This is a broad network engineering role. Alongside 'BAU' responsibilities, you will help deliver ongoing service improvements and contribute to the implementation of projects, ensuring that current and future requirements are met. If you are looking for a network engineering role where you can build on existing expertise, take ownership of your technical development, and play an active role in driving innovation, automation and service improvement, then this role could be a great fit for you. We are looking for engineers who are already operating at a strong level, with a proactive approach to learning through self-study, lab work and engagement with evolving network technologies. What You'll Do: * Take ownership of specific network systems and services, ensuring they are maintained throughout their lifecycle and meet defined availability, performance, security and supportability standards. * Ensure the smooth operation of services while adhering to agreed SLAs, taking accountability for escalated technical issues and delivering sustainable, well-understood resolutions. * Act as a strong communicator, building effective relationships with stakeholders across technical and non-technical teams to understand requirements, expectations and areas for improvement. * Work closely with project managers, stakeholders and delivery teams to understand both business and technical requirements, contributing to the successful delivery of network solutions. * Take ownership of technical delivery activities, ensuring solutions are implemented in a stable, scalable and supportable manner aligned to organisational standards. * Contribute to network design activity, working alongside our architecture team to provide input, feedback and practical implementation considerations. * Drive continuous improvement by identifying and implementing changes where services do not meet expected standards, or where there are opportunities to enhance performance, resilience, security or efficiency. * Proactively identify, assess and remediate security vulnerabilities across the network estate. * Provide technical expertise and guidance, influencing decisions on improvements, standards and future direction of services and technologies. * Maintain high-quality design, implementation and operational documentation to support ongoing service stability and knowledge sharing. To be considered for this role, you'll need to show us that you've got the skills and capabilities.
