Modular solid-state transformers for grid power
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 at scale.
Join us in building the power foundation of the future!
Role Summary
Amperesand is bringing solid-state transformer (SST) technology to market, and our first deployments at data centres and other critical sites will define how customers and partners see us. We are hiring a Staff Field Service Engineer – MV to be our lead medium-voltage expert in the field: the person who makes sure every installation is safe, repeatable and successful, and who builds the processes that let us scale beyond our own staff.
You will own the MV install, maintenance and RMA standard operating procedures and safety guidance, act as Technical Account Manager for key customers and partners, and lead installs at reference-critical pilot sites. You will also build and run our partner training and certification program so that qualified third-party installers can deploy Amperesand systems to our standard. Just as importantly, you will be the voice of the field in product design – feeding real-world installation, serviceability and reliability insight back to R&D, and freeing our engineering teams from day-to-day site work.
This is a Staff-level role with significant organizational impact. Over time you will build and lead a small, growing field service team and work closely with power electronics, firmware, software, hardware and operations engineers, as well as customers’ facilities and electrical teams. It suits someone who thrives in a startup: comfortable switching between hands-on site work and process building, willing to travel for extended periods, and driven by outcomes rather than hours.
Employment Type:
• Full-time
Location:
[San Francisco/South Bay Area / Reno]
Work Model:
• Onsite
Travel Requirements:
30%-50%
Onsite Collaboration Rationale:
Given the highly collaborative and cross-functional nature of hardware, embedded systems, and product development, in-person partnership across engineering and product teams is critical to enabling rapid execution, technical alignment, and successful development outcomes.
Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.
While this role is listed for the location above, we may consider candidates in other locations on a case-by-case basis.

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.
