What to Expect The Cell Equipment Design team is responsible for delivering high-capacity manufacturing systems to production. Our firmware processes millions of cells and determines their performance in our products. Tesla seeks an embedded software engineer to join the team in developing firmware, controlling in a reliable and safe manner for a variety of cell development projects including all Formation manufacturing processes, Cell Qualification phases, and special applications. The engineer is expected to perform software development through all product build phases, be a key partner between manufacturing and electrical design engineering, beginning with PCBA component and system design validation, factory acceptance testing, and production sustaining. We're looking for a motivated engineer to join our team and take responsibility for one of the many products we're currently designing (some announced, some not). The role will write software ranging from embedded C real-time controls to Python test software - whatever is necessary to get the job done. You will show outstanding organizational and communication skills and an eagerness to push the industry forward. What You'll Do Work on firmware projects within a sub-system such as cell cycling, microcontroller real-time operating systems, NVRAM interfaces, network programming, battery management algorithms, functional safety, cell dynamics, DCAC/DCDC power conversion control, electrochemical impedance spectroscopy (EIS), thermal management, and HVAC controls Develop highly reliable C, Python code that is structured, documented, maintainable, and reusable. Integrate software into production systems and perform regression testing Evaluate new manufacturing processes for controllability and fit to system needs Collaborate with other firmware developers and integration engineers to implement, test, debug, and calibrate your features in our production lines and research labs Contribute to and participate in software testing and continuous deployment processes Outline controller requirements based on system performance specifications. Participate in cross functional efforts to define microcontroller capability and establish actuation/sensing requirements Own firmware through life cycle from prototype to high-volume production, author high-quality C code in a real-time embedded environment Solve hard, undefined problems with limited direction. Hands-on with hardware bring-up and prototyping What You'll Bring Degree in Electrical Engineering, Computer Engineering, or related field, or equivalent experience and proof of exceptional skills with practical experience developing, implementing, and testing power electronics controls and/or battery electronics Proficient in languages such as C, C++, Golang, Python, and/or Rust. Experience developing real-time safety-critical firmware (C/C++) Experience validating complex systems (Note: this is not a validation role but understanding this part of the process is important to the success of the job) Familiarity with protocols such as CAN, UDS, Protocol Buffers, gRPC, MQTT, TCP/IP, OPCUA Understanding of embedded technologies (ADC, PWM, SPI, UART, I2C, CMPSS, DAC, etc.) Exceptional understanding of electrical engineering concepts, strong hands-on testing and troubleshooting skills Robust understanding of software fundamentals including software design, Git, scripting, CI/CD, algorithms, basic data structures, code modularity, and maintainability Demonstrate a good understanding of testing concepts including white box and black box testing, regression testing, unit testing, and performance testing Strong interest to collaborate cross-functionally, willingness to work hands-on, and dive into open-ended projects in a fast-paced environment Excellent communication skills and attention to detail Compensation and Benefits Benefits Along 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 deduction Family-building, fertility, adoption and surrogacy benefits Dental (including orthodontic coverage) and vision plans, both have options with a $0 paycheck contribution Company Paid (Health Savings Accounts) HSA Contribution when enrolled in the High-Deductible medical plan with HSA Healthcare and Dependent Care Flexible Spending Accounts (FSA) 401(k) with employer match, Employee Stock Purchase Plans, and other financial benefits Company paid Basic Life, AD&D Short-term and long-term disability insurance (90 day waiting period) Employee Assistance Program Sick and Vacation time (Flex time for salary positions, Accrued hours for Hourly positions), and Paid Holidays Back-up childcare and parenting support resources Voluntary benefits to include: critical illness, hospital indemnity, accident insurance, theft & legal services, and pet insurance Weight Loss and Tobacco Cessation Programs Tesla Babies program Commuter benefits Employee discounts and perks program Expected Compensation $111,200 - $200,160/annual salary + cash and stock awards + benefits Pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience. The total compensation package for this position may also include other elements dependent on the position offered. Details of participation in these benefit plans will be provided if an employee receives an offer of employment.
