Senior OT​/SCADA Integration & Commissioning Lead

Position: Senior OT / SCADA Integration & Commissioning Lead
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)
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…
