Senior OT / SCADA Integration & Commissioning Lead in City of Westminster

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.

ROLE CONTEXT

• 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.

Commissioning & Integration Lead

• Validate integration between PLC systems, SCADA platforms, third‑party/OEM systems.
• Ensure correct behaviour of signals, commands vs feedback system states.

Industrial Networks & Communications (Core Capability)

• Lead and support configuration, validation and troubleshooting of industrial communication networks, including managed industrial switches and VLAN configuration.
• Configure IP addressing, routing, subnets and gateways aligned with system architecture.
• Support and validate network topologies: star, ring, redundant architectures and distributed I/O networks.
• Ensure correct configuration and operation of Profinet, Modbus TCP, OPC UA.
• Validate end‑to‑end data flow across field devices, PLCs and SCADA systems; identify and resolve data inconsistencies or stale values.
• Diagnose connectivity failures, latency, physical layer issues, and apply structured troubleshooting to isolate root cause.

Integration with System Behaviour

• Ensure network configuration supports reliable command execution and feedback consistency.
• 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 and align network configuration with system architecture and commissioning requirements.

Operational Reliability & Readiness

• Validate networks are stable, properly structured and aligned with system criticality.
• Ensure readiness for FAT/SAT, commissioning and handover.

System Coherence & Cross‑Layer Ownership (PLC, Network, SCADA)

• Own end‑to‑end coherence of field devices, PLC logic, industrial network and SCADA systems.
• Resolve discrepancies between commanded vs actual state, logic vs visualisation, real system vs operator perception.
• Validate traceability of signals and detect false state situations.

Resolution Ownership

• Resolve issues across PLC, network and SCADA, avoiding gaps between disciplines or vendors.

Operational Trust

• Ensure system behaviour is predictable, verifiable and aligned with reality.

Technical Coordination

• Act as interface between EPC contractors, SCADA vendors, engineering teams and operations.
• Align implementation with operational needs and coordinate during startup, shutdown and commissioning.

System Validation & Troubleshooting

• Identify and resolve integration issues across communications, SCADA‑PLC interaction and instrumentation.
• Validate full system behaviour under real conditions.
• Support SCADA platforms: PcVue, PCS7, WinCC/AVEVA; ensure alarms, monitoring and data coherence.

Project Delivery Support

• Support FAT/SAT and contribute to delivery readiness.
• Mitigate risks related to integration, sequencing and dependencies.

Qualifications & Experience

• Strong industrial automation / SCADA experience.
• Strong experience in commissioning, system integration and field environments.
• Experience in infrastructure / energy / industrial projects, EPC environments.
• Real commissioning experience and system‑level troubleshooting capability.
• Ability to detect cross‑layer inconsistencies (PLC, Network, SCADA).
• Technical background in SCADA (PcVue, PCS7, WinCC, AVEVA), PLC (Siemens TIA Portal preferred, Schneider, Codesys).
• Communications & networks knowledge of Profinet, Modbus, OPC UA and industrial networks.
• Practical experience in switch configuration, network troubleshooting in field.
• Experience with PV plants / energy projects.
