Senior Data Center Commissioning Engineer

About this role

About the Company

Armada is the hyperscaler for the edge, delivering modular AI infrastructure from first deployment to AI factory with speed, scale and sovereignty. Named one of Fast Company's Most Innovative Companies and to the CNBC Disruptor 50, Armada’s solutions are deployed in over 60 countries globally for organizations ranging from energy to defense.

With nearly $500 million in funding to date, Armada is backed by leading investors including Founders Fund, Lux, BlackRock and Microsoft (M12), alongside strategic partnerships with Microsoft, Dell, Palantir, NVIDIA, SpaceX, and Skydio. We are building the infrastructure layer for sovereign and edge AI - rugged, deployable compute for customers that cannot rely on centralized cloud.

Working at Armada means taking ownership, driving autonomy, and delivering impact. You’ll tackle challenges that haven’t been solved before and help build something transformative from the ground up. What you do here will not only define your career but help further Armada’s mission to bridge the digital divide for customers around the world.

About the Role

Armada is hiring a Senior Data Center Commissioning Engineer to support the Galleon, Leviathan, and Orion product lines, a brand-new capability for the company. As we scale Modular Data Center (MDC) deployments for AI workloads across a growing number of sites, we need someone who can own the commissioning thread that runs from factory acceptance testing through site start-up, functional testing, Integrated Systems Testing (IST), and handover to operations, and make sure every system performs as designed before a customer takes over.

You will build Armada's commissioning program from the ground up: the commissioning plan, test scripts, and turnover standards for Level 1 through Level 5 commissioning across MV/LV electrical distribution, UPS and battery energy storage (BESS), liquid and air cooling, BMS/EPMS controls, and fire and life safety systems. Because our products are factory-built, you'll push as much testing as possible into the factory, so units arrive on site pre-tested and site commissioning focuses on integration and verification. This is a hands-on senior IC role. You'll write the procedures, lead the tests, and be the commissioning point of contact for customers, third-party commissioning agents, contractors, and OEM vendors, while feeding what you learn back into product engineering.

Location. Remote, USA (approximately 40–50% travel to domestic and international project sites, factory/integrator facilities, and vendor locations)

What You'll Do (Key Responsibilities)

• Commissioning program and standards: Build and own Armada's commissioning program to industry standard (the ASHRAE Guideline 0 and Standard 202 commissioning process and the industry-standard Level 1 through Level 5 testing framework), including the commissioning plan, OPR/BOD alignment, pre-functional checklists, functional performance test scripts, IST procedures, and turnover requirements, so every Galleon/Leviathan/Orion deployment commissions against one repeatable playbook instead of a one-off plan per site.

• Factory acceptance testing: Define and lead factory acceptance testing (FAT and integrated FAT of complete modules) at integrator and vendor facilities for modules, e-houses, skids, and major equipment (switchgear, UPS, BESS, CDUs, chillers, controls), shifting testing into the factory so units arrive on site pre-tested and ready to integrate.

• Site commissioning through IST: Lead receipt inspection, pre-functional checks, start-up, functional performance testing, and Integrated Systems Testing on active sites, including load bank testing, failure-mode and transfer scenarios, liquid-cooling flushing and fluid quality verification, and GPU load step and ramp-rate behavior, owning the issues log through closure.

• Hands-on testing and troubleshooting: Personally write test procedures, witness and run tests, analyze trend and power quality data, and troubleshoot failures across electrical, mechanical, and controls systems, particularly on first-of-a-kind products and sites where no precedent exists yet.

• Customer, CxA, and vendor coordination: Act as the commissioning point of contact for customers, third-party commissioning agents, general contractors, and OEM vendors; coordinate witness schedules and readiness reviews, direct vendor start-up activities, and align commissioning scope with the Armada/customer responsibility matrix.

• Turnover, operational readiness, and product feedback: Own turnover packages (test records, as-builts, O&M manuals, warranties, training) and the final commissioning sign-off for operational handoff, and feed failures, lessons learned, and test data back into product engineering so each product generation commissions faster than the last.

Required Qualifications

• Bachelor's degree in Electrical or Mechanical Engineering (or related field), or equivalent hands-on commissioning experience.

• 8+ years of commissioning experience on mission-critical facilities, including at least 5 years on data center projects and hands-on leadership of Level 4 and Level 5 commissioning (functional performance testing and IST).

• Deep, hands-on commissioning expertise in either electrical systems (MV/LV switchgear, UPS, BESS, transfer schemes, generators, protective relaying) or mechanical and controls systems (chillers, air handling, liquid cooling and CDUs, BMS/EPMS sequences), with strong working knowledge of the other.

• Working knowledge of commissioning standards and codes (ASHRAE Guideline 0 and Standard 202, NETA ATS, NFPA 70/70E, NFPA 72) and Uptime Institute methodologies.

• Experience writing commissioning plans, test scripts, and turnover documentation, not only executing them.

• Comfort operating with a high degree of autonomy. You'll be defining the playbook, not inheriting one.

• Willingness and ability to travel approximately 40–50% to project sites,…
