Staff Hardware Validation Engineer
Owns the validation of high-voltage power electronics subsystems inside Amperesand's solid-state transformers, taking them from first bring-up through design validation, production ramp, and automated regression. Day-to-day is building HV/high-current test systems, characterizing efficiency and switching behavior, and automating tests with Python and systems languages.

Skills
Must have
- BS or MS in Electrical or Computer Engineering
- 6+ years hands-on experience in test, validation, or integration engineering, with substantial time on power electronics
- Demonstrated ownership of a product or subsystem through a full validation cycle, from first bring-up and design validation to production and sustaining regression
- Deep understanding of power electronics principles: switching converter topologies, magnetics, gate drive, control loops, high-voltage and high-current systems, and power conversion technologies
- Strong hands-on high-voltage lab skills and a rigorous, safety-first approach to working at power
- Solid experience with PCBA schematics and debugging hardware down to the component level
- Fluency with oscilloscopes, high-voltage differential probes, current shunts and Rogowski coils, power analyzers, multimeters, dielectric withstand testers, and thermal instrumentation such as thermoc
- Comfort with the data side of validation: structured results, dashboards, and statistical analysis
- Willingness to travel to different facilities worldwide to collaborate with teams and deploy solutions
Nice to have
- Experience with grid-tied inverters and active front ends, or DC fast charging
- Familiarity with partial discharge, dielectric withstand, and insulation coordination against standards such as IEC 61800-5-1, UL 1741, or IEEE 1547
- SiC or GaN device characterization, including double-pulse testing, switching loss measurement, and short-circuit behavior
- EMC pre-compliance testing
- Grounding and shielding design for fast-switching systems
- HALT/HASS, accelerated life testing, or reliability engineering exposure
- Experience using system-level languages (such as Golang, Rust, C, C++) to automate systems, along with Python for instrument control and data analysis

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
At Amperesand, you own validation of the power electronics that go into our solid-state transformers. As the technical validation lead for a major SST subsystem, you will take it from first bring-up through design validation, qualification, and continuous regression: building the test systems, defining the strategy, and holding the bar for what it means for high-power, high-voltage hardware to work flawlessly.
Responsibilities
- Serve as the technical validation lead for an assigned SST subsystem, owning the validation strategy, plan, and schedule from initial design validation through production ramp and sustaining releases.
- Design, develop, and maintain test systems for high-voltage, high-current power electronics, including load banks, source/sink and back-to-back converter setups, and thermal chambers.
