hirify.global develops next-generation fusion-energy technology and related R&D and processing equipment.

What you will do

• Design complete electrical architectures for complex R&D tools, including 480VAC power distribution, low-voltage DC systems, cable harnesses, power conditioning, and control-reliable safety systems.
• Create, modify, and approve AutoCAD Electrical schematic packages, panel layouts, I/O diagrams, terminal blocks, cable schedules, and wire-harness documentation in accordance with NFPA 79, NEC, and UL 508A.
• Integrate power supplies, circuit protection, VFDs, servo drives, safety relays, thermocouples, pressure transducers, vacuum gauges, and flow meters.
• Design grounding, shielding, and isolation solutions for signal integrity and EMI/EMC mitigation in high-power, high-magnetic-field environments.
• Lead shop-floor electrical testing, ring-out, power-up, I/O checkout, commissioning, troubleshooting, and electrical fault isolation.
• Support controls integration, external panel shops, electrical contractors, component BOMs, and Factory Acceptance Testing.

Requirements

• Bachelor’s degree in Electrical Engineering or Mechatronics Engineering is required; a master’s degree is preferred.
• 8+ years of dedicated electrical engineering experience designing power distribution, electrical cabinets, and hardware architectures for complex industrial or R&D capital equipment.
• Expert proficiency with AutoCAD Electrical for schematic generation, panel layouts, terminal-block design, and wire-harness documentation.
• Deep understanding of 480VAC three-phase systems, transformer sizing, short-circuit current ratings, arc-flash safety, NFPA 79, NEC/NFPA 70, and UL 508A.
• Experience solving EMI/EMC, noise-coupling, grounding, and signal-integrity challenges in complex electromechanical tools.
• Working knowledge of PLC architectures such as Beckhoff, Allen-Bradley, or Siemens; EtherCAT or EtherNet/IP; and safety PLCs including TwinSAFE.
• High proficiency in hands-on hardware troubleshooting, field wiring, commissioning, and electrical fault isolation on the machine floor.
• Ability to lift up to 25 lbs occasionally and perform stooping, climbing, standing, and extended sitting.
• Willingness to travel or occasionally work nights, weekends, or on-call shifts; commitment to working safely around heat, cold, noise, fumes, strong magnets, lead, high voltage, high current, pressure systems, and cryogenics.

Nice to have

• Experience with semiconductor tools, high-vacuum systems, or high-temperature processing equipment.
• Experience with high-current DC power supplies, magnetics, or cryogenic instrumentation.
• Ability to write and debug IEC 61131-3 Structured Text or Python scripts for hardware testbeds.
• Exposure to Inductive Automation Ignition or custom operational interfaces.
