You’ll join OCU’s design function at the forefront of the UK’s high-voltage infrastructure, shaping the real-time systems and communications networks that enable safe and reliable operation of substations across the DNO network. Working across projects from 11kV to 132kV, you’ll play a key role in delivering SCADA and RTS designs that support the evolving demands of the energy transition.
This is an opportunity to take a senior technical position within a growing organisation, where you’ll lead complex design solutions, influence standards and work on projects that are critical to the resilience and modernisation of the UK’s power network.
You’ll lead the design and development of real time systems and SCADA architectures for substation projects, ensuring solutions are robust, secure and aligned to DNO standards. Working across the full project lifecycle, you’ll define requirements at feasibility stage through to supporting commissioning and final handover.
You’ll produce and review detailed design deliverables, including system architecture diagrams, communications topologies and integration models, ensuring clarity, accuracy and compliance throughout. You’ll work closely with electrical, protection and telecoms specialists to deliver fully integrated designs that align with both operational and technical requirements.
A key aspect of your role will be ensuring all RTS designs meet industry standards and governance requirements, working with DNO design authorities to gain timely approvals and applying a consistent approach to technical assurance. You’ll also define and coordinate communications interfaces, ensuring reliable connectivity across fibre, IP-based networks and OTN systems.
You’ll support the specification and integration of RTUs, control panels and associated systems, ensuring effective data mapping and SCADA functionality. Alongside this, you’ll contribute to construction, testing and commissioning phases, providing technical guidance and supporting successful system integration.
As a senior member of the team, you’ll provide technical leadership, mentoring junior engineers, reviewing third-party designs and contributing to the continuous improvement of design processes, standards and technical delivery across the function.
