Job description

• Contribute to and help optimize Ford's technology roadmap by providing hands-on lab testing insights, data, and technical feedback that inform product development timelines and priorities.
• Author, review, and validate step-by-step Standard Operating Procedures (SOPs), safety guides, and Technical Service Bulletins (TSBs) for field technicians.
• Document and compile test logs, teardown results, and failure investigation data into clear, concise technical reports for design and quality engineering teams.
• Support the development of standardized cost structures for authorized third-party service providers by delivering accurate lab testing data, benchmarks, and technical assessments.
• Perform high-level diagnostics and fault isolation on field-returned BESS components, including battery management systems (BMS), high-voltage junction boxes, power distribution units, and thermal management (HVAC/liquid cooling) systems.
• Utilize advanced diagnostic software, CAN bus analysis tools (e.g., Vector CANalyzer), oscilloscopes, and thermal imaging cameras to identify hardware, software, and communication failures.
• Set up and operate battery test equipment, battery pack cyclers, hardware-in-the-loop test rigs, and data acquisition systems.
• Execute complex electrical, thermal, and mechanical test plans to validate proposed service parts, firmware/software updates, and field repair procedures.
• Fabricate and assemble custom test fixtures, wire harnesses, and prototype components to support special engineering investigations.

Requirements

• Education: Associate degree in Electrical Engineering Technology, Electronics, Mechanical Technology, or equivalent military training/trade school certification or work experience.
• Experience: 5+ years of hands-on experience in a development lab, quality lab, or manufacturing repair environment working directly with high-voltage (HV) electrical systems or battery systems (BESS, EV battery packs, power electronics).
• Technical Skills: Strong working knowledge of DC electricity (up to 1500V or higher) and three-phase AC power systems.
• High proficiency reading and interpreting complex electrical schematics, single-line diagrams, piping and instrumentation diagrams, and technical drawings.
• Experience with automotive/industrial network communication protocols (CAN, Modbus, TCP/IP, Ethernet).
• Hands-on proficiency with diagnostic equipment: digital multimeters (DMMs), insulation resistance testers (Megger), high-voltage probes, and thermal cameras.
• Certifications: Active or prior certification in high-voltage safety (e.g., NFPA 70E, OSHA 10 or 30).

Core Competencies

Demonstrates expertise in high-voltage electrical systems and battery management systems, with a strong ability to perform diagnostics, develop technical documentation, and execute complex test plans.
