Vehicle Diagnostic Engineer

What we're buildingEvery idea starts with a problem. Ours was simple: Boats are special — but they're loud, pollutant, unreliable, and stuck in the past. Gas-powered boats dominate not because they're great, but because no better option has existed. Until now.Arc is here to change that. We're building 100% electric boats from the ground up — quicker, quieter, easier to maintain, and better for the water they ride on. We're not just swapping gas for batteries. We're rethinking every detail on the boat — from propulsion and powertrain to software and ownership model — applying first-principles engineering from aerospace and EVs to deliver a better boating experience.Electric boats haven't taken over yet. The tech hasn't been ready. The talent hasn't been focused here. That's our opportunity — and we're moving fast.Who we're looking forWe're looking for someone who's fired up by our mission and ready to build. You'll thrive here if you adapt quickly, take ownership, and care about the details.This is a full-time, on-site role at our Los Angeles headquarters. You will work on vehicle level debugging, system analysis, and root cause investigation. You'll report to Director, Field Service. and work closely with a lean, high-trust team where everyone's work matters.Core responsibilitiesFault Isolation: Determining if an issue is a software logic bug, a communication protocol error, a configuration mismatch, or a physical hardware defect.End-to-End Debugging: Own the investigation of vehicle-level issues from the first symptom through to the root cause hypothesis.Driving structured root cause investigations using data, instrumentation, and experimentationContributing to validation strategies including bench testing, HIL, and production-level verificationImproving system reliability, diagnosability, and serviceability across product iterationsContributing meaningfully to code reviews, design reviews, and technical problem solving within the controls teamSignal Diagnostics: Performing deep-dive timing analysis, plausibility checks, and state transition reviews of ECUs, sensors, and actuators.Hands-on Testing: Reproduce complex issues on real vehicles, capturing logs (ECU, network, and system traces) to document findings.Collaborating with engineering and production teams to implement improvements on boat designs, production methods, or service processes.Basic Qualifications5+ years of experience in embedded systems, controls, or vehicle electrical integrationBS in Electrical, Computer, or Automotive Engineering or equivalent experience.Ability to work an on-call schedule that will include off-hours and weekendsStrong hands-on experience building and debugging real-time, hardware-integrated systemsDeep familiarity with CAN-based architectures and network-level debugging toolsDemonstrated experience shipping complex hardware-integrated systems into productionStrong intuition for system-level tradeoffs under real-world constraintsAbility to operate independently and drive execution without heavy oversightPhysical Proficiency: Comfortable working hands-on with vehicles in a shop or test environment.Travel up to 20% for field investigations and global engineering sprints.Bonus QualificationsExperience with EV or marine electrical architecturesProficiency in C/C++, Rust, Python, or similar languages for embedded or automation developmentExperience with Asana, Grafana, ion, slack and other web-based communication platformsExperience with model-based design or control algorithm developmentFamiliarity with DFMEA, functional safety, or reliability engineering practicesExperience building automated validation or HIL infrastructureComfort working directly with oscilloscopes, data loggers, and ECU flashing toolsComfortable pushing a fast but sustainable paceEnthusiasm for boating and clean energyAt Arc, we encourage diversity and consider all qualified applicants equally for employment, regardless of background, identity, or status. You're always welcome to reach out even if you don't meet many of these qualifications. Passion and aptitude make up for a lot.Our valuesWe move with urgency and build with care. We value these five things above all else:Ownership over both your work and the company's successEmpathy for colleagues and for customersHumility in problem solving and collaborationPragmatism for navigating ambiguity quickly and sensibly Inclusion of different backgrounds, opinions, cultures, and perspectives.We want people who share and embody these values. It is vital that our values align - we'd be happy to elaborate on any or all of these during the interview process.What we offerWe don't think great work happens by accident.
