Electrical Design Engineer

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 builds and deploys ruggedized, modular, containerized data centers that bring high-density AI compute to locations where traditional data centers cannot go. We are scaling production across multiple international markets, with deployments ranging from multi-megawatt GPU clusters to large-scale multi-unit campuses at up to 400 kW/rack. Armada needs an Electrical Design Engineer to work directly under the Senior Electrical Design Engineer on the power and integration team. This is a hands-on design role: you will own the electrical design for modular units from single-line through commissioning, review vendor submittals, and directly support manufacturing partners and deployment teams across multiple time zones. You will not be writing specs from an ivory tower — you will be on calls with manufacturers early in the morning, reviewing arc flash studies at noon, and answering field questions from a commissioning crew in the evening. This role is for someone who wants to ship hardware, not produce reports. Location. This role is remote. What You'll Do (Key Responsibilities) • Develop and maintain electrical designs for modular containerized data centers: single-line diagrams, load calculations, panel schedules, grounding, cable sizing, and raceway layouts across multiple low-voltage distribution standards (480 V and other international LV systems). • Run protective device coordination, arc flash, and short-circuit studies in SKM, ETAP, or equivalent. Produce labels and coordination reports that will be used in the field. • Review and redline vendor submittals for UPS systems, battery systems, cooling distribution units, switchgear, main distribution boards, PDUs, and generator/ATS packages. Hold vendors accountable to the spec; flag discrepancies early. • Support manufacturing partners: answer RFIs, resolve conflicts on layout and piping/cable routing, and participate in factory witness testing. • Contribute to multi-jurisdictional compliance across a range of international electrical, fire, and mission-critical facility codes, and coordinate with local Authorities Having Jurisdiction. • Produce clear engineering documentation: Statements of Requirements, design basis memos, block diagrams, and commissioning procedures. If you hate writing, this is not the job. • Work alongside mechanical, controls, structural, and fire protection engineers — and with external consultants. You will be expected to push back when something is wrong, regardless of seniority. • Support field commissioning and troubleshooting, including occasional international travel to manufacturing partner sites, deployments, and trade events.
