Senior RTS Design Engineer

Are you a specialist in real time systems and operational communications for high‑voltage networks? Do you want to play a key role in designing the SCADA and communications infrastructure that enables safe, reliable operation of substations across the DNO network?

Department: OCU Design

Location: Ruislip

Key Responsibilities

RTS & SCADA Design

• Lead the development of real time systems designs, including SCADA architectures, RTU solutions, substation LANs, and communications topologies.
• Produce and review RTS design deliverables such as system architecture diagrams, communications topologies, LAN layouts, IED integration diagrams, and RTS design specifications.
• Define RTS requirements during early project stages and support feasibility and option selection.

Standards & Compliance

• Ensure all RTS designs comply with DNO policies, RTS standards, cyber and operational requirements, and project specifications.
• Interface with the DNO design authority to achieve timely approvals across all RTS submissions.
• Apply a consistent, auditable approach to design assurance and technical governance.

Communications & OTN Interfaces

• Design and coordinate RTS interfaces with operational telecommunications networks, including fibre, IP‑based communications, and OTN interfaces where applicable.
• Define requirements for data, protection, and control communications, ensuring resilience, redundancy, and operational security.
• Coordinate with telecoms and OT specialists to ensure end‑to‑end connectivity is achieved and documented.

RTUs, Panels & Integration

• Specify and integrate RTUs, control panels, communications equipment, DC supplies, and associated interfaces.
• Define I/O requirements, data mappings, and integration principles to support SCADA monitoring and control.
• Review and support configuration strategies to ensure consistency between design intent and deployed systems.

Multi‑Disciplinary Coordination

• Work collaboratively with primary electrical, protection, civil, and construction teams to deliver fully integrated substation designs.
• Provide RTS input to construction sequencing and commissioning strategies.
• Support technical queries during delivery and resolve RTS‑related design issues.

Construction, Testing & Commissioning Support

• Provide technical support during installation, testing, and commissioning of RTS equipment.
• Review test documentation, commissioning results, and as‑built information for RTS systems.
• Support system integration and handover to ensure RTS operates as intended within the wider network.

Technical Leadership

• Provide mentorship and technical guidance to junior RTS engineers.
• Review third‑party RTS designs and deliverables produced by sub‑consultants.
• Contribute to continuous improvement of RTS design processes, standards, and templates.

Skills, Knowledge & Expertise

• Degree (or equivalent) in Electrical Engineering, Control Systems, Communications, or a related discipline.
• Strong experience delivering RTS / SCADA designs for HV and EHV substations within a DNO or ICP environment.
• Proven background in substation communications, RTUs, SCADA integration, and operational networks.
• Experience working through full project lifecycles, from feasibility and detailed design to commissioning and handover.
• In‑depth understanding of Real Time Systems architectures in electrical substations.
• Strong knowledge of SCADA systems, RTUs, substation LANs, IP networking, and OTN interfaces.
• Ability to interpret and apply DNO RTS and telecommunications standards.
• Clear, confident communicator able to explain technically complex systems to non‑specialists.
• Strong attention to detail in producing and checking RTS drawings, specifications, and documentation.
• Able to work independently while contributing effectively within a multi‑disciplinary team.
• Well‑organised, with the ability to manage multiple projects and priorities in a delivery‑focused environment.
