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
