We’re looking for practical, hands‑on engineers with a foundation in PLCs who are ready to take the next step in their automation career. Whether your background is in installation, maintenance, software, or SCADA, if you understand control systems and want to get involved in full automation project delivery, we’d like to hear from you.

In this role, you’ll support projects from initial design through to on‑site commissioning, working on systems that support critical UK infrastructure – particularly in the water, utilities, and energy sectors.

It’s a great opportunity for someone who’s technically capable and eager to broaden their skills across PLCs, SCADA, and real‑world automation delivery. We offer a supportive team environment where you can grow, take on more responsibility, and progress your career in industrial automation.

• Design and develop PLC software based on Functional Design Specifications (FDS), derived from the client’s control philosophy or User Requirement Specification (URS). Carry out simulations and testing throughout the project lifecycle, including iFAT, cFAT, and SAT
• Contribute to the setup, configuration, and validation of industrial networks. Develop and modify SCADA and HMI applications using industry‑standard platforms
• Provide on‑site and remote commissioning support, including I/O checks and system validation, and diagnose and resolve control system issues during commissioning and post‑installation callouts
• Collaborate effectively with engineers, electricians, and client stakeholders to deliver integrated solutions
• Ensure all software, documentation, and testing procedures comply with Quality Management System (QMS) and client requirements

• Siemens TIA Portal – including Step 7 (S7-1200/S7-1500) and legacy support for S7-300/400
• Mitsubishi GX Works2, GX Works3, or GX Developer – used for programming FX, Q, and iQ‑R series PLCs
• Schneider Electric Eco Struxure Control Expert (formerly known as Unity Pro) – used for Modicon M340, M580, and Premium PLCs
• Rockwell Automation Studio 5000 (formerly RSLogix 5000) – for Control Logix and Compact Logix PLCs

• Experience with SCADA platforms such as WinCC, iFIX, VTScada, ClearSCADA, InTouch, Citect, or Ignition
• Motor control systems including VSDs, soft starters, intelligent overloads, and relay/contactor logic
• OT networking:
  Ethernet protocols (TCP/IP, UDP), industrial protocols (Modbus, Profibus, Profinet), VLANs, fibre optic networks, network redundancy (e.g. MRP, RSTP), and basic routing, plus awareness of cybersecurity standards such as IEC 62443
• Process control knowledge, including PID tuning, loop optimisation, and control sequencing
• Strong electrical competence – fault finding, I/O testing, and panel wiring (digital and analogue), with experience commissioning automation software on‑site, including I/O validation, system testing, and live fault resolution
• Familiarity with UK water industry telemetry systems, including Servelec S250, S500, and S2000 outstations, DNP3 communication protocols, and cellular modem integration
• Industry background in water, utilities, energy, or manufacturing environments
• HNC/HND in Electrical, Mechanical, Automation, or a related engineering discipline (or equivalent experience), and/or an ECS or CSCS card
• Willingness to travel within the…
