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 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 environments, you’ll help develop AI capabilities that support some of the UK’s most important national security missions.

Depending on your area of expertise, you could work across engineering, operations and applied research, evaluating AI-enabled systems, building prototypes, identifying and mitigating emerging threats, assessing technical risks, developing guidance, or helping to deploy AI securely in real-world environments.

We’re recruiting across a range of technical specialisms and disciplines. Depending on your background and interests, opportunities may include agent development, software and infrastructure engineering, AI security analysis and testing, cyber applications of AI, MLOps, workflow automation, solution architecture and cyber consultancy. Roles may also involve research into agentic frameworks, machine learning, generative AI and LLMs, as well as the development of data-driven insights, including with private sector organisations.

As your experience 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

About you
We’re looking for talented individuals who demonstrate how they have delivered meaningful impact through the application of AI technologies and/or the development of agentic solutions, ideally within large or complex team environments. You’ll bring experience leading technical delivery, setting direction and objectives, driving projects forward, and mentoring or developing others to achieve successful outcomes. Curiosity and a genuine interest in cyber security are important. You don’t need to be an expert in every area, but you should have the enthusiasm and aptitude to learn about a broad range of cyber topics and emerging technologies. We value people who actively develop their skills, whether through professional experience, personal projects, research, or cyber challenges and competitions.

You’ll have a good technical grounding and be comfortable learning and applying new technologies quickly. We’re particularly interested in candidates who can demonstrate experience in at least two of the following areas: software development, designing and building system architectures, and technical research and analysis. We value individuals who enjoy tackling complex problems, working across disciplines, and continuously developing new skills.

Collaboration is central to the way we work. You’ll be comfortable working with colleagues from a variety of technical backgrounds, both within and beyond the immediate team, and will be keen to contribute to a supportive, inclusive and high-performing environment.

You’ll be motivated by working at pace, balancing multiple priorities and delivering outcomes in a dynamic setting.

We welcome applications from people of all educational and professional backgrounds and have no formal qualification requirements. Instead, we’re interested in evidence of your technical ability, potential and achievements. Depending on the role and your skills, you may be eligible for specialist pay. These roles require 80% office attendance, subject to role requirements and business need.

Please note: The NCSC is advertising a number of roles at the moment. Please submit an application for each role you wish to be considered for. Applying for other roles will not be detrimental to your application for this role and, if you are successful in a number of roles, you will be able to choose which role you prefer at the point of conditional job offer.
