Job description

Fleet Support Engineer – Vehicle Motion Control & Safety Controllers

Overview

Support the reliability and operational uptime of an advanced vehicle fleet by diagnosing and resolving complex issues involving safety-critical electronic control units (ECUs). As a Fleet Support Engineer, you will serve as a primary technical resource for real-time escalations affecting primary and backup motion-control units, fail-operational systems, controller communications, and safe-stop functionality.

This hands‑on role partners closely with engineering, operations, and field teams to perform root cause analysis, implement corrective actions, validate repairs, and develop troubleshooting resources that improve fleet performance. The ideal candidate brings deep embedded systems expertise, strong CAN‑bus debugging skills, and the ability to drive problems from high‑level vehicle behavior down to component‑level detail.

Required Skills and Qualifications

• At least 4 years of relevant experience in transportation, aerospace, autonomous vehicles, or a related field focused on embedded vehicle controllers, motion control, or safety‑critical ECUs
• Bachelor’s degree in Electrical Engineering, Electronics Engineering, Computer Engineering, Mechanical Engineering, or a related discipline
• Hands‑on experience with embedded ECUs and real‑time control systems, including microcontroller‑based architectures and state machines
• Strong understanding of fail‑safe and fail‑operational architectures, redundant control strategies, and safety‑critical systems
• Ability to interpret electrical schematics, harness diagrams, and state‑machine diagrams
• Experience debugging Unified Diagnostic Services (UDS) issues
• Extensive experience with CAN architecture and frame‑level troubleshooting using tools such as Vector CANalyzer, CANoe, or PCAN
• Experience diagnosing controller faults, unresponsive or unreachable controllers, failed resets, and stale or locked‑up controller messaging
• Knowledge of command and feedback paths between primary compute systems, motion‑control units, and downstream body, thermal, powertrain, and chassis controllers
• Ability to conduct root cause analysis and implement interim and permanent corrective actions
• Holistic problem‑solving approach, with the ability to connect vehicle‑level functions to component‑level issues
• Strong technical documentation, communication, and cross‑functional collaboration skills
• Proactive, self‑directed approach to troubleshooting in real‑time service and fleet operations environments
• Ability to pass a background check and Motor Vehicle Record (MVR) check

Nice‑to‑Have Skills

• 3 or more years of experience in firmware validation for embedded systems
• Experience with Hardware‑in‑the‑Loop (HIL) and Software‑in‑the‑Loop (SIL) validation methodologies
• Experience preparing test plans from firmware requirements or state machines
• Familiarity with automotive network gateways, including CAN‑to‑Ethernet and Diagnostics over Internet Protocol (DoIP) communication
• Strong understanding of embedded controls, state machines, controller takeover and arbitration logic, and physical sensor and actuator interfaces
• Experience providing remote support for vehicle troubleshooting
• Experience with Linux and Python‑based systems for fleet‑level data processing
• Experience validating component and vehicle bring‑up, functional verification, and controller firmware alignment following replacement or repair

Preferred Education and Experience

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, Computer Engineering, Mechanical Engineering, or a related field
• Four or more years of relevant experience with embedded vehicle controllers, motion control, safety‑critical ECUs, or real‑time control systems
• Experience supporting complex vehicle systems in transportation, aerospace, autonomous vehicle, or comparable safety‑critical environments

Other Requirements

• Onsite position in Foster City, California
• W2 employment only
• Six‑month contract assignment
• Availability for night and weekend shifts as needed, with advance notice
• Occasional travel to support operations at various locations
• Ability to support real‑time fleet escalations and collaborate effectively across engineering, operations, and field teams
