mismatches, or physical hardware defects
• Performing deep-dive diagnostics including timing analysis, plausibility checks, and state transition reviews across ECUs, sensors, and actuators
• Reproducing complex issues on real vehicles and capturing ECU, network, and system-level logs to document findings
• Driving structured root cause investigations using data, instrumentation, and experimentation
• Driving fast, high-quality technical decision making in ambiguous and time-sensitive situations
• Triage complex issues and coordinating resolution across service and engineering teams
• Contributing to validation strategies including bench testing, HIL, and production-level verification
• Collaborating with engineering and production teams to implement improvements to boat designs, production methods, and service processes
• Improving system reliability, diagnosability, and serviceability across product iterations
• Contributing to technical problem solving, design reviews, and cross-functional debugging efforts with engineering teams

Requirements

• 2+ years of experience in vehicle diagnostics, service engineering, vehicle electrical integration, embedded systems, controls, or technical escalation engineering
• AS degree or higher in Electrical Engineering, Computer Engineering, Automotive Engineering, or equivalent practical experience
• Strong hands-on experience debugging and integrating real-time, hardware-integrated systems
• Deep familiarity with CAN-based architectures, vehicle communication networks, and diagnostic tools
• Experience troubleshooting and supporting complex hardware-integrated products in production environments
• Systems thinking and sound technical judgment under real-world constraints and ambiguous conditions
• Comfortable working hands-on with vehicles in shop, prototype, production, or test environments
• Ability to operate independently and drive execution with minimal oversight
• Ability to travel up to 15% for field investigations and engineering sprints

Bonus Qualifications

• Experience with EV, marine, or other electrified vehicle architectures
• Experience with telemetry, observability, or diagnostic platforms such as Grafana, ION, or similar tools
• Experience using oscilloscopes, data loggers, CAN tools, and ECU flashing tools
• Experience supporting production systems and driving issue resolution across cross-functional teams
• Experience building automated validation, test, HIL, or diagnostic infrastructure
• Experience with model-based design, controls systems, or control algorithm development
• Proficiency in Python, C/C++, or similar languages for diagnostics, embedded systems, automation, or tooling development
• Familiarity with vehicle communication protocols, data analysis, or signal visualization tools
• Familiarity with DFMEA, functional safety, or reliability engineering practices
• Comfortable operating at a fast but sustainable pace
• Enthusiasm for boating and clean energy
