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

• 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
