Seven Executive Limited; United States; On-site; USD 110,000 - 140,000; Full time

Job summary

Seven Executive Limited is seeking a Senior Electrical Engineer to own the electrical design of data center cooling equipment from concept to production release and field commissioning, emphasizing UL 508A compliant control panels and EPLAN/AutoCAD Electrical.

You will convert outsourced drawing packages into in-house standard designs across CRAH, AHU, FCU/FCW, CDU, and collaborate with manufacturing, suppliers, and customers worldwide. Travel ~20%.

Qualifications

• Bachelor's degree in Electrical Engineering or a closely related discipline.
• 8+ years of electrical design experience in industrial equipment, HVAC/mechanical equipment, control panels, mission-critical infrastructure, or a closely related environment.
• Expert-level EPLAN Electric P8 experience, including project structuring, macro development, article management, and cross-referencing.
• Strong working knowledge of AutoCAD Electrical.
• Demonstrated ownership of UL 508A control panel designs, including SCCR calculations in accordance with Supplement SB.
• UL 508A MTR certification, or the ability to obtain certification within six months.
• Strong command of NEC/NFPA 70, particularly Articles 310, 409, 430, and 440.
• Ability to independently perform and document FLA/MCA/MOP, voltage drop, conductor sizing, protection coordination, transformer sizing, and panel heat-load calculations.
• Hands-on experience with VFDs, EC motors, three-phase power distribution, control transformers, and 24V control architectures.
• Experience producing complete, production-ready electrical drawing packages.
• Experience with formal engineering documentation and revision control processes.
• Willingness and ability to travel approximately 25–30% including internationally.

Responsibilities

• Develop complete electrical schematic packages covering 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 colour coding, and nameplate/marking requirements.
• Build and maintain EPLAN master data including symbol libraries, macros, article/parts databases, project templates, and title block standards.
• Design power circuits for EC fan arrays, VFD-driven pumps and fans, 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 controllers, I/O extension modules, HMIs, sensors, safety relays, and BACnet/Modbus network segments.
• Design hardwired safety chains including HOA, E-stop, smoke detection, leak detection, and external interlocks using fail-safe, normally-closed architecture.
• Perform Full Load Amps (FLA) and Minimum Circuit Ampacity (MCA) / Maximum Overcurrent Protection (MOP) calculations.
• Determine Short-Circuit Current Rating (SCCR) for control panels.
• Complete conductor and cable sizing, ampacity derating, and voltage drop calculations.
• Select and coordinate fuses and circuit breakers, motor branch-circuit protection, and transformer primary/secondary protection.
• Complete transformer and control power supply sizing, including inrush, regulation, and load-growth margin.
• Perform panel heat-load and thermal-dissipation calculations and determine enclosure thermal management requirements.
• Verify motor and VFD sizing, harmonic considerations, and 50 Hz versus 60 Hz design requirements.
• Support grounding and bonding design, wire-pull and conduit-fill calculations, and arc-flash awareness activities.
• Own assigned electrical standards within the controlled document register and author, revise, and release standards through formal engineering review processes.
• Classify electrical design elements as Fixed, Configurable, or Project-Specific (F/C/P) and enforce the classification throughout project execution.
• Convert legacy outsourced drawing packages into controlled, in-house EPLAN standard packages.
• Conduct gap analyses between existing drawings, product requirements, BOMs, and customer specifications.
• Develop and maintain standard BOMs using approved component libraries and approved alternates.
• Track component lifecycle and obsolescence requirements.
• Support engineering collaboration across North American and international engineering teams.
• Assist with drawing-standard alignment, EPLAN workflows, and re-certification requirements for products manufactured to different international standards.
