Reliability Test

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.

Reliability Test & Failure Analysis Technician

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.

Position Summary

We are seeking a hands-on Reliability Test & Failure Analysis Technician to support environmental, mechanical, electrical, and long-duration reliability testing of power electronics assemblies used in Solid State Transformer (SST) systems. This role is responsible for preparing test samples, building and maintaining test fixtures, operating environmental and vibration test equipment, monitoring long-term reliability tests, documenting results, and supporting failure analysis activities.

The ideal candidate is detail-oriented and experienced with power electronics hardware, environmental chambers, vibration systems, laboratory instrumentation, and test equipment. The technician will work closely with Reliability, Failure Analysis, Quality, Manufacturing, and Facilities teams to execute reliability qualification, burn-in, and operational reliability testing.

Key Responsibilities

Reliability Test Setup & Sample Preparation

• Prepare, inspect, document, and track test samples including PSM boards, and critical sub-assemblies and systems.
• Perform board bring-up, functional verification, pre- and post-test inspections, and hardware teardown activities.
• Maintain sample traceability, collect measurements, capture photographs, and document hardware condition before, during, and after testing.
• Coordinate rework and return of hardware to engineering teams for analysis.

Test Fixtures & Equipment Support

• Build, modify, maintain, and improve reliability test fixtures and support equipment.
• Install, verify, and maintain power supplies, thermocouples, temperature, and humidity sensors, and data collection equipment.
• Support burn-in and Operational Reliability Test (ORT) development through fixture improvements, repeatability verification, and sample processing.

Environmental & Reliability Testing

• Operate environmental chambers, vibration systems, and reliability test equipment supporting Temperature Cycling, THB, Condensation, HTOL, RDT, and other qualification tests.
• Perform safety reviews, functional verification, and ensure hardware remains within approved operating limits throughout testing.
• Install test samples and instrumentation, verify fixture integrity and torque requirements, and conduct pre- and post-test inspections.
• Monitor test progress, record alarms, excursions, downtime, interruptions, and time-at-condition data, and document anomalies.
• Assemble, operate, and maintain SST reliability test systems, including power, cooling, i
