HireIQ Solutions is leading the search for a Controls Engineer with a U.S. manufacturer of engineered-to-order HVAC equipment serving mission-critical environments, including data centers, cleanrooms, and other highly technical applications.
The company designs, manufactures, tests, and commissions custom HVAC systems where controls are central to equipment performance. This is not a traditional building automation role, and it is not a pure PLC programming role. The right candidate will bring a strong combination of HVAC equipment knowledge, controls programming capability, troubleshooting ability, and practical field-support experience.
The Controls Engineer will play a critical role in developing PLC/DDC-based controls programs for custom HVAC production orders, supporting equipment commissioning and testing, and troubleshooting controls issues on equipment that has been installed in the field. This role requires someone who can do more than write code. The ideal candidate will understand how HVAC equipment operates, how systems should perform under different operating conditions, and how to translate that knowledge into control strategies, sequences of operation, and real-world troubleshooting support. The person in this role will work closely with sales engineers, applications engineers, field service technicians, manufacturing teams, and customers to ensure equipment performs as designed.
In-House Engineering & Support
Experience programming, commissioning, and troubleshooting PLC- or DDC-based controls systems
Strong understanding of HVAC equipment operation, not just controls architecture
Ability to develop control strategies and sequences of operation for custom HVAC systems
Hands-on knowledge of mechanical systems, HVAC systems, and building automation concepts
Experience working with custom or engineered-to-order equipment is highly relevant
Familiarity with manufacturing, factory testing, commissioning, or field service environments is preferred
PLC programming experience using ladder logic, function block, structured text, or similar programming languages
Experience with DDC/PLC platforms such as Carel, Automated Logic, Distech, Johnson Controls, Trane, Alerton, Siemens, Allen-Bradley, Beckhoff, or similar systems
Knowledge of air-cooled and water-cooled chillers, air handling equipment, hydronic systems, boiler systems, and refrigerant-based controls
Experience with VFDs, ECM motors, fan control, and related components, including systems such as Ziehl-Abegg, ebm-papst, or similar technologies
Ability to specify and troubleshoot control components such as sensors, valves, actuators, power monitoring devices, and related field devices
Working knowledge of communication protocols, including MODBUS RTU/TCP, BACnet MSTP/IP, and Ethernet networking
Ability to read, interpret, and troubleshoot low-voltage and three-phase electrical systems
Experience with AutoCAD or similar design/documentation platforms is preferred
Develop sequences of operation that clearly define how HVAC equipment should operate
Prepare user manuals, O&M manuals, commissioning documentation, and test procedures
Document controls logic, system parameters, field findings, and corrective action plans
Translate complex controls and HVAC concepts into clear written documentation for internal and external stakeholders
Two or more years of relevant controls, HVAC, automation, commissioning, or field troubleshooting experience preferred
Combination of education and relevant hands-on experience will be considered
Working knowledge of HVAC system concepts, equipment, and terminology
Programming experience in at least one DDC, PLC, or controls programming environment
Training will be provided on company-specific product lines and controls platforms
Strong analytical and problem-solving skills
Effective written and verbal communication
Ability to work directly with customers, technicians, engineers, and manufacturing teams
Strong organizational skills and ability to manage multiple priorities
Comfortable working in a fast-paced, high-pressure environment
Team-oriented, practical, and hands-on approach to solving technical problems
Ability to connect controls programming decisions to actual HVAC equipment performance
Ability to lift up to 50 pounds as needed
Ability to sit or stand for extended periods of the workday
Periodic visits to manufacturing areas with seasonal temperature variation, dust, and limited chemical fume exposure
The company offers a competitive benefits package for full-time team members, including:
This is a high-impact controls role supporting complex, custom HVAC equipment in demanding environments. The company is specifically seeking someone who can bridge the gap between programming and HVAC application knowledge.
A strong candidate will be able to write and troubleshoot controls code, but also understand the operating logic behind the equipment: how chillers, air handlers, hydronic systems, motors, fans, valves, sensors, and field devices work together to deliver performance. That combination of controls capability and HVAC system understanding is central to success in this position.
