About Automated Logic

At Automated Logic, we've been developing and supporting intelligent building solutions that have helped customers, including small businesses to Fortune 500 corporations, operate their buildings more efficiently for over 40 years. Our products help reduce energy consumption, lower utility, operating and maintenance costs, and improve indoor air quality, occupant comfort, and productivity. Technology that supports the buildings and industry of today and tomorrow requires a wide range of talents and skill sets.


About This Role

Our 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 senior-level PLC/SCADA Engineer who brings strong technical judgment, systems thinking, and the ability to design solutions that keep working years after handoff.


Scope of Position:


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. You are someone others come to when the system behavior matters, not just whether it "works."
