Electrical Design Engineer

Summary

Armada builds ruggedized, modular, containerized data centers that deliver high-density AI compute to locations where traditional data centers cannot go. The Electrical Design Engineer will own electrical designs for modular units from single-line diagrams through commissioning, review vendor submittals, support manufacturing and deployment teams, and contribute to compliance, documentation, commissioning, and troubleshooting.

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

Skills

• US Citizen
• Bachelor's degree in Electrical Engineering from an accredited program
• 3–7 years of post-degree experience in electrical design, with at least 2 years in data centers, mission-critical facilities, industrial power, or equivalent complex power distribution
• Demonstrated working knowledge of the NEC (NFPA 70) and, ideally, one or more IEC-based national codes
• Hands-on experience with protection coordination and arc flash software (SKM PowerTools, ETAP, EasyPower, or similar)
• Proficiency with AutoCAD Electrical and/or Revit MEP, plus Bluebeam Revu (or equivalent) for submittal markup
• Familiarity with UPS systems (double-conversion topology, battery sizing, parallel operation), medium- and low-voltage switchgear, transformers, and generator/ATS integration
• Ability to read mechanical and structural drawings well enough to catch interdisciplinary conflicts before they hit manufacturing
• Clear written communication. You will be writing RFI responses, submittal reviews, and technical memos read by vendors and executives
• PE or EIT licensure is a plus; neither is required
• Experience with containerized or modular/prefabricated data center products
• Knowledge of high-density liquid-cooled GPU systems and their electrical implications — inrush, harmonics, rack-level power distribution, busway
• Working familiarity with battery chemistries beyond VRLA and lithium-ion, and with UL 9540A or equivalent large-scale battery testing requirements
• Familiarity with NFPA 70E, NFPA 75/76, NFPA 110, and NFPA 855 as they apply to mission-critical and energy storage installations
• Experience coordinating with multiple AHJs and international insurance bodies on mission-critical approvals
• Exposure to BMS/DCIM integration, BACnet/Modbus, and the electrical side of controls handoffs
• Experience working with external manufacturing partners and consultants across multiple time zones
