ABOUT TRU HYBRID & EV BATTERIES TRU
Hybrid & EV Batteries is a specialized battery remanufacturing and installation shop serving consumers, independent repair shops, and dealerships. We offer both remanufactured batteries with the industry's best 3-year warranty and brand-new batteries with a lifetime warranty. We ship nationwide and serve walk-in customers at our Tukwila, WA facility. What sets us apart:
every battery we deliver comes with a detailed Transparent Performance Report — per-unit test documentation that shows the customer exactly how their pack performs. We believe the customer deserves to see exactly what they're getting. That report is the foundation of our brand, and it's only as good as the person running the bench. That's the role we're hiring for. THE ROLE
You own the engineering and quality behind every battery TRU produces. The testing systems, procedures, and documentation already exist — they were built in-house and they work. We are not hiring someone to simply run them. We're hiring someone to take them further than we can today: to drive our quality from best-in-class to a level above the industry, own the hard battery-engineering and failure-analysis questions, and raise the bar on what a remanufactured pack can be. This is the central thing we're looking for: a proven track record of taking on hard, big problems and driving them to a result. Not maintaining a process — improving the things that are genuinely difficult, and the ones that are tedious and easy to avoid. The best person in this seat runs toward the problem nobody else wants to touch, gets to the root cause, and closes it. If your instinct when something is "hard or boring" is to work around it, this is not your role. Ideally, you know this domain more deeply than we do and can pull the whole operation up a level. You won't be expected to have every answer alone — we will bring in specialized outside expertise for the deepest engineering and chemistry questions — but you are expected to own the outcome: define the problem, know when to pull in help, manage it, and deliver the improvement. We want both the engineering foundation to understand these systems and the hands-on track record to actually change them. WHAT YOU'LL DO DAY-TO-DAY
Testing & Documentation Run the bench: Perform HV battery cell and pack performance testing using our equipment and software — charge/discharge cycling, capacity and internal-resistance measurement, and health verification. Own the Performance Report:
Produce the per-unit test documentation behind every Transparent Performance Report. Accurate, complete, on-protocol — because the customer sees it. Maintain records:
Keep detailed, organized documentation of test procedures, results, and observations in line with established protocols, and compile clean test reports. Quality control:
Be the final check on every finished pack. If it doesn't meet spec, it doesn't ship. Teardown & Remanufacturing Tear down and rebuild: Conduct HV battery teardown, sort and grade cells/modules, and rebuild packs to spec for remanufactured product. Manage inventory:
Track final-product inventory for remanufactured and new batteries, plus component and supply inventory tied to the bench. Quality & Engineering Ownership Push quality past the standard: Own our quality system and drive it beyond industry norms — first-pass yield, consistency pack-to-pack, and long-term reliability in the field. Run root-cause and failure analysis:
When a pack underperforms or comes back, you lead the investigation, find the true cause, and put a corrective action in place so it doesn't recur. Answer the hard engineering questions:
Cell matching and grading, degradation behavior, thermal and BMS issues, edge-case diagnostics — you take the open questions and close them, bringing in outside specialists when a problem runs deeper than our in-house knowledge. Tackle the unglamorous work:
The hardest and least interesting problems are often the ones holding quality back. You own those too — we don't cherry-pick only the fun projects here. Engineering, Automation & Systems Build and improve the rigs: Build, maintain, and improve our testing automation and tooling. When a process is slow, manual, or inconsistent, your instinct should be to engineer a better one. Systematize what works:
Lead testing process reviews, development, systematization, documentation, and risk assessments — turning what we do into repeatable, written procedures. Think like location #2 is coming: Every process and automation you build should be clear enough that an engineer at a second TRU location could follow it without calling you. That's the standard. Keep it safe and clean:
Maintain a safe, organized, professional workspace — essential when working with high-voltage systems. WHO YOU ARE
You have a track record of hard, big things. You can point to problems you owned end to end — difficult, ambiguous, or high-stakes — and the results you delivered. That history matters to us more than any single credential. You run toward the hard problems. The difficult and the tedious don't get skipped or worked around — they're exactly the work you take on, because that's where quality is won or lost. You're a self-starter. You don't wait to be told what to improve. You see a gap, you own it, and you drive it to done without being managed through every step. You go deep. You want to understand the engineering and the chemistry, not just follow the procedure — and you keep learning until you genuinely understand the system. You raise the bar. "Meets the standard" doesn't satisfy you. You're trying to make this the best in the industry, and you measure whether you got there. You know the edge of your knowledge — and you have no ego about it. When a problem is bigger than you, you bring in the right expertise, manage it, and still own the outcome. You're meticulous and safety-minded. A result is only useful if it's accurate and documented, and high voltage gets your respect every time — not just when someone's watching. EXPERIENCE THAT TRANSLATES WELL
On top of the engineering foundation, we want a real work history of building, testing, and troubleshooting physical systems — and of driving hard technical projects to a result. Automotive experience isn't required. These backgrounds tend to produce excellent candidates: Battery engineering, testing, pack building, or EV/HV systems work Battery or electrical failure analysis, root-cause investigation, or reliability engineering Quality or process engineering where you measurably raised yield, reduced defects, or cut returns Robotics design, build, or assembly (competition, hobby, or professional) Electronics or electrical bench work — prototyping, soldering, wiring harnesses, troubleshooting Automotive electrical, hybrid/EV service, or diagnostic technician roles Test automation, instrumentation, or controls (PLCs, sensors, data acquisition) R D, prototyping, or any role where you owned a hard, open-ended technical problem Military, trade, or manufacturing backgrounds with hands-on electrical work and a record of driving improvements REQUIREMENTS A
demonstrated track record of owning hard, ambiguous technical problems and driving them to a result — not just maintaining an existing process Bachelor's degree in Electrical Engineering or a related technical field A genuine work history of hands-on technical work — building, testing, and troubleshooting physical systems Solid electrical fundamentals and the ability to read and follow technical documentation Working knowledge of basic hand tools Strong attention to detail and disciplined documentation habits Strong problem-solving skills and a continuous-improvement mindset Ability to lift 80 lbs unassisted, several times throughout the day Strong working knowledge of English, especially for safety requirements and technical documentation Reliable transportation and a reliable commute to Tukwila, WA Authorization to work in the United States NICE TO HAVE

You'll have the autonomy to fix what's broken and the backing — including outside specialists — to solve the hardest problems Growth opportunity: As TRU expands, this role can grow into a Lead Engineer, Quality/Engineering Lead, or multi-location technical role. The standard you set here becomes the standard every future location follows. A team that values it:
We value transparency, quality, and doing right by the customer — not cutting corners. You'll build something you can stand behind. WHY TRU? Most shops sell parts and labor. We sell trust. Every battery we deliver comes with a Performance Report the customer can see and verify. Our 3-year warranty on remanufactured batteries is the best in the industry, and our lifetime warranty on new batteries speaks for itself. You won't be testing something you have to make excuses for. You'll be producing the proof behind a product you can stand behind. That's a better way to do this work. HOW TO APPLY
