[Hiring] PLC/SCADA Controls Engineer @Carrier

Role Description

ALC's work increasingly sits at the intersection of OT controls, SCADA, and enterprise data. We deploy Ignition SCADA, Rockwell Automation PLCs, and open industrial protocols to provide deep, trustworthy visibility into mechanical plants, electrical distribution, and power quality without locking customers into brittle or opaque architectures. We are seeking a senior-level PLC/SCADA Engineer who brings strong technical judgment, systems thinking, and the ability to design solutions that keep working years after handoff.

As a Senior PLC/SCADA Controls Engineer, you will serve as a technical authority for data center automation and electrical power monitoring systems. You will lead the design of Ignition-based data center SCADA platforms integrated with Rockwell PLC control systems, electrical power monitoring devices, and third-party subsystems. You will influence how systems are designed, modeled, how data flows, and how operators interact with critical infrastructure across single sites and multi-site portfolios. This role carries technical ownership, cross-disciplinary influence, and mentorship expectations.
