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 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 environments

Experience in: infrastructure / energy / industrial projects, EPC environments

Real commissioning experience

System-level troubleshooting capability

Ability to detect cross-layer inconsistencies (PLC–Network–SCADA)

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

Additional

PV plants / energy

industrial retrofit

infrastructure systems
