Applied AI Scientist (MI6)

You’re an applied AI scientist with a strong technical foundation and a natural curiosity for how AI can solve meaningful, real world problems. You’ve developed, trained and deployed models before, and you’re confident working across the full lifecycle of modern AI techniques. You understand data, you understand systems, and you enjoy working close to users so you can see the impact of what you build.

Your experience means you can explore complex datasets, design prototypes and evaluate model behaviour with rigour. You’re comfortable working with natural language data, large language models and emerging agentic approaches, and you know how to test, benchmark and validate them effectively. You understand where AI adds value and where it doesn’t, and you’re thoughtful about how to introduce it into existing workflows in a safe, ethical and secure way.

You approach problems with a combination of analytical depth and practical judgement. You can explain technical ideas clearly to colleagues with different backgrounds, build positive relationships across mission, product and engineering teams, and translate operational needs into realistic AI opportunities. You’re comfortable navigating uncertainty, experimenting with new tools and assessing whether a technique is robust enough for its environments.

Always keeping up to date with emerging methods, you explore new technologies to understand their potential and are motivated to keep improving your craft. You care about building solutions that are reliable, responsible and genuinely useful, and you’re driven by the chance to contribute to work with real world mission impact across MI6.

We’re creating dedicated teams focused on bringing AI into some of our most mission critical areas, helping develop technologies that enhance how MI6 operates today and prepare us for the challenges of tomorrow. As an Applied AI Scientist, you’ll play a central role in that effort, engaging directly with real world operational workflows. You’ll understand the patterns AI needs to learn and identify where automation or augmentation can unlock new efficiencies and insights.

You’ll work closely with mission teams to understand their day to day tasks, data flows and analytical challenges, and to determine where AI can genuinely improve outcomes. Much of your work will sit at the exploratory edge of technology: prototyping ideas, testing hypotheses, evaluating open source tools and experimenting with new approaches. You’ll build proofs of concept, validate model behaviour and assess how different architectures can be deployed securely and ethically within our environment. Once approaches are validated, engineering teams will productionise and scale the solutions you’ve helped design.

You have experience of writing software at a level sufficient to ensure that your AI work can deliver real operational impact. Day to day, you’ll apply modern AI and data science techniques, from natural language processing and text classification to fine tuning and deploying large language models. You’ll rigorously evaluate model performance, explore agentic and workflow oriented AI, and help teams understand how these capabilities can augment human judgement. Ethical, secure and compliant use of AI is central to the role, and you’ll help shape how we steward these technologies responsibly across MI6.

You have also started to step into AI leadership, contributing to how AI is understood and applied. We’re open to this meaning different things for different people, depending on your skills and interests. For example, you might have a passion for being a role model and mentoring junior technologists as they grow as professionals. Or you might look wider, working with people from other, non-technical backgrounds and influencing AI adoption strategy in the wider organisation. Many people in this role do both. Either way, you’ll be part of a growing community shaping MI6’s direction in AI. As our capability evolves, you’ll contribute to decisions on tools, processes and best practice, helping us evaluate and adopt rapidly advancing technologies. There will be opportunities to work with global mission partners, attend conferences and stay at the forefront of developments in the wider AI ecosystem. This role offers significant scope to innovate, giving you the freedom to explore, experiment and make a tangible impact on how AI is used across MI6.
