Software​/PLC Programmer

As the software/PLC Programmer you will be responsible for developing and maintaining high-quality PLC-based control and monitoring software to support industrial and energy systems. The role ensures programmed solutions are reliable, safe and delivered inline with technical specifications, engineering standards, and customer requirements. Working closely with the engineering and control team, you will support the full life cycle of control systems, including design, testing, commissioning and operational troubleshooting whilst maintaining robust documentation and configuration control.

• Design, develop, enhance, and test PLC-based control applications using CODESYS (IEC languages: ST, FBD, SFC, LD).
• Implement and debug logic for real-time systems, control panels, and industrial automation networks.
• Translate functional specifications into detailed, maintainable, and scalable program logic with an emphasis on safety.
• Integrate third‑party hardware and protocols (e.g., Modbus TCP/RTU, CANopen, OPC UA, Ethernet/IP).
• Support Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and commissioning activities as required.
• Maintain accurate technical documentation, version control, and configuration backups in accordance with internal quality processes.
• Diagnose and resolve issues in live environments, supporting both local and remote troubleshooting.
• Collaborate with the wider team to deliver best‑in‑class monitoring solutions.

• Appropriate Engineering qualification
• Essential:
  • 2+ years' experience with CODESYS or similar platforms (e.g., Siemens TIA Portal, Beckhoff TwinCAT, WAGO e!
    
    COCKPIT).
  • Strong knowledge of IEC programming languages, especially Structured Text (ST).
  • Proven experience developing logic for industrial automation or energy control systems.
  • Familiarity with control system design principles (signal conditioning, interlocks, safety systems).
  • Ability to read and interpret electrical schematics and P&IDs.
  • Skilled in testing and debugging both simulated and live systems.
• Desirable:
  • Experience with BESS, HVAC controls, or renewable energy systems.
  • Knowledge of networking, routers, firewalls, and industrial communication protocols.
  • Exposure to visualization/HMI platforms (e.g., CODESYS Visualization, Ignition, Wonderware).
  • Experience with Linux-based embedded systems or RTOS.
  • Hands‑on experience with WAGO PLCs and edge computers.
  • Knowledge of cloud computing and visualisation tools (e.g., Grafana).
• Please apply for immediate consideration
