Job Description:

• Senior OT / SCADA Integration & Commissioning Lead
• (Industrial Automation & Infrastructure Projects)

1. 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

• •Ensure correct configuration and operation of: Profinet, Modbus TCP, OPC UA
• •Validate end-to-end data flow across: field devices, PLCs, SCADA systems
• •Identify and resolve:
• •data inconsistencies or stale values
• •intermittent communication
• •addressing/configuration mismatch
• •protocol-level issues

Network Diagnostics & Troubleshooting

• •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
• •Ensure readiness for: FAT / SAT, commissioning, 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, 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
• •feedback does not reflect real status
• •communication creates false truths

Ensure system avoids: misleading status, silent failures, undetected degradation

Cross-Domain Integration

Ensure that: PLC logic, communications, SCADA operate as a single coherent system.

Resolution Ownership

Take responsibility for resolving issues across: PLC, network, SCADA avoiding gaps between disciplines or vendors

Operational Trust

Ensure system behaviour is: predictable, verifiable, aligned with reality

3.4 Technical Coordination

• •Act as interface between: EPC contractors, SCADA vendors, engineering teams, operations
