Electrical Design Engineer

About the Company

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.

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.

Required Qualifications

• 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. Multi-jurisdictional design experience is a strong plus.
• 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.

Preferred Experience and Skills

• 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.

Citizenship Requirements

For select roles, due to the nature of our clientele and the technologies involved, there may be specific nationality or citizenship indicated in the required qualifications section. These roles may involve access to sensitive information that is subject to export control regulations or other legal restrictions. In such cases, employment offers will be contingent upon your ability to comply with these requirements.
