Armada is a hyperscaler for edge AI infrastructure, delivering modular, ruggedized, containerized data centers that bring high-density AI compute to remote and sovereign locations globally. The company has raised nearly $500M from top-tier investors including Founders Fund, Lux, BlackRock, and Microsoft, with strategic partnerships across Microsoft, Dell, Palantir, NVIDIA, SpaceX, and Skydio.
As an Electrical Design Engineer, you will work directly under the Senior Electrical Design Engineer on the power and integration team. This is a hands-on role focused on shipping hardware, not producing reports. You will own electrical design for modular containerized data center units from single-line diagrams through commissioning, working across multiple international markets with deployments ranging from multi-megawatt GPU clusters to large-scale multi-unit campuses at up to 400 kW/rack.
Key responsibilities include:
• 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 (480V and international LV systems).
• Run protective device coordination, arc flash, and short-circuit studies using SKM, ETAP, or equivalent tools. Produce labels and coordination reports for field use.
• 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 specifications and flag discrepancies early.
• Support manufacturing partners across multiple time zones: answer RFIs, resolve conflicts on layout and piping/cable routing, and participate in factory witness testing.
• Contribute to multi-jurisdictional compliance across international electrical, fire, and mission-critical facility codes. Coordinate with local Authorities Having Jurisdiction.
• Produce clear engineering documentation including Statements of Requirements, design basis memos, block diagrams, and commissioning procedures.
You will be on calls with manufacturers early in the morning, reviewing arc flash studies at noon, and answering field questions from commissioning crews in the evening. This role requires someone who thrives in a fast-paced, hardware-shipping environment with direct impact on global deployments.
