Senior Embedded Software Engineer

About Tau Power conversion is the bottleneck between the compute, energy, and mobility industries and the future they're trying to build. Most of the industry is still solving it with decades-old approaches. Tau is fixing that. We're a venture-backed hardtech company in Redwood City, building power conversion technology for data centers, EVs, and energy systems. Several products are already moving into production. We hire people who own problems end-to-end: power electronics, embedded software, controls, test and validation, mechanical design. We solve from first principles, not legacy playbooks. We're past "promising technology." Customers are buying, volume is coming, and the people who join now set the standard everyone builds on after. About The Role Tau Motors seeks a highly skilled and experienced Senior Embedded Software Engineer to join our team. You will drive the development of Tau's cutting-edge software-enabled platforms through architecture, requirements, design, code, and testing. You will collaborate closely with cross-functional teams to define, develop, integrate, and test software functions, ensuring safe, robust, and efficient operation. Because our success depends on collaboration, we expect new employees to work onsite five days a week to build strong working relationships with the team. Our Engineering Approach Solve customer problems, not engineering puzzles. Great technical work becomes exceptional when it creates reliable products, enables meaningful new capability, and solves real customer problems. Think in systems. Understand how your work affects the complete product and the people who build it. Make tradeoffs that improve the whole, not just your direct area of ownership. Exercise judgment. Apply the engineering rigor the risk requires. Make timely decisions with the available evidence, communicate uncertainty, and balance technical excellence with program needs. Raise the standard. Deliver quality work on time, improve how the team works, and leave the products, systems, tools, and people around you better than you found them. What You'll Do Develop high-quality embedded code for real-time platforms, including motor controls and software-defined power electronics. Apply an excellent understanding of coding standards (MISRA) and functional safety (ISO 26262) to the software development process. Implement continuous improvement and development (CI/CD) practices within the software team and the larger organization. Work with multi-disciplinary teams to develop and integrate complex hardware/software systems. Collaborate with control engineers and technical domain experts to implement advanced algorithms and data structures in a testable, scalable, modular fashion. Deliver software architecture, create design requirements, and implement specifications while working with multiple stakeholders to develop robust and efficient power converters and systems. Develop software tests for a variety of test environments, including unit tests, software-in-the-loop (SIL), and Hardware-in-the-loop (HIL). Participate in code reviews and provide technical feedback to drive high-quality designs. What You’ll Bring A minimum of five years of hands-on industry experience and expert-level knowledge of embedded firmware development in C or C++ Familiarity with TI and Infineon MCUs Experience using debuggers, oscilloscopes, JTAG, logic analyzers, etc., digital bus (SPI, I2C, CAN, LIN, and Ethernet) with communication protocols (UDS, XCP, DOIP, and TCP/IP) Best practices and disciplines for software engineering, as well as hands-on experience with developing and troubleshooting embedded hardware and complex systems. Proven record in software product development for embedded systems with diverse and ambiguous requirements Ability to identify and resolve conflicting requirements Established experience with design and implementation for power conversion, motion control, and applications of hardware drivers for power electroni…
