OT & Telemetry Specialist

Role : OT & Telemetry Specialist The Role The OT & Telemetry Specialist is the programme's primary technical authority on outstation communications, telemetry systems, and SCADA integration. The role leads the estate assessment in Stage 1 and provides hands-on technical input through all Feasibility workstreams in Stage 2. The successful candidate must be capable of engaging credibly with an active operational technology environment from day one and working alongside utility SCADA and telemetry engineering teams throughout the programme. Your responsibilities:

• Act as the programme's technical authority for OT telemetry communications and SCADA integration across discovery and feasibility phases.
• Lead desktop-based assessment to produce a verified OT & Telemetry Asset Register using asset, GIS, and SCADA data.
• Map end-to-end telemetry communication paths, including primary, secondary, and fallback routes.
• Classify sites by operational and regulatory criticality (EDM, control, monitoring).
• Scope and assess Proteus to WITS Modern migration complexity and delivery implications.
• Conduct structured engagement with SCADA engineers and field technicians to capture undocumented operational knowledge.
• Lead Ofcom UHF spectrum and licence compliance assessment.
• Evaluate replacement telemetry bearer options against SCADA, latency, and protocol requirements.
• Lead and support lab and live-site PoCs, validating SCADA integration, data integrity, and failover.
• Input into target architecture, migration sequencing, and site prioritisation based on technical constraints.
Your Profile Essential skills/knowledge/experience:
• 5+ years' hands-on OT telemetry experience in regulated utilities or CNI environments
• Strong operational experience with utility SCADA platforms and historian data flows
• Proven expertise in RTU commissioning, configuration, and fault diagnosis
• Deep working knowledge of telemetry protocols:
• WITS Modern, Proteus
• DNP3, IEC 60870-5-101/104
• Modbus TCP/RTU
• Practical understanding of Legacy UHF radio telemetry and migration risks
• Solid knowledge of Ofcom radio licensing within the UK water sector
• Ability to operate credibly in live operational OT environments
Desirable skills/knowledge/experience: (As applicable)
• Experience in UK water sector PSTN retirement or 2G/UHF upgrade programmes
• Working knowledge of IEC 62443 and NCSC CAF applied to telemetry systems
• Direct experience with Ofcom spectrum management and licence transition planning
• Strong familiarity with GeoSCADA configuration, polling models, and historian feeds
• Experience supporting parallel-run migrations with zero service disruption
