Firmware Manager

Company Overview

Amperesand is reinventing how the world powers its most critical systems. We are facing a once-in-a-generation opportunity for infrastructure disruption. Electricity demand is skyrocketing, driven by AI factories, electric vehicles, and modern industrial growth. Energy supply is shifting to incorporate a more diverse mix of resources – including solar, gas, and batteries – at a massive scale. And yet the power infrastructure behind our latest mega-projects hasn’t meaningfully changed in nearly 100 years.

Supply chains for today’s infrastructure equipment can’t match the pace and sophistication of critical energy projects. Amperesand is building hardware and software that rewrites this broken power infrastructure playbook to support a new era of energy abundance. We’ve built a new class of intelligent, software-defined power infrastructure products leveraging a decade of advanced medium voltage Solid State Transformer research that’s now ready for commercial deployment.

Our products and solutions go far beyond the capabilities of traditional electrical equipment. We make power systems that are faster to deploy, dramatically smaller and more efficient, and capable of supporting modern, dynamic energy needs for tomorrow’s most demanding energy consumers. Scalable in-house advanced manufacturing capability is our foundation for meeting timeline and quality expectation to serve infrastructure customers around the world.

Amperesand is led by breakthrough energy hardware development veterans and funded by top tier investors who share our vision of building a category-defining energy technology company. With hubs in San Francisco, Reno, and Singapore, our global team is laser focused on building foundational technology to solve the most pressing problems in power infrastructure n us in building the power foundation of the future!

We are looking for a Firmware Manager to lead and grow the embedded software team responsible for the control, safety, and communication firmware that powers our converters and solid-state transformer platforms. You will guide technical architecture, drive execution across multiple product lines, and build a team that consistently delivers high‑reliability embedded systems. This role is hands‑on: you will both manage engineers and contribute to design, code reviews, system bring‑up, and debugging of real hardware.

This role is ideal for someone who thrives at the intersection of firmware, power electronics, and product leadership.

• Own the architecture, implementation, and quality of all firmware running on our converter and SST platforms.
• Lead firmware design reviews, safety analyses, and high‑level technical decisions.
• Partner closely with Controls, Power Electronics, Electrical, and Systems teams to translate product and system requirements into clear firmware specifications.
• Guide firmware architecture across multiple MCU platforms.
• Establish best practices for embedded development—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: oscilloscopes, UART/SPI/I2C debug, 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 high‑performing firmware engineering team.
• Create growth paths, set expectations, and provide regular feedback.
• Build a culture of ownership, collaboration, and technical curiosity.
• Foster strong cross‑team communication and requirements traceability.

• 7+ years developing embedded firmware in C/C++ for real‑time systems.
• 2+ 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…
