Sr Staff Embedded Systems Engineer - Firmware

Stormentum Inc•Austin, TX

About The Position

Stormentum is hiring a Sr Staff Embedded Systems Engineer to join its firmware team and work closely with hardware, controls, and modeling groups. The role centers on real-time controls for the company’s power-conversion platform. The engineer will implement novel algorithms for modular multilevel converters, develop safety and fault handling, and build communication between modules and external systems. The position offers end-to-end ownership of firmware that runs on real hardware, with engineering decisions influencing product performance and field reliability. Stormentum builds power infrastructure for AI data centers, EV charging, and microgrids. Its patented modular power-electronics architecture combines UPS, battery, and rectifier stages into one platform. The company offers a competitive compensation package including base salary and equity, along with medical, dental, vision, and life insurance, a 401(k), flexible time off, and paid holidays. Stormentum is an equal opportunity employer and provides reasonable accommodations during the interview process.

Requirements

Bachelor’s or master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a similar field.
At least 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.
Ability to bring up boards, probe signals, and debug 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.

Nice To Haves

Specialization in power electronics.
Familiarity with decentralized controls for interconnected systems.
Familiarity with Modular Multilevel Converters (MMCs).
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.

Responsibilities

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 in collaboration with 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 debugging 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 control information and telemetry used in system monitoring.
Lead firmware design reviews and contribute to safety analyses such as HARA and DFMEA.
