Control Systems Engineer (PLC / SCADA / MES)

Location: Reading

Employment Type: Full‐time

Department: Automation & Manufacturing Systems

Role Overview

You’ll be the technical lead for designing, developing, and supporting industrial control systems across PLC, SCADA, and MES platforms. This role sits at the intersection of automation engineering and manufacturing IT, ensuring reliable, safe, and optimised operation of production assets. You’ll work closely with operations, maintenance, and IT teams to deliver robust automation solutions and continuous improvements across the site.

Key Responsibilities

• PLC Programming & Integration — Develop, modify, and troubleshoot PLC logic (Siemens, Allen‐Bradley, Mitsubishi, or similar) for new equipment, upgrades, and process optimisation.
• SCADA/HMI Development — Design and maintain SCADA and HMI systems (e.g., WinCC, FactoryTalk View, Ignition) including graphics, alarms, historian configuration, and user workflows.
• MES Implementation & Support — Configure and support MES modules such as production tracking, recipe management, OEE, traceability, and data exchange with ERP systems.
• System Architecture & Design — Produce functional design specs, control philosophies, network diagrams, and documentation for automation projects.
• Commissioning & Testing — Lead FAT/SAT, commissioning, and validation activities for new automation systems and upgrades.
• Troubleshooting & Root Cause Analysis — Provide expert-level support for control system faults, downtime events, and process deviations.
• Cybersecurity & Compliance — Ensure systems meet site standards for safety, cybersecurity, and regulatory compliance (e.g., IEC 61131‐3, ISA‐95, GAMP).
• Continuous Improvement — Identify automation opportunities to improve throughput, quality, and reliability.
• Cross‐functional Collaboration — Work with production, maintenance, quality, and IT teams to deliver integrated solutions.

Required Skills & Experience

• Degree or HNC/HND in Electrical Engineering, Control & Automation, Mechatronics, or related discipline.
• Strong experience with PLC programming (Siemens TIA Portal, Rockwell Studio 5000, or equivalent).
• Hands‐on experience developing and supporting SCADA/HMI systems.
• Working knowledge of MES platforms (e.g., Siemens Opcenter, Rockwell FT MES, Wonderware MES).
• Solid understanding of industrial communication protocols (EtherNet/IP, Profinet, Modbus TCP, OPC UA).
