Senior Manager-System Electronics

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 at scale.

Join us in building the power foundation of the future!

Amperesand is building next-generation power infrastructure systems for Data Centers, EV charging platforms, and future energy applications. Our systems combine advanced power electronics, embedded controls, and scalable energy architectures to rethink how power is converted, controlled, and deployed.

Role Summary

At Amperesand, the System Electronics leader owns the system-level electronics architecture of our Solid-State Transformer (SST) products. You will lead a team of design engineers who architect and develop the low-voltage and mixed-signal control, sensing, safety systems, and auxiliary power converters. You own how these subsystems are partitioned, how they interface across voltage domains, and how they come together into designs that are safe, reliable, manufacturable, and cost-effective across prototype, pre-production, and volume production.

You will partner closely with the program management team and cross-functional teams to bring rigor, speed, and architectural clarity to everything we ship.

Responsibilities

• Own the end-to-end system-level electronics architecture for SST products.
• Define the low-voltage and mixed-signal architecture for control, sensing, and protection, ensuring measurement chains, fault detection, and communication interfaces meet performance and safety targets.
• Set architectural direction across the system: functional partitioning, interface definition, voltage-domain isolation, grounding, protection, redundancy, and fault tolerance to meet single-fault-tolerant and product-lifetime requirements.
• Define the 800V power architecture and set direction on auxiliary power converter architecture: topology strategy, power budgeting, isolation, and integration with the SST power stage.
• Lead, mentor, and grow a team of design engineers. Provide technical guidance while empowering engineers to own…
