About The Position

Carrier Global Corporation, a global leader in intelligent climate and energy solutions, is committed to creating innovations that bring comfort, safety, and sustainability to life. Through cutting-edge advancements in climate solutions such as temperature control, air quality, and transportation, we improve lives, empower critical industries, and ensure the safe transport of food, lifesaving medicines, and more. Since inventing modern air conditioning in 1902, we lead with purpose: enhancing the lives we live and the world we share. We continue to lead because of our world-class, inclusive workforce that puts the customer at the center of everything we do. Automated Logic has been developing and supporting intelligent building solutions for over 40 years, helping customers operate their buildings more efficiently. Our products reduce energy consumption, lower utility, operating, and maintenance costs, and improve indoor air quality, occupant comfort, and productivity. This role sits at the intersection of OT controls, SCADA, and enterprise data, deploying Ignition SCADA, Rockwell Automation PLCs, and open industrial protocols to provide visibility into mechanical plants, electrical distribution, and power quality. We are seeking lead-level PLC/SCADA Engineers with strong technical judgment, systems thinking, and the ability to design solutions that are maintainable long-term. As a Lead PLC/SCADA Engineer, you will be a technical authority for data center automation and electrical power monitoring systems, leading the design of Ignition-based SCADA platforms integrated with Rockwell PLC control systems, electrical power monitoring devices, and third-party subsystems. You will influence system modeling, data flow, and operator interaction with critical infrastructure across single sites and multi-site portfolios. This role involves technical ownership, cross-disciplinary influence, and mentorship.
