Senior OT / SCADA Integration & Commissioning Lead (Industrial Automation & Infrastructure Projects)
Location: London
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 who can operate between hands-on SCADA/PLC work and 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
The position sits within projects characterised by multi-vendor SCADA environments, complex OT system integration, commission-intensive phases, interaction with EPCs, OEMs and plant operators. The key challenge is ensuring systems are not only installed, but fully integrated and operational in real conditions.
Key Responsibilities
- Commissioning & Integration Lead
- Lead and execute SCADA and control systems commissioning activities.
- Validate integration between PLC systems, SCADA platforms and third-party/OEM systems.
- Ensure correct behaviour of signals and commands versus feedback system states.
- Industrial Networks & Communications (Core Capability)
- Lead and support the configuration, validation and troubleshooting of industrial communication networks.
- Hands-on work with industrial network infrastructure: configuration of managed industrial switches, IP addressing aligned with system architecture, VLAN configuration and traffic segmentation, and basic routing concepts.
- Validate and support network topologies (star, ring, redundant architectures) and distributed I/O networks; ensure separation between control, SCADA and external systems.
- 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, intermittent communication issues, misconfiguration and protocol-level problems.
- Diagnose connectivity failures, latency, physical layer issues, cabling, ports, redundancy switching, and switch misconfiguration.
- Apply structured troubleshooting: trace signals (field -> PLC -> network -> SCADA), isolate root cause (logic vs network vs configuration) and validate real vs displayed system state.
- Integration with System Behaviour
- Ensure network configuration supports reliable command execution, feedback consistency and real-time performance.
- Detect scenarios where systems appear functional but are degraded; ensure SCADA reflects real system state.
- Coordinate with OT & Infrastructure teams, network/IT/OT security vendors/integrators; align network configuration with system architecture and commissioning requirements.
- Operational Reliability & Readiness
- Validate that 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 and ensure end to end coherence of system behaviour across field devices, PLC logic, industrial network and SCADA systems.
- Ensure full alignment between PLC states, transmitted data and SCADA representation; resolve discrepancies between commanded vs actual state, logic vs visualisation, real system vs operator perception.
- Validate traceability of signals (field -> PLC -> network -> SCADA); diagnose issues by tracing signal origin, analysing transformations and validating final behaviour.
- Identify situations where SCADA shows operation but the system is not functioning; prevent misleading status, silent failures and undetected degradation.
- Integrate PLC logic, communications and SCADA into a single coherent system; own resolution of cross-discipline or vendor gaps.
- Ensure system behaviour is predictable, verifiable and aligned with reality.
- Technical Coordination
- Act as interface between EPC contractors, SCADA vendors, engineering teams and operations.
- Coordinate implementation with operational needs 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 such as PcVue, PCS7, WinCC/AVEVA; ensure proper alarms, monitoring, data coherence.
- Project Delivery Support
- Support FAT/SAT and contribute to delivery readiness.
- Mitigate risks related to integration, sequencing and dependencies.
Required Profile
- Experience
- Strong industrial automation / SCADA experience.
- Strong experience in commissioning, system integration and field environments.
- Experience in infrastructure / energy / industrial projects within 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; practical experience in switch configuration and network troubleshooting in the field.
- Systems & Delivery: commissioning integration coordination.
- Additional experience with PV plants, energy industrial retrofit infrastructure systems is a plus.
