Sr. Software Engineer, AC Charging

Software EngineerWe're building the charger that shows up on millions of walls and powers tens of millions of cars. Wall Connector is also a cornerstone of Tesla's bidirectional vehicle strategy, unlocking energy at terawatt-hour scale for our customers. The Tesla Energy Device Software team is looking for a Software Engineer to build firmware and device software for Wall Connector and Tesla's broader AC charging product line: install cleanly, charge safely, meter accurately, talk reliably to vehicles and the Tesla ecosystem, stay compliant across global markets, and ship continuous improvements over the air.Depending on team needs and your background, you may own work across embedded charging features such as metering, communications, safety interlocks and fault handling, and real-time control behavior; device platform & site controls such as embedded Linux services, local coordination (including multi-unit / site-oriented controls such as load and energy sharing concepts around V2X), and integration with third-party systems and partners; and global product readiness such as regional compliance, and certifiable software paths for new marketsThese products resemble other IoT systems in many ways: they need to be installed, configured, diagnosed, and kept healthy in the field. Once operational, they run autonomously, respond to commands, and provide useful telemetry with the added bar of EV safety, metrology, and regulatory constraints. Our stack is diverse: bare-metal / RTOS firmware, embedded Linux, local and cloud-facing protocols, and validation tooling. Pragmatism, willingness to dive into new codebases and standards, eagerness to work with stakeholders (hardware, validation, compliance, product, partners), and engineering leadership are key strengths we expect you to bring to the table.ResponsibilitiesDesign, implement, and debug AC charging device software in C & Rust across real-time embedded and embedded Linux environmentsOwn or contribute to core product areas such as metering, comms stacks, safety-related behaviors, charging state machines, diagnostics, and OTA-safe feature deliveryCollaborate with Product, Hardware, Validation, and Compliance to turn requirements (including regional compliance) into clear designs, tests, and shippable firmwareBuild and maintain software for installation, configuration, commissioning, and field diagnosis; improve reliability and debuggability of devices already in the fleetContribute to site-oriented controls and third-party integration where needed (e.g. multi-charger coordination, energy/load sharing concepts, partner or external system interfaces adjacent to Wall Connector)Work with other engineering teams on APIs and boundaries between control firmware, platform services, mobile/cloud, and partner systemsContribute to system architecture, automated tests, and engineering practices that raise product reliability, developer productivity, and release confidenceSupport production and fleet needs: bring-up issues, field anomalies, and continuous improvement after launchRequirementsDegree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent experienceAbility to multi-task, prioritize, and work in an extremely fast-paced, collaborative environmentExperience developing mission-critical embedded or device software and corresponding test suitesProficiency in systems languages used on-device (e.g. C, Rust, Go a plus) and comfort debugging real hardwareReal-world experience in one or more of: Real-time / RTOS or bare-metal firmware (peripherals, drivers, safety-minded state machines); Embedded Linux application or middleware development; Device comms (UART, CAN, Ethernet, Wi?Fi, BLE, or similar); Metering, power/energy measurement, or regulatory-constrained measurement softwareStrong software fundamentals: clear interfaces, maintainability, failure handling, and testabilityExperience with unit / integration / HIL-style validation, reading schematics, or lab bring-up is a plusExposure to EV charging, safety standards, global/market compliance, multi-device site controls, or third-party protocol integration is a plusCompensation & 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$120,000 - $396,000/annual salary + cash and stock awards + benefitsPay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
