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 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 the safe, robust, and efficient operation.

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.
• Experience seeing a product through its full software development lifecycle, including verification, validation, and maintenance of architecture, test, and deployment phases.
• 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, and 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

• Expert-level knowledge of embedded firmware development in C or C++
• Strong communication skills, a preference for working in teams, and a passion for delivering high-quality outcomes
• 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, including identifying and resolving conflicting requirements.
• Established experience with design and implementation for power conversion, motion control, and applications of hardware drivers for power electronics
• Familiarity with TI and Infineon MCUs
• Knowledge of common lab equipment such as debuggers, oscilloscopes, JTAG, logic analyzers, etc., digital bus (SPI, I2C, CAN, LIN, and Ethernet) with communication protocols (UDS, XCP, DOIP, and TCP/IP)
• Experience developing and integrating Model Based Development tools (Simulink) and generated code with hand-written code by maturing architectures and interface descriptions.

Preferred Skills

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related degree
• 5 or more years of experience in embedded software engineering or a related discipline
• Fluency with C/C++ and Python
• Experience developing embedded software in a regulated environment, complying with safety standards such as ISO 26262.
• Excellent organizational and communication skills
• Experience with version control, configuration management, and software change control tools, including Git and Jira.

Desired Skills

• Familiarity with requirements-based testing and test automation with software-in-the-loop (SIL) and hardware-in-the-loop (HIL) environments
• Experience with both Real-Time Operating Systems (RTOS) and bare-metal embedded software development
• Experience with high-voltage and/or motor control systems.
• Experience developing and maintaining Continuous Integration (CI) tools such as Github Actions, Jenkins, or TeamCity
