About the role

Key responsibilities & impact

Engineer the virtualized PLC platform: control logic moving from proprietary boxes to software-defined infrastructure.
Port and validate control applications onto virtual runtimes without giving up determinism or safety.
Build the test harnesses that prove virtual controls against hardware behavior before a site sees them.
Define the reference architecture: networking, redundancy, and failover for controls as software.

Requirements

What you’ll need

You've programmed industrial controls professionally: PLC platforms and IEC 61131 languages.
You've worked with virtualization or software-based control runtimes.
You test control logic like lives depend on it, because they can.
You understand determinism, scan times, and what breaks when controls become software.
You document control narratives engineers and operators both use.
Bonus: Codesys or software PLCs. Hypervisors and real-time Linux. BMS and EPMS applications. Functional safety.
