Sr. Service Lab Technician BESS, Ford Energy
The Senior Service Lab Technician, Battery Energy Storage Systems (BESS) plays a critical role in diagnosing, testing, and developing service procedures for Ford Energy’s Battery Storage System. Operating in a primarily workshop environment, this role serves as the bridge between engineering, quality assurance, and field service operations, with occasional travel to the field to verify service procedures.
You will be simulating environmental/fault conditions, performing complex electrical diagnostics, and validating repair methodologies. As a senior member of the lab team, you will act as a champion for high-voltage safety compliance, mentor junior technicians, and actively contribute to root-cause analysis (RCA) to improve product reliability.
Key Responsibilities
Key Responsibilities
1. Documentation & Technical Writing
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.
Diagnostics, Troubleshooting & Root Cause Analysis
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.
3. Testing & Validation Operations
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.
4. Environmental, Health and Safety & Lab Stewardship
Enforce and adhere to the highest standards of lab safety, including NFPA 70E, OSHA regulations, and corporate high-voltage (HV) safety policies.
Act as an authorized person for Lock Out / Tag Out (LOTO) procedures on live HV DC and AC systems.
Maintain, calibrate, and organize laboratory equipment, hand tools, specialized diagnostics, and high-voltage Personal Protective Equipment (PPE).
Assess and implement ergonomic best practices in field settings, adapting tools, equipment, and work postures to reduce physical strain and injury risk across variable, non-lab environments.
5. Team Leadership & Collaboration
Train and mentor field technicians on safety protocols, testing techniques, and equipment operations.
Collaborate closely with BESS Design, Software, Quality, and Field Engineering teams to provide actionable feedback on product serviceability and reliability.
Position Qualifications and Key Capabilities
Required
Education: Associate degree in Electrical Engineering Technology, Electronics, Mechanical Technology, or equivalent military training/trade school certification.
