Power Electronics Firmware Engineer

Mid- or Senior- Level | Battery Systems & Grid Innovation|Mission-Driven Energy Company

• San Francisco, CA
• Full-time, Direct Hire
• Up To $240,000 Base Salary + RSU Offerings
• Full Benefits Package

This company is on a mission to fix the power grid and make affordable, reliable electricity a reality for everyone. As a next-generation, engineering-led power company, They are rethinking how energy is delivered by combining deep technical expertise with cutting-edge R&D. They build battery-based systems that support the grid, enable renewable energy adoption, and provide dependable backup power during outages.

They are searching for aPower Electronics Firmware Engineerto help drive the development of intelligent, grid-connected battery platforms. This role is ideal for someone who’s taken complex embedded systems from concept to production and thrives at the intersection of hardware, firmware, and power electronics.

What You'll Be Doing:

• Develop real-time embedded firmware for power electronics systems, including inverter control and grid synchronization.
• Collaborate with control, hardware, and electrical engineers to implement DSP/microcontroller-based algorithms (PWM, PLLs, power factor control).
• Ensure firmware complies with regulatory and safety standards (e.g., UL 1741, IEEE 1547, ISO 26262).
• Build firmware for secure OTA updates, diagnostics, fault handling, and system reliability.
• Conduct hardware-in-the-loop (HIL) simulations and in-field validation to ensure performance and safety at scale.

What You Bring:

• Strong hands-on experience developing embedded C/C++ firmware in real-time environments, ideally within power electronics, motor control, or inverter systems.
• Deep understanding of power electronics principles, digital signal processing, and microcontroller-based control.
• Familiarity with safety-critical development environments and regulatory compliance frameworks.
• Skilled in debugging with oscilloscopes, logic analyzers, and embedded debugging tools.
• Comfortable working across hardware/firmware boundaries in fast-paced product development cycles.

Bonus If You Have:

• Experience taking battery or inverter firmware into mass production.
• Knowledge of model-based design (e.g., MATLAB/Simulink) and HIL testing.
• Familiarity with secure bootloaders, OTA firmware updates, and communication protocols (CAN, SPI, Modbus, I2C).
• Background in fleet management of distributed energy systems.
