  • Pumps and HVAC equipment

• Review ladder logic, function blocks, and interlocks to isolate root cause

• Coordinate with operations and maintenance teams to implement corrective actions

• Support system modifications and minor logic adjustments when required

• Verify communications between PLCs, HMIs, BMS, and EPMS systems

• Maintain system documentation and ensure changes follow MOC (Management of Change) procedures

• Participate in incident response for uptime-critical systems

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Mechatronics, or related engineering discipline

• 3+ years of experience working with Allen-Bradley PLC systems

• Hands-on experience navigating and troubleshooting in Studio 5000

• Strong understanding of ladder logic and industrial control architecture

• Experience with EtherNet/IP and industrial communication protocols

• Ability to analyze electrical schematics and P&IDs

Preferred Qualifications

• Experience in data center, power generation, manufacturing, or other mission-critical facilities

• Familiarity with EPMS and BMS system integration
