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 evolved into coordination, capable of operating between:

• hands-on SCADA / PLC work
• 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. Location: London 2.

Role Context

The position sits within projects characterised by:

• multi-vendor SCADA environments
• complex OT system integration
• commissioning-intensive phases
• interaction with EPCs, OEMs and plant operators Key challenge: ensuring systems are not only installed, but fully integrated and operational in real conditions Based: London based 3.

Key Responsibilities

3.1 Commissioning & Integration

• Lead and execute SCADA and control systems commissioning activities
• Validate integration between:
• PLC systems
• SCADA platforms
• third-party/OEM systems
• Ensure correct behaviour of:
• signals
• commands vs feedback
• system states 3.2 Industrial Networks & Communications ( Core Capability )
• Lead and support the configuration, validation and troubleshooting of industrial communication networks as a core part of system integration and commissioning. Network Configuration & Infrastructure
• Work hands-on with industrial network infrastructure, including:
• configuration of managed industrial switches
• IP addressing aligned with system architecture
• VLAN configuration and traffic segmentation
• basic routing concepts (subnets, gateways, inter-network communication)
• Support and validate network topologies:
• star / ring / redundant architectures
• distributed I/O networks
• separation between control, SCADA and external systems Industrial Protocols & Data Flow

• Diagnose issues such as:
• connectivity failures
• latency / instability
• physical layer issues (cabling, ports, redundancy switching)
• switch misconfiguration
• Apply structured troubleshooting:
• trace signals (field → PLC → network → SCADA)
• isolate root cause (logic vs network vs configuration)
• validate real vs displayed system state Integration with System Behaviour
• Ensure network configuration supports:
• reliable command execution
• feedback consistency
• real-time performance
• Detect scenarios where:
• systems appear functional but are degraded
• SCADA does not reflect real system state Coordination with OT & Infrastructure Teams
• Interface with:
• network / IT / OT security
• vendors / integrators
• Align:
• network configuration
• system architecture
• commissioning requirements Operational Reliability & Readiness
• Validate that networks are: stable, properly structured, aligned with system criticality

• Own and ensure end-to-end coherence of system behaviour across: field devices, PLC logic, industrial network, SCADA systems Single Source of Truth
• Ensure full alignment between: PLC states, transmitted data, SCADA representation
• Resolve discrepancies between: commanded vs actual state, logic vs visualisation, real system vs operator perception End-to-End Traceability
• Validate traceability of signals: field → PLC → network → SCADA
• Diagnose issues by: tracing signal origin, analysing transformations, validating final behaviour False State Detection
• Identify situations where:
• SCADA shows operation but system is not functioning
