Engineering Technician - Power Electronics Validation

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! Responsibilities Support the build and modification of prototype units, including electrical harnessing, mechanical assembly, and part rework. Partner with engineers to design and improve lab infrastructure, test setups, and safe workflows. Execute lab build‑out. Assemble PCBs, including soldering surface‑mount and through‑hole components. Perform expert‑level rework, including fine‑pitch components and BGA packages. Assemble complex test setups involving electrical wiring, fluid plumbing, and mechanical integration. Ensure setups are robust, repeatable, and safe. Collaborate with design, validation, and reliability engineers to support test planning, execution, and troubleshooting. Provide feedback to improve product design and test efficiency. Perform electrical and mechanical testing on high‑voltage power converters, following detailed test procedures and safety protocols. Interpret engineering drawings and schematics to support builds. Own organization, cleanliness, and safety of the lab space. Ensure all tools, equipment, and test stations are calibrated, functional, and compliant with safety standards. Coordinate ordering, receiving, and tracking of components and consumables. Maintain inventory of critical lab supplies and test equipment. Challenge ideas and decisions with reasoning from first principles. Travel to different facilities worldwide to collaborate with teams and deploy our solutions. Qualifications Diploma or Associate degree in Electrical Engineering Technology or equivalent hands‑on experience. 3+ years in a lab or R&D environment, preferably working with high‑voltage or power electronics systems. Strong understanding of electrical schematics, wiring diagrams, and technical manuals. Basic mechanical aptitude – comfortable with plumbing, fluid systems (e.g. chillers, pumps), assembling enclosures and fixtures. Advanced soldering and PCB rework skills, including experience with reflow and hand soldering techniques. Strong organizational skills and attention to detail in documentation and setup execution. Familiarity with test instrumentation (oscilloscopes, power analyzers, DAQs). Experience in prototype rework, soldering, and mechanical fabrication. Proficient in crimping and harness fabrication. Knowledge of lab safety standards and electrical safety certifications (e.g. NFPA 70E). Certifications in OSHA, LOTO (Lockout/Tagout), or HV Safety Certification preferred. Ability to lift 20–40 lbs daily and maintain a safe, clean working environment. Be engaged, proactive, and positive when taking on challenging tasks, owning assignments, and taking accountability for personal and overall team success.
