Supporting Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and commissioning activities.
Maintaining clear technical documentation, version control, and configuration backups.
Diagnosing and resolving issues in both simulated and live environments — locally and remotely.
Working closely with engineering and controls colleagues to deliver best-in-class monitoring and automation solutions.

Experience

Essential:

2+ years’ experience with CODESYS or similar PLC platforms (Siemens TIA Portal, Beckhoff TwinCAT, ABB).
Strong understanding of Structured Text (ST) and other IEC 61131-3 languages.
Background in industrial automation or energy control systems.
Ability to interpret electrical schematics and P&IDs.
Experienced in testing, debugging, and troubleshooting real-time control systems.
Knowledge of control system design principles (signal conditioning, interlocks, safety systems).

Desirable:

Experience with BESS, HVAC controls, or renewable/energy systems.
Knowledge of industrial networking, firewalls, routers, and communication protocols.
Exposure to HMI/visualisation tools (CODESYS Visualisation, Ignition, Wonderware).
Experience with Linux-based embedded systems or RTOS.
