OT Edge Device Gateway Specialist
Position: OT Edge Device Gateway Specialist
Location: Coventry, UK (Hybrid 2 days onsite a week to office)
Duration: Long Term B2B Contract
Job Description:
We are looking for an OT Edge Devices & Gateway Specialist to support extended OT discovery and design activities, with a specific focus on CWQM (Clean Water Quality Monitoring) sensor integrations. The role requires deep, hands-on expertise in industrial/OT devices and gateways to recommend, evaluate, and select the most appropriate edge devices for reliable data acquisition from CWQM sensors.
The specialist will play a critical role in addressing current limitations in existing deployments, particularly where S2000 Nano devices from Ovarro are used and protocol support is constrained, impacting data ingestion and integration capabilities.
Key Responsibilities
Lead technical assessment and recommendation of OT edge devices and gateways suitable for CWQM sensor data acquisition.
Analyse existing CWQM sensor types, communication methods, and protocols to determine optimal edge/gateway options.
Assess limitations of currently used devices (eg, Ovarro S2000 Nano) and propose alternative or supplementary gateways with broader protocol support.
Define device-level data acquisition architecture, considering scalability, robustness, and integration with upstream OT/IT platforms.
Advise STW on device procurement strategy, including recommended vendors, models, and configuration considerations.
Support OT discovery workshops and technical deep dives with domain insights on field devices and edge computing.
Collaborate with OT, IT, and solution architecture teams to ensure end-to-end compatibility from sensor to central systems.
Document findings, recommendations, and design decisions in a clear, consumable format for stakeholders.
Required Skills & Expertise
Strong experience with industrial/OT edge devices and gateways used in utilities or industrial environments
Hands-on knowledge of sensor data acquisition and field connectivity in water or environmental monitoring contexts (CWQM preferred).
Proven understanding of industrial communication protocols, including but not limited to:
o OPC UA
o MQTT
o DNP3 (desirable)
o WITS
o Sparkplug B
Experience evaluating vendor devices and selecting fit-for-purpose gateways based on protocol support and deployment constraints.
Ability to assess Legacy or constrained devices and design pragmatic enhancements or alternatives.
Desirable Experience
Prior experience working with or alongside Ovarro S2000/S2000 Nano devices or similar RTUs.
Background in water utilities, environmental monitoring, or OT-heavy infrastructure programmes.
Familiarity with edge computing concepts and OT-IT data integration patterns.
Experience supporting discovery phases, assessments, or pre-delivery technical studies.
Key Outcomes
Clear recommendation of right-fit edge devices/gateways for CWQM sensor data acquisition.
Mitigation strategies for existing protocol limitations in current deployments.
Practical, vendor-aware guidance enabling STW to move confidently into extended OT delivery phases.
