Operational and Surveillance
London, Manchester, Gloucestershire
At GCHQ, diversity and inclusion are critical to our mission. To protect the UK, we need a truly diverse workforce that reflects the society we serve. This includes diversity in every sense of the word: those with different backgrounds, ethnicities, gender identities, sexual orientations, ways of thinking and those with disabilities or neurodiverse conditions. We therefore welcome and encourage applications from everyone, including those from groups that are under-represented in our workforce.

Short Summary of role

This is an opportunity to join a growing team of telecoms security specialists. We are experts in our field who understand how networks can be compromised, and the mitigation techniques that make attacks less likely to be successful. Our mission is to use our knowledge to improve the security of the UK’s telecommunications sector.

This is an exciting time for telecoms security in the UK. The introduction of the Telecoms Security Bill provides a once-in-a-generation opportunity to boost the security standards of the UK’s telecoms networks. This new regime is underpinned by the detailed security analysis performed by the NCSC’s telecoms security team, and the team will be at the heart of its implementation over the coming years. Alongside the bill, we use our technical knowledge to support DCMS in diversifying the telecommunications sector, helping to address the national security risks due to the use of high risk vendors and the lack of diversity in the telecoms supply chain.

As one of the NCSC’s leads in telecoms security, you will have in-depth knowledge in telecommunications technology paired with expertise in security analysis. You will deliver security improvements across the telecoms sector by sharing your expertise with major UK operators, international vendors and the UK government. Clear and persuasive, you will be able to explain and contextualise complex technical details to effectively influence stakeholders.

You will take an evidence-backed view of security risk, using rigorous analysis, real-world incidents and known techniques to prioritise improvements. You will be able to justify known mitigations, innovating security solutions and mitigation strategies where appropriate.   
Taking the unique opportunities available to you as part of NCSC, you will gain a unique insight into the telecommunications sector. You will continuously grow your knowledge of telecoms security, be that through training, your own research, collaboration with industry and the wider intelligence community, or supporting the management of cyber incidents in the sector.

You will have a beginner’s mindset, eager to play with and understand new technologies, such as 5G, OpenRAN, Software-Defined Networking, Mobile Edge Compute, Trusted Computing or network automation.

What will the successful candidate be doing?

Depending on your skill set and interests, you will be working in one or more of the following areas:
•    Supporting Ofcom and DCMS to implement a new telecoms security framework for the UK, which will define the future security of the sector.
•    Direct technical security consultancy with UK operators and international vendors.
•    Advising stakeholders on telecoms threats, and defining mitigating solutions.

•    Fostering new telecoms and security companies by removing technical barriers that hinder innovation and vendor diversity.
