Generalmatter Controls Software Engineer designing and implementing control and automation software for test stands and production systems, including PLCs and SCADA/HMI. Responsible for defining architecture and operational reliability of mission-critical automation systems.

Responsibilities

We are seeking a Controls Software Engineer to design and implement the control and automation software stack for test stands and production systems. This role sits at the intersection of industrial automation and systems software engineering, and is responsible for building reliable, maintainable, and safety-critical control systems spanning PLCs, SCADA/HMI, and supporting high-performance software services. The successful candidate will play a central role in defining the architecture, implementation standards, and operational reliability of mission-critical automation systems.
Design, implement, and maintain PLC-based control systems for chemical processing equipment, test stands, and production systems.
Develop and integrate SCADA/HMI systems for monitoring, control, alarming, and operational visibility.
Build supporting services and control infrastructure for high-reliability and performance-critical components.
Define and champion modern software engineering practices, control system architecture, coding standards, testing strategies, and operational best practices across the automation stack.
Migrate and modernize existing PLC logic onto the in-house control software platform.
Work closely with hardware, electrical, and process engineering teams to integrate sensors, actuators, and field devices.
Lead debugging, root cause analysis, and reliability improvements across the full automation stack.
