Sr Staff Embedded Systems Engineer - Firmware

At Stormentum you’ll join the firmware team, working closely with the hardware, controls, and modeling groups. The real-time controls that make the converter run sit at the heart of the platform. You’ll implement novel algorithms for modular multilevel converters, develop safety and fault handling, and build communication between modules and with the outside world. You’ll see your own code run on real hardware rather than maintaining legacy code, and own it end to end. The decisions you make shape how the whole product performs and how reliably it holds up in the field.

What You’ll Do

• Implement and test novel control algorithms for modular multilevel converters
• Develop PWM controls that minimize system-level harmonics
• Translate system and controls requirements into firmware specifications, working closely with the controls, hardware, and systems teams
• Work with the modeling team to keep models aligned with the current firmware implementation and simulation waveforms matched to the real system
• Build debug capabilities to diagnose issues in the lab, in the field, and in manufacturing, and to validate signal sensing and controls
• Design communication protocols for timing-critical controls information and for telemetry used in system monitoring
• Lead firmware design reviews and contribute to safety analyses such as HARA and DFMEA

• A BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or a similar field (specialization in power electronics a plus)
• 7+ years of experience developing and implementing power electronics or motor control systems, including at least two full product cycles taking distinct products to market
• Proficiency coding in C for microcontrollers in timing-critical, bare-metal applications, using interrupt-driven or lightweight RTOS architectures
• Deep understanding of microcontroller architecture, including interrupts, DMA, peripherals, and bootloaders
• Comfort bringing up boards, probing signals, and debugging real hardware using oscilloscopes, logic analyzers, and JTAG debuggers
• Experience with CAN, RS-485, SPI, I2C, or other communication protocols
• Experience with version control, CI/CD, and firmware release processes
• Experience developing safety-related firmware in compliance with processes outlined in UL 1998, UL 991, and IEC 61508

What Will Make You Stand Out

• Familiarity with decentralized controls for interconnected systems
• Familiarity with Modular Multilevel Converters (MMCs) a plus
• Experience implementing grid-support functions such as ride-through, volt-var, and frequency-watt in firmware to meet UL 1741 SA/SB and IEEE 1547
