Armada is a hyperscaler for edge AI infrastructure, delivering modular, ruggedized, containerized data centers for sovereign and edge AI deployments across 60+ countries. The company is backed by ~$500M in funding from Founders Fund, Lux, BlackRock, and Microsoft (M12), with strategic partnerships including Microsoft, Dell, Palantir, NVIDIA, SpaceX, and Skydio.
You will join the power and integration team as an Electrical Design Engineer, reporting to the Senior Electrical Design Engineer. 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 directly with manufacturing partners and deployment teams across multiple time zones.
Key Responsibilities:
- Develop and maintain electrical designs for modular data centers: single-line diagrams, load calculations, panel schedules, grounding, cable sizing, and raceway layouts across 480 V and international low-voltage distribution standards.
- Run protective device coordination, arc flash, and short-circuit studies using SKM, ETAP, or equivalent software; 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.
- Support manufacturing partners by answering RFIs, resolving layout and routing conflicts, and participating 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: Statements of Requirements, design basis memos, block diagrams, and commissioning procedures.
- Collaborate with mechanical, controls, structural, and fire protection engineers; push back when something is wrong regardless of seniority.
- Support field commissioning and troubleshooting, including occasional international travel to manufacturing 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 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 manufacturing
- Clear written communication for RFI responses, submittal reviews, and technical memos read by vendors and executives
Preferred Experience:
- PE or EIT licensure
- Experience with containerized or modular/prefabricated data center products
- Knowledge of high-density liquid-cooled GPU systems and their electrical implications
- Working familiarity with battery chemistries beyond VRLA and lithium-ion, and 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 electrical controls handoffs
- Experience working with external manufacturing partners and consultants across multiple time zones
