Staff Field Service Engineer

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!

About the Role

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.

What You’ll Do

Responsibilities

• Own MV service procedures and safety: Author, own and continuously improve MV installation, commissioning, maintenance and RMA SOPs, including safety guidance, LOTO/switching procedures and arc-flash practices aligned with NFPA 70E.
• Lead pilot site installs and ongoing maintenance: Lead and personally deliver safe, on-time installations and commissioning, and ongoing maintenance, at reference-critical pilot sites, including data centres, achieving zero safety incidents, 99.999% availability and first-time-right energization.
• Act as Technical Account Manager: Serve as the primary technical point of contact for key customers and partners – managing site readiness, escalations, root-cause investigations and service reviews to drive uptime and customer satisfaction.
• Build partner certification: Design and deliver a training and certification program that enables effective training of in-house or external installers to deploy and maintain Amperesand systems at scale, and audit their work to Amperesand’s standards.
• Be the voice of the field in product design: Capture field learnings and translate them into clear, prioritized design inputs (via Jira) for serviceability, installability and reliability; participate in design reviews as the field representative.
• Drive diagnostics and RMA: Use system telemetry and field data to diagnose faults, support RMA failure analysis with R&D, and identify trends that improve fleet reliability.
• Build and lead the field team: Hire, mentor and lead a team of field service engineers/technicians, setting standards for safety, documentation and customer conduct.
• Be a hands-on generalist: Contribute wherever needed in a startup environment – from site surveys and tooling to spares planning and service pricing input.

What You’ll Bring

Required Qualifications

• Years of experience: 10+ years in field service, commissioning or installation engineering, with substantial hands-on MV (e.g. 4.16–35 kV) switchgear, transformer or power conversion equipment experience.
• Education: BSc in Electrical Engineering or a related discipline, or equivalent practical experience (e.g. military, utility or trade background).
• Domain expertise: Deep knowledge of MV systems, protection, switching, grounding and safe work practices; current NFPA 70E / arc-flash training.
• Leadership: Experience leading or mentoring field teams, and authoring SOPs, training material or certification programs.
• Industry experience: Data centre, mission-critical facility, utility or energy infrastructure experience strongly preferred.
• Flexibility: Willingness to travel 30–50%, including multi-week deployments, and to work extended or irregular hours when site schedules demand.
• Collaboration: A team player who communicates clearly with customers and with software, electrical and hardware engineers alike.

Technical Skills

• MV switchgear, transformers, protection relays and power distribution architecture
• Familiarity with power electronics (inverters, converters, UPS or SST systems) and their commissioning
• Basic understanding of telemetry, SCADA/BMS/monitoring systems and using data to troubleshoot
• Jira (or similar) for issue tracking and feeding field feedback into engineering
• Test equipment: insulation resistance/hipot testers, power quality analyzers, oscilloscopes, multimeters, relay test sets
• Reading and marking up single-line diagrams, schematics and installation drawings
• Knowledge of relevant codes and standards (NEC, NFPA 70E, IEEE, UL/IEC)

Nice to Have

• Startup or early-stage product deployment experience
• NETA Level III/IV certification
• OSHA 30 certification
• Experience with solid-state transformers, power electronics converters or grid-tied energy storage
• Experience building technical training or partner/installer certification programs
• Basic scripting (e.g. Python) for data analysis or test automation
