Edgcote, Oxfordshire
Senior OT / SCADA Integration & Commissioning Lead (Industrial Automation & Infrastructure Projects) Location: London Role Purpose We are seeking a Senior OT / SCADA Integration & Commissioning Lead to support the delivery of complex industrial and infrastructure projects, with a focus on system integration, commissioning and technical coordination in field environments. The role is designed for a senior technical professional who can operate between hands-on SCADA/PLC work and system-level integration coordination of EPC contractors, vendors and operations. This is not a pure Project Manager role, but a technical delivery and integration role. Role Context The position sits within projects characterised by multi-vendor SCADA environments, complex OT system integration, commission-intensive phases, interaction with EPCs, OEMs and plant operators. The key challenge is ensuring systems are not only installed, but fully integrated and operational in real conditions. Key Responsibilities Commissioning & Integration Lead Lead and execute SCADA and control systems commissioning activities. Validate integration between PLC systems, SCADA platforms and third-party/OEM systems. Ensure correct behaviour of signals and commands versus feedback system states. Industrial Networks & Communications (Core Capability) Lead and support the configuration, validation and troubleshooting of industrial communication networks. Hands-on work with industrial network infrastructure: configuration of managed industrial switches, IP addressing aligned with system architecture, VLAN configuration and traffic segmentation, and basic routing concepts. Validate and support network topologies (star, ring, redundant architectures) and distributed I/O networks; ensure separation between control, SCADA and external systems. Ensure correct configuration and operation of Profinet, Modbus TCP, OPC UA; validate end to end data flow across field devices, PLCs and SCADA systems. Identify and resolve data inconsistencies or stale values, intermittent communication issues, misconfiguration and protocol-level problems. Diagnose connectivity failures, latency, physical layer issues, cabling, ports, redundancy switching, and switch misconfiguration. Apply structured troubleshooting: trace signals (field -> PLC -> network -> SCADA), isolate root cause (logic vs network vs configuration) and validate real vs displayed system state. Integration with System Behaviour Ensure network configuration supports reliable command execution, feedback consistency and real-time performance. Detect scenarios where systems appear functional but are degraded; ensure SCADA reflects real system state. Coordinate with OT & Infrastructure teams, network/IT/OT security vendors/integrators; align network configuration with system architecture and commissioning requirements. Operational Reliability & Readiness Validate that networks are stable, properly structured and aligned with system criticality. Ensure readiness for FAT/SAT, commissioning and handover. System Coherence & Cross-Layer Ownership (PLC - Network - SCADA) Own and ensure end to end coherence of system behaviour across field devices, PLC logic, industrial network and SCADA systems. Ensure full alignment between PLC states, transmitted data and SCADA representation; resolve discrepancies between commanded vs actual state, logic vs visualisation, real system vs operator perception. Validate traceability of signals (field -> PLC -> network -> SCADA); diagnose issues by tracing signal origin, analysing transformations and validating final behaviour. Identify situations where SCADA shows operation but the system is not functioning; prevent misleading status, silent failures and undetected degradation. Integrate PLC logic, communications and SCADA into a single coherent system; own resolution of cross-discipline or vendor gaps. Ensure system behaviour is predictable, verifiable and aligned with reality. Technical Coordination Act as interface between EPC contractors, SCADA vendors, engineering teams and operations. Coordinate implementation with operational needs during startup, shutdown and commissioning. System Validation & Troubleshooting Identify and resolve integration issues across communications, SCADA-PLC interaction and instrumentation. Validate full system behaviour under real conditions; support SCADA platforms such as PcVue, PCS7, WinCC/AVEVA; ensure proper alarms, monitoring, data coherence. Project Delivery Support Support FAT/SAT and contribute to delivery readiness. Mitigate risks related to integration, sequencing and dependencies. Required Profile Experience Strong industrial automation / SCADA experience. Strong experience in commissioning, system integration and field environments. Experience in infrastructure / energy / industrial projects within EPC environments. Real commissioning experience; system level troubleshooting capability. Ability to detect cross-layer inconsistencies (PLC-network-SCADA). Technical Background SCADA: PcVue, PCS7, WinCC, AVEVA. PLC: Siemens (TIA Portal preferred), Schneider, Codesys. Communications & Networks: Profinet, Modbus, OPC UA; practical experience in switch configuration and network troubleshooting in the field. Systems & Delivery: commissioning integration coordination. Additional experience with PV plants, energy industrial retrofit infrastructure systems is a plus. Please note that this job description does not represent a comprehensive list of activities and employees may be requested to undertake other reasonable duties.
