Power Electronics Firmware Engineer
New Yesterday
We are looking for a Power Electronics Firmware Engineer with experience in power electronics control and real-time embedded systems to work closely with power electronics engineers, control engineers, and electrical engineers. You will be responsible for implementing, testing, and optimizing firmware for our mass-produced battery storage systems, ensuring safety, reliability, and compliance with regulatory standards.
This role is ideal for someone who has taken products from prototype to mass production and understands the complexities of safety-critical embedded software in a regulated environment.
Responsibilities:
- Develop real-time firmware for power electronics control, including inverter control, battery, and grid interconnect algorithms.
- Work closely with power electronics and control engineers to implement DSP/Microcontroller-based control algorithms (e.g. PWM, phase-locked loops, active/reactive power control).
- Ensure firmware meets safety-critical requirements for regulatory compliance (e.g., UL 1741, IEEE 1547, ISO 26262).
- Collaborate with power electronics hardware and control engineers throughout the development cycle (sensor selection, validation, and hardware improvements).
- Interface with hardware and electrical engineers to integrate firmware with custom PCBs and power conversion systems.
- Implement and refine diagnostics, fault detection, and recovery mechanisms to improve system uptime and reliability.
- Conduct hardware-in-the-loop (HIL) testing, embedded simulation, and field validation to verify firmware performance.
- Develop bootloaders, over-the-air (OTA) update mechanisms, and secure firmware signing for fleet management.
- Debug firmware issues in prototype and production environments, using oscilloscopes, logic analyzers, and serial debugging tools.
- Document firmware architecture, control logic, and regulatory compliance considerations.
Required Skills / Qualifications:
- 5+ years of experience in embedded firmware development, with a focus on power electronics, inverters, or motor control.
- Strong experience with C/C++ for embedded systems, including real-time constraints, memory management, and debugging.
- Experience developing real-time control algorithms for inverters, converters, or battery systems.
- Familiarity with digital signal processing (DSP), microcontrollers, and FPGA-based control.
- Experience working in a safety-critical, regulated environment (e.g., UL, IEC, ISO standards).
- Hands-on experience with embedded software debugging tools (oscilloscopes, JTAG, logic analyzers).
- Strong understanding of power electronics principles, including modulation techniques (PWM, SVM), power factor correction, and grid synchronization.
Preferred Qualifications:
- Experience with mass production firmware development for battery storage, inverters, or industrial power systems.
- Experience with hardware-in-the-loop (HIL) testing, MATLAB/Simulink, or model-based design.
- Familiarity with ARM Cortex-M, TI C2000, STM32, or similar microcontroller families used in power control.
- Knowledge of embedded cybersecurity practices, including secure bootloaders and firmware updates.
- Experience with CAN, SPI, I2C, and Modbus communication protocols for power electronics integration.
- Understanding of fleet management for distributed energy systems.
If you're passionate about tackling one of the most critical challenges of our time, now is the time to join us. Together, we can usher in a new era of American energy abundance by developing the hardware, software, and deployment operations that make it possible.
Our Values:
We're building a winning culture, and we're looking for people who are up for the challenge. These are the values we expect you to embrace from day one:
- In-Person Work: We work full-time in the office. There is no hybrid or remote work.
- Challenge Assumptions: We're not here to do things the way they've always been done. We look for people who question the status quo and improve broken systems. We are guided by principles, not rules.
- Operate with Urgency: Speed matters. We focus on what's essential, make fast progress, and iterate quickly. Execution drives learning, and learning drives impact. Always have a bias for action.
- Give & Seek Feedback: We value intellectual honesty. We expect you to challenge ideas (even your own), give direct feedback, and receive it with humility.
- Deliver: We are high achievers with a drive to win. We take end-to-end accountability for seeing our work through and delivering on our responsibilities.
- Think Like an Owner: We are all owners of the business. We use our time and resources wisely and take personal responsibility for our impact on the bottom line.
- Be Opinionated: Great people make decisions with imperfect information. Eliminate murky ownership and drive towards decisions.
- Bring the Intensity: This is not a 9-to-5 job. We are building something hard, and that requires real commitment.
- Location:
- Austin
