Job Description: Senior OT / SCADA Integration & Commissioning Lead (Industrial Automation & Infrastructure Projects)

• 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

• 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

• 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
• 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

• REQUIRED PROFILE

Experience

• Strong industrial automation / SCADA experience
• Strong experience in: commissioning, system integration, field environments
• Experience in: infrastructure / energy / industrial projects, EPC environments

Technical Background

SCADA: PcVue, PCS7, WinCC, AVEVA

PLC: Siemens (TIA Portal preferred), Schneider, Codesys

Communications & Networks

Profinet

Modbus

OPC UA industrial networks

Practical experience in: switch configuration, network troubleshooting in field

Systems & Delivery commissioning integration coordination
