Senior OT​/SCADA Integration & Commissioning Lead

Position: Senior OT / SCADA Integration & Commissioning Lead
Location: Greater London

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.

Based:
London based

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

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)
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

Align implementation with operational needs

Coordinate during: startup, shutdown, commissioning

3.5 System Validation & Troubleshooting

Identify and resolve integration issues across: communications, SCADA-PLC interaction, instrumentation

Validate full system behaviour under real conditions

SCADA & OT Systems

Support SCADA platforms:
PcVue, PCS7, WinCC / AVEVA

Ensure: proper alarms, monitoring, data coherence

3.7 Project Delivery Support

Support FAT/SAT

Contribute to delivery readiness

Mitigate risks related to:
Integration, sequencing, dependencies

4. REQUIRED PROFILE Experience

• Strong industrial automation / SCADA experience
• Strong experience in: commissioning, system integration, field…
