Job description

The role
AI is transforming how organisations design, build and defend technology — and the NCSC is looking for outstanding technical talent to help protect the UK in ways that only we can. Join us to research, develop and deploy agentic solutions that strengthen the nation’s cyber security and resilience.

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 and 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 and classified environments, you’ll help design, build, deploy and scale intelligent solutions that transform how people work, learn and interact with technology. You’ll work alongside multidisciplinary teams and some of the world’s leading cyber experts to advance AI capabilities and turn breakthrough ideas into production-ready systems that support some of the UK’s most important national security missions.

These roles support a wide range of GCHQ and NCSC missions, offering opportunities across engineering, cyber operations and AI security and applied research. Depending on your expertise, you could develop AI-enabled systems and agents, assess and secure AI technologies, apply AI to complex cyber security challenges and build and deploy innovative capabilities, or conduct research into emerging technologies and threats.

We’re recruiting across a range of technical specialisms and disciplines. Depending on your background and interests, opportunities may include:

• Agent development, software engineering, infrastructure engineering and solution architecture.
• AI security, agentic security analysis, assurance and security testing.
• Applying AI to cyber security challenges, including threat detection, vulnerability research and malware analysis.
• MLOps,workflow automation and deployment of AI-enabled capabilities.
• Research into machine learning, generative AI, LLMs and agentic systems, alongside cyber consultancy and data-driven insight.

As your expertise grows, you’ll have the opportunity to collaborate with some of the world’s leading organisations, helping us stay at the forefront of AI innovation and its application to cyber security. You’ll also work alongside multidisciplinary teams and some of the UK’s leading cyber specialists to turn emerging ideas into operational capability.

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 missions 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.

Person specification
