Job description

The role

AI is transforming how organisations design, build and defend technology — and the NCSC is looking for outstanding technical talent to research and build agentic solutions that improve the nation’s cyber security and help protect the UK.

We’re looking for talented AI technologists to join us across a variety of departments at the NCSC. You’ll be at the forefront of applying AI to some of the UK’s most important cyber security resilience challenges. You’ll help explore how increasingly capable AI systems can strengthen defence, improve security outcomes and enhance our understanding of adversaries. You’ll also support organisations across the public and private sectors to adopt AI confidence and contribute to the development of secure, resilient and innovative technology.

Working in highly specialised environments, you’ll help shape how AI is evaluated, developed, secured and deployed to support some of the UK’s most important national security missions. The work is varied, fast-moving and highly collaborative. You’ll combine technical expertise with a deep understanding of the mission to tackle complex challenges, helping GCHQ and NCSC remain at the forefront of evaluating, securing and applying AI for national security. By harnessing AI and agentic technologies, you’ll deliver tangible outcomes against some of the UK’s most pressing cyber and national security challenges.

These roles are supporting a wide range of GCHQ and NCSC missions. Working across engineering, operations, and applied research, you could be evaluating AI-enabled systems, building prototypes, detecting and mitigating adversaries, assessing technical risks, or supporting the secure deployment of AI in real-world environments. The work spans the full AI lifecycle, from research into machine learning, generative AI and large language models through to software engineering, solution architecture, MLOps and deployment. Working in multidisciplinary teams alongside engineers, researchers and cyber specialists, you’ll help turn innovative ideas into secure, resilient capabilities. As your expertise develops, you will provide technical advice across the public and private sectors and engage with leading technology companies to help keep the UK at the forefront of the secure and effective use of AI. Depending on your role and experience, you may also help shape technical strategy and influence decision-making across teams, and provide leadership on complex, mission-critical challenges.

The rapid evolution of AI means you’ll continually explore emerging technologies, develop new skills and adapt quickly to new opportunities and challenges. You’ll also have opportunities to deepen your understanding of a broad range of cyber security disciplines and apply your expertise in new and innovative ways.

This is an opportunity to be part of one of the most significant technological shifts of our time within the UK’s National Technical Authority for cyber security. AI is transforming both offensive and defensive cyber capabilities, shaping the future of intelligence mission and what it means to keep a nation secure.

We’re looking for people who combine technical expertise with curiosity, creativity and a passion for solving complex challenges. If you enjoy exploring new technologies, thinking ahead to future engineering challenges, and contributing to a mission that makes the UK safer to live and work online, we’d love to hear from you.
