This isn't HVAC or BMS work.
It's PLC-based machine control for large-scale, oil-free centrifugal chillers used in data centres, industrial facilities and critical infrastructure worldwide.
If you enjoy Structured Text, safety-critical logic and product engineering done properly, this role will make sense very quickly.
You'll join a small, focused controls team developing control software for high-power rotating equipment where performance, protection logic and system stability genuinely matter. This is lab-based product engineering, not site firefighting.
WHY THIS ROLE IS DIFFERENT
* Work on industrial machines, not building automation
* Controls software for high-value equipment where failures aren't an option
* Small, capable team where your work directly impacts a global product
* Structured engineering environment with ISO9001 practices, testing and controlled releases
* Collaboration with international engineering teams across multiple regions
* Clear exposure to deeper controls, embedded systems and platform architecture
WHAT YOU'LL DO
* Develop and test PLC control software using Structured Text (IEC
* Design and maintain state machines, sequencing logic, control loops and safety interlocks
* Work on protection logic, system behaviour and stability under real operating conditions
* Lab-based commissioning, validation and troubleshooting
* Support disciplined documentation and version control processes
* Collaborate with global engineering teams on platform evolution
* Occasional domestic or international project travel (planned, not constant)
WHAT YOU'LL NEED
* 2–3 years' experience in PLC controls or industrial automation
* Strong Structured Text fundamentals and FBD (ladder-only backgrounds won't suit)
* Experience with complex machine control and safety-critical systems
* Background in Siemens, Rockwell/Allen-Bradley, Schneider or similar PLC platforms
* Comfortable working in a structured, quality-driven engineering environment
* Clear communicator with a methodical approach to problem-solving
NICE TO HAVE
* Exposure to C#, Python or Java (tools, diagnostics, IPC-based logic)
* Beckhoff (TwinCAT), CODESYS or other soft PLC / IPC-based control environments
* Experience with Modbus, BACnet, CAN or similar protocols
* Background in machinery, OEMs, manufacturing, process control, F&B, pharma or water
If you want controls engineering where performance, safety and quality genuinely matter, not endless maintenance tickets or building automation — let's talk.
