Sr. Materials Test Engineer, Cell Electrolyte

Battery Cells EngineerBattery cells are the common denominator for every Tesla product. Our product requirements demand ground-up cell architectures with state-of-the-art performance, manufactured at volumes that are orders of magnitude higher than the products they power. Our environment is fast-paced and incredibly exciting, so being passionate and self-motivated to push your limits is critical. Our team works with engineering groups across various disciplines, requiring strong communication skills and a team-first mentality. You will work alongside seasoned industry experts, high aptitude recent graduates, and people from every stage in between. We are looking for anyone with an exceptional ability to solve problems in both individual and team settings. Our team is heavily focused on cell materials design and qualification. Your responsibility will be developing and executing tests quantifying electrochemical and physical properties of advanced electrolytes, interpreting data, and accelerating qualification of new electrolyte systems.ResponsibilitiesDesign, develop, and execute tests to quantify electrochemical and physical properties of advanced electrolytes with high accuracy, including conductivity, impedance, electrochemical stability, viscosity, density, salt diffusivity, cation transport number, and phase behaviorBuild, run, and debug experiments directly in custom fixtures and non-standard cells and define test hardware needs with mechanical engineering collaboratorsInterpret characterization data and assign result differences to electrolyte behavior, test methods, fixtures, or assembly flawsReproduce and adapt test methods from materials development partners, and communicate key results, gaps, and risksMaintain test equipment and high standards of data quality, with records complete enough for others to repeat the methodPlan, prioritize, and communicate the status of lab testing to hit project deadlinesRequirementsDegree in Chemical Engineering, Chemistry, Materials Science, Mechanical Engineering, or equivalent experience5+ years of hands-on experience developing and executing electrochemical or physical-property test methodsExperience testing electrolytes, liquids, or other fluids in custom fixtures or non-standard setupsAbility to set up, execute, and debug experiments directlyKnowledge of safe laboratory practice with hazardous chemicalsExperience developing test methods for materials that require specialized handling or containment strongly desiredExcellent written and verbal communication skills, and the ability to work with electrolyte, mechanical, and analytical partnersFamiliarity with analytical methods such as GC, NMR, Karl FischerCompensation & 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 programEarned Wage Access: Real-time pay access paid daily, subject to eligibility and schedule (applicable for below Sr. Managers levels)Expected Compensation $87,020 - $185,820/annual salary + cash and stock awards + benefitsPay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
