About the Job

Requirements

  • At least 7 years developing embedded firmware in C/C++ for real-time systems.
  • At least 3 years managing or leading firmware teams.
  • Strong experience with real-time control systems, safety-critical firmware, or power electronics.
  • Deep understanding of microcontroller architectures, interrupts, DMA, peripherals, bootloaders, and RTOS environments.
  • Hands-on experience with oscilloscopes, logic analyzers, hardware bring-up, and debugging at the board and system level.
  • Experience with structured requirements (PRS/DRS), version control, CI/CD, and firmware release processes.
  • Strong communication skills and ability to collaborate across disciplines.

Responsibilities

  • Own the architecture, implementation, and quality of firmware running on converter and solid-state transformer platforms.
  • Lead firmware design reviews, safety analyses, and high-level technical decisions.
  • Partner with Controls, Power Electronics, Electrical, and Systems teams to translate product and system requirements into firmware specifications.
  • Guide firmware architecture across multiple microcontroller platforms.
  • Establish embedded development best practices, including coding standards, CI/CD, testing frameworks, branching strategies, and documentation.
  • Drive firmware delivery across multiple releases and hardware revisions.
  • Manage prioritization, sprint planning, and cross-functional alignment with Hardware, Controls, Systems, and Manufacturing teams.
  • Work directly with hardware during bring-up, including oscilloscopes, UART/SPI/I2C debugging, JTAG, power event testing, and system validation.
  • Own root-cause investigation for firmware-related issues in lab, field, and manufacturing environments.
  • Recruit, mentor, and develop a firmware engineering team.
  • Create growth paths, set expectations, and provide regular feedback.
  • Build a culture of ownership, collaboration, and technical curiosity.
  • Foster cross-team communication and requirements traceability.

Desired Qualifications

  • Familiarity with grid-connected systems.
  • Knowledge of safety standards (UL/IEC), high-voltage/medium-voltage systems, or safety-integrity-level-oriented firmware development.
  • Exposure to manufacturing test firmware.
  • Experience scaling firmware practices for multi-product hardware organizations.

About the Company

Amperesand

Modular solid-state transformers for grid power

Amperesand develops modular solid-state transformers (SSTs) for grid infrastructure using silicon carbide (SiC) devices and proprietary high-frequency transformers. The SSTs are digitally controlled and bidirectional, offered in 2, 4, and 6 MW modules that can be combined to meet larger needs, replacing traditional transformers, switchgear, and UPS in a single AI-driven system. It differentiates itself through the combination of SiC SSTs, proprietary high-frequency transformers, digital power management, and leadership from NTU R&D spun out with Temasek’s Xora Innovation, plus an experienced team from ABB, GE, Siemens, and Vestas. The goal is to speed up the energy transition by delivering scalable, compact SST systems for EV charging networks, microgrids, data centers, and industrial power, with first deliveries planned for 2025 in the US and Singapore.
