About the role

National Grid Electricity Transmission (NGET) is at the heart of energy in the UK. The electricity we provide gets the nation to work, powers schools and brings energy to life. Our energy network connects the nation, so it is essential that it is continually evolving, advancing, and improving.  

We’re passionate about both operating our network safely and providing highly reliable quality of supply for our customers. At the heart of achieving these outcomes is the effective control and operation of our network. 

As OT (Operational Technology) Network Development Manager, you’ll be responsible for leading the development of the OT Communication Network on a transformation journey where we manage and operate the network to a high security standard.  

Working with security, resilience, risk and compliance teams to secure the network and ensure it continues to operate safely, resiliently and with control, you’ll lead a team that are embracing leading technologies to secure the data flows to enable us to achieve our net zero goals whilst ensuring a resilient network. 

Accountable for the transition to High Bandwidth Overlay (HBO), you’ll be directly responsible for the oversight and management of the OT Operational teams, including Field Engineers and the Network Management Centre (NMC). 

You’ll have complete end to end responsibility for the network including overseeing and helping to foster a culture of effective change management, operational fault finding, security and resilience. 

You’ll be accountable for the service availability and resilience standards, with ownership of incident triage and root cause analysis investigation and resolution to minimise network related downtime.  

You’ll initially be based out of our Warwick office for 3 days per week, moving to the Midlands office in the future.  Office working can be combined with hybrid working from home. 

What you'll need

With a good understanding of IT cyber security and a strong track record of managing network security technical projects, you’ll have experience of managing the design and implementation of L2 networks including ethernet, fibre and wireless.  

Experience in Networking, complex IT administration or OT, is preferred, however, if you can demonstrate a passion for Network security and have evidence of hands-on experience we would like to hear from you.  

First class communications skills and experience of working closely with executive-level stakeholders 

across different areas of the business is essential, as is significant experience leading major and minor project deliveries in a network environment. 

You’ll be self-motivated and proactive, able to think strategically to develop and implement business plans according to targets and timeframes, coupled with experience in managing teams of technical network engineers spread across different UK locations. 

Interpersonal and presentational skills, along with significant experience of working within and across teams in complex environments is key, as is experience of influencing outsourced services, setting direction, control and standards, ideally in operational network environments. 

You will also need analytical and problem-solving capabilities. Strong knowledge of telecommunications technology and systems is highly desirable. e.g. SDH, MPLS, IP Networks.
