PLC Controls Engineer – HVAC / BMS
Overview
PLC Controls Engineer leading development and deployment of control systems for large-scale cooling and facility infrastructure in a hybrid project environment. Remote design and programming followed by onsite installation and commissioning in Haskell TX. Ideal for engineer who enjoys taking systems from concept through implementation, testing, and live troubleshooting in the field.
What You'll Do12
- 1Develop PLC programs using Allen-Bradley Studio 5000 on the Logix platform during the remote engineering phase
- 2Design and implement control logic for mechanical and cooling systems including AHU/ATU VAV systems chillers chilled water systems exhaust fans ventilation systems dampers valves airflow control devices
- 3Translate sequences of operation into clean maintainable documented control logic supporting reliable system performance
- 4Integrate field devices such as temperature pressure flow sensors transmitters actuators into PLC-based control systems
- 5Collaborate closely with cross-functional engineering and project teams to ensure control strategies align with overall system requirements
- 6Support installation and startup of control systems onsite in Haskell TX working in field environments alongside technicians engineers and contractors
- 7Perform I/O checkout and loop testing to verify proper wiring device operation and control system functionality
- 8Debug PLC code and perform real-time modifications during commissioning to resolve issues and fine-tune system behavior
- 9Conduct functional testing and system tuning to validate performance of HVAC and mechanical control systems
- 10Troubleshoot issues across controls instrumentation and communications networks identifying root causes and implementing corrective actions
- 11Partner with field teams and commissioning stakeholders during system bring-up to ensure smooth transition from construction to operational status
- 12Optimize system performance after initial startup by adjusting control parameters refining sequences and addressing operational concerns
