Successful candidates will have a unique experience working on or supporting the latest ground-breaking cyber security and networking technologies on a national and international scale. This opportunity will allow those involved to have first-hand exposure to the latest technologies via the research and development that we are undertaking to secure our telecommunications networks, in order to keep the UK the safest place to live and do business online. It also gives exposure to senior government department officials, communications industry leaders and academic professionals... all key stakeholders in the work of UKTL as you help UKTL's leaders to coordinate meetings and briefings.
As a trusted and independent national capability, the UKTL will interact at the intersection of standards bodies, such as 3GPP, the National Cyber Security Centre and the wider UK intelligence community, academia, Ofcom, as well as Communications Service Providers and telecommunication equipment vendors.
We are looking for a seasoned RAN (Radio Access Network) Engineer to join our team to provide expert support to our networks and services, ensuring that our ongoing capability to provide mission critical services to both our own Evaluation and Testing team, as well as national stakeholders remains of the highest quality.
You will be joining our Lab & Test Network Team at a pivotal time in the development of the lab – still in a “start-up” stage. As a RAN (Radio Access Network) Engineer, you will play an important part in helping us deliver success to our mission. Working with the wider Networks and Infrastructure team, you will have the opportunity to have direct influence over how the lab evolves and develops, ensuring that our networks and capabilities are representative of the UK telecommunications landscape and that we remain ahead of the game when it comes to new technologies. Our goal is to provide technical and testing services to the UK telecommunication landscape to help ensure that our Critical National Infrastructure remains secure in the face of ever present and evolving security threats.
Successful Applicants must be able to commute to the UKTL offices in Birmingham with the possibility of hybrid working.
