HVAC Controls Engineer: UL 508A, PLC & Panel Design

Exemplar Global; Baton Rouge (LA); On-site; USD 85,000 - 120,000; Full time

Job summary

Exemplar Global in Baton Rouge, LA is seeking an Electrical Engineer experienced in designing and commissioning industrial control panels and PLC programming for HVAC applications. You will design UL 508A panels, develop electrical schematics, and support certification processes.

The role involves hands-on wiring, debugging, and collaborating with engineering and production to translate system requirements into robust control solutions, including exposure to explosion-proof/hazardous-location

Qualifications

• Hands-on experience designing UL 508A control panels from scratch.
• Strong fundamentals in electrical control design (relay logic, motor controls, power distribution).
• Experience with industrial/HVAC controller platforms (Allen-Bradley, Siemens, Carel, Honeywell/Johnson Controls, Danfoss, Emerson).
• Proficiency in ladder logic, structured text, or function block programming; C/C++ a plus.
• Ability to read and create electrical schematics independently.
• Familiarity with NEC 500-505 and UL 508A standards.
• EPLAN or comparable electrical CAD experience a plus.
• Industrial, HVAC/refrigeration, or hazardous-location experience a plus.
• BS in Electrical Engineering or equivalent hands‑on experience.

Responsibilities

• Design UL 508A control panels from scratch: enclosure selection, component selection (breakers, contactors, relays, terminal blocks, power supplies), and internal layout
• Develop electrical schematics and panel drawings (EPLAN experience a plus — we're rolling it out)
• Program and configure PLCs and HMIs for custom HVAC/refrigeration equipment (Allen-Bradley, Siemens, Carel, Honeywell/Johnson Controls, Danfoss, or Emerson platforms)
• Write and troubleshoot control logic in ladder logic, structured text, function block diagram, and/or C/C++
• Partner with engineering and production to translate system requirements into control solutions
• Support controls integration for explosion-proof/hazardous-location equipment (NFPA 496, Class I/II Div 1 & 2 a plus)
• Troubleshoot panels and wiring during build, test, and commissioning
• Maintain BOMs and support UL field-labeling/certification
