• Interpreting, developing and capturing customer requirements.
• Designing, developing and testing PLC control system solutions.
• Producing high‑quality technical documentation aligned with customer and company standards.
• Managing data communications with third‑party equipment.
• Developing PLC software using block diagrams, flowcharts or pseudo code.
• Validating designs through analysis, testing and reviews.
• Contributing to project meetings, proposals and contract changes.

What we’re looking for:

• Experience designing and integrating large‑scale PLC control systems using Siemens products (e.g. Step 7 Classic, TIA Portal).
• Knowledge of fault‑tolerant, high‑availability and safety‑integrated PLC solutions.
• Understanding of industrial networking protocols such as Profibus, Profinet, EtherNet/IP, ModBus, TCP/IP, UDP or ASCII.
• Experience producing technical documentation.
• SCADA/PLC interfacing and driver configuration experience.
• Understanding of software development lifecycles, testing and commissioning.
• Degree/HNC/HND in Electrical/Electronic Engineering or related discipline.
• Experience within Defence, Maritime, Aerospace or regulated industries (Oil & Gas, Pharma, Petrochemical).
