 * 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

## Description

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
