Cell Test Engineer, Cell Qualification

Cell Test EngineerTesla is seeking a Cell Test Engineer for the Cell Engineering team to be part of a world-class team responsible for evaluating prismatic cell performance during early development across vehicle and energy storage programs. As a Cell Test Engineer, you own test methods, data quality, and execution so Cell Engineering can evaluate design options quickly and with high confidence. This includes turning test intent into robust plans, fixtures, and workflows; executing electrical, mechanical, and thermal testing; analyzing results; and closing the loop with design teams.

Cell Test Engineers use test data to validate design changes, improve lab capability, and protect execution quality in a fast-paced development environment.ResponsibilitiesDesign and execute electrical, mechanical, and thermal characterization and performance tests to quantify cell behavior, safety margins, and design tradeoffsTranslate engineering requirements into test plans covering sample size, conditions, instrumentation, pass/fail criteria, and data deliverablesOwn test execution quality, including scheduling, logistics, fixturing, setup, and data integrity from start of test through report-outAnalyze test data, identify trends and anomalies, and provide clear recommendations to Cell EngineersImprove test capability and throughput through method development, fixture design, equipment selection, automation, and process changesPartner with technicians and engineers to keep execution on SLA without sacrificing data qualityLead troubleshooting of test equipment, fixtures, and anomalous results, and drive root-cause and corrective actionSupport process and equipment validation, calibration strategy, and lab readinessUphold Tesla safety standards and escalate risks, equipment issues, or data-quality concerns promptlyRequirementsDegree in Electrical, Mechanical, Chemical, Materials Science, related engineering field, or equivalent in experienceExperience in a test, validation, or product engineering role, preferably batteries, electronics, or similar hardwareWorking knowledge of cell electrical fundamentals (voltage, current, capacity, impedance) and hands-on use of cyclers, DAQ, multimeters, and environmental chambersAbility to write structured test plans and turn raw data into conclusions using Excel and/or Python, MATLAB, or similarHands-on fixture, instrumentation, or equipment troubleshooting experienceHigh awareness of electrical, chemical, and thermal safety hazards and lab best practicesDirect experience with lithium-ion cell testing is highly desiredExperience with Neware, Arbin, BioLogic, or similar cyclers is a plusFixture design (CAD), scripting/automation, or DOE / statistical analysis is a plusStrong written and verbal communication, ownership as a self-starter, and proven collaboration with cross-functional engineering teamsCompensation & BenefitsBenefitsAlong with competitive pay, as a full-time Tesla employee, you are eligible for the following benefits at day 1 of hire:Medical plans > plan options with $0 payroll deductionFamily-building, fertility, adoption and surrogacy benefitsDental (including orthodontic coverage) and vision plans, both have options with a $0 paycheck contributionCompany Paid (Health Savings Accounts) HSA Contribution when enrolled in the High-Deductible medical plan with HSAHealthcare and Dependent Care Flexible Spending Accounts (FSA)401(k) with employer match, Employee Stock Purchase Plans, and other financial benefitsCompany paid Basic Life, AD&DShort-term and long-term disability insurance (90 day waiting period)Employee Assistance ProgramSick and Vacation time (Flex time for salary positions, Accrued hours for Hourly positions), and Paid HolidaysBack-up childcare and parenting support resourcesVoluntary benefits to include: critical illness, hospital indemnity, accident insurance, theft & legal services, and pet insuranceWeight Loss and Tobacco Cessation ProgramsTesla Babies programCommuter benefitsEmployee discounts and perks programExpected Compensation $87,020 - $156,180/annual salary + cash and stock awards + benefitsPay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
