Electrical Engineer - Data Centers

FläktGroup is a global leader in energy-efficient air technology and mission-critical cooling solutions for data centers. The Senior Electrical Engineer will own the electrical design of data center cooling equipment from concept through production release and field commissioning, including UL 508A-compliant control panels, electrical calculations, schematic packages, and product standardization. The role also supports customer qualification, manufacturing, testing, documentation control, and field issue resolution.

Responsibilities:

• Develop complete electrical schematic packages — power distribution, motor/VFD circuits, control circuits, safety circuits, terminal plans, panel layouts, wire/cable schedules, and interconnection diagrams — using EPLAN Electric P8 and AutoCAD Electrical
• Design industrial control panels in full compliance with UL 508A, including panel layout, component selection, spacing/bending requirements, wire sizing and color coding, and nameplate/marking requirements
• Build and maintain EPLAN master data: symbol libraries, macros, article/parts databases, project templates, and title block standards to enable reusable, configurable standard designs
• Design power circuits for EC fan arrays, VFD-driven pumps and fans (Yaskawa and equivalent), transformers, control power supplies, UPS backup circuits, and heater loads across 120V–600V, single- and three-phase, 50/60 Hz systems
• Design low-voltage control and instrumentation wiring for Siemens Climatix (POL family) controllers, I/O extension modules, HMIs, sensors, safety relays, and BACnet/Modbus network segments, in coordination with the Controls Engineering team
• Design hardwired safety chains (HOA,E-stop, smoke detection, leak detection, external interlocks) with fail-safe, normally-closed architecture consistent with product safety standards
• Full Load Amps (FLA) and Minimum Circuit Ampacity (MCA) / Maximum Overcurrent Protection (MOP) calculations for complete units per NEC and UL 60335-2-40 / UL 1995 as applicable
• Short-Circuit Current Rating (SCCR) determination for control panels per UL 508A Supplement SB, including component ratings, series ratings, and current-limiting device application
• Conductor and cable sizing, ampacity derating, and voltage drop calculations per NEC Articles 310, 430, and 440 for branch circuits, feeders, motor circuits, and control wiring
• Overcurrent protection and coordination: fuse and circuit breaker selection, motor branch-circuit protection, transformer primary/secondary protection, and selective coordination analysis
• Transformer and control power supply sizing, including inrush, regulation, and load growth margin
• Panel heat load / thermal dissipation calculations and enclosure thermal management design (ventilation, cooling, heater sizing for condensation control)
• Motor and VFD sizing verification, harmonic considerations, and 50 Hz vs. 60 Hz parameter validation for equipment built
• Grounding and bonding design, wire pull and conduit fill calculations, and arc-flash awareness input where required
• Serve as document owner for assigned electrical standard documents within the controlled document register; author, revise, and release standards through formal review gates
• Classify all electrical design elements as Fixed, Configurable, or Project-Specific (F/C/P) and enforce this classification during project execution to prevent uncontrolled design drift
• Convert legacy outsourced drawing sets into in-house, controlled EPLAN standard packages; perform gap analyses between existing drawings, PRDs, BOMs, and customer specifications
• Develop and maintain standard BOMs with approved component libraries (Siemens, Yaskawa, Phoenix Contact, ABB, and others), including alternates and lifecycle/obsolescence tracking
• Support US–India engineering collaboration, including drawing standards alignment, EPLAN license sharing workflows, and re-certification checklists for IEC/CE-built units deploying to US sites (frequency, protocol defaults, wireless restrictions, unit conventions)
• Review customer specifications, guide specs, and hyperscaler qualification requirements and translate them into compliant electrical designs; identify and formally document deviations
• Produce submittal-quality drawing packages and respond to customer and consultant review comments with documented engineering justification
• Provide technical direction to external drafting partners and panel builders; review and approve vendor drawings, panel layouts, and as-built documentation
• Support Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT): develop electrical test procedures, witness testing, disposition non-conformances, and drive corrective actions
• Provide root-cause analysis and engineering disposition for field electrical issues, manufacturing deviations, and supplier quality escapes
• Manufacturing plant visits (US and international facilities) for design support, first-article inspection, and production issue resolution
• Panel builder and supplier facility visits for design reviews, quality audits, and FAT witnessing
• Customer data center sites for SAT support, commissioning assistance, and field issue investigation
• Customer and consultant offices for design review meetings and qualification activities

Requirements:

• Bachelor of Science in Electrical Engineering (or closely related field) from an accredited program
• 8+ years of electrical design experience in industrial equipment, HVAC/mechanical equipment, control panels, or mission-critical infrastructure
• Expert-level proficiency in EPLAN Electric P8 — including project structuring, macro development, article management, and cross-referencing — and strong working proficiency in AutoCAD Electrical
• Demonstrated ownership of UL 508A panel designs, including SCCR calculations per Supplement SB; UL 508A MTR certification or ability to obtain within 6 months
• Strong command of the NEC (NFPA 70), particularly Articles 310, 409, 430, and 440, and the ability to perform and document all supporting calculations independently (FLA/MCA/MOP, voltage drop, conductor sizing, protection coordination, transformer sizing, panel heat load)
• Hands-on experience with VFDs, EC motors, three-phase power distribution, control transformers, and 24V control architectures
• Experience producing complete, production-ready drawing packages and managing formal document revision control
• Ability to travel 25–30%, including internationally (valid passport required)
• Experience with data center cooling equipment (CRAH, CRAC, AHU, fan walls, CDUs) or other mission-critical HVAC products
• Familiarity with hyperscale customer qualification programs and their electrical/EMC/safety requirements
• Working knowledge of BACnet/IP, Modbus TCP/RTU, and controls integration concepts; exposure to Siemens Climatix or similar DDC/PLC platforms
• Knowledge of IEC standards, CE marking, and IECEE CB Scheme for multi-market product certification; understanding of 50/60 Hz design deltas
• Familiarity with UL 60335-2-40, UL 1995, IEC 62443 cybersecurity concepts, and IEEE color book methods
• Professional Engineer (PE) license or progress toward licensure
• Experience working with global engineering teams across time zones
