Requirements
* You’re an experienced cyber or information security practitioner with a strong background in designing and assuring secure systems in complex environments. Your experience includes security architecture or senior security engineering roles, and you’re comfortable taking responsibility for technical security decisions that influence how systems are built
* You bring hands on experience working with AI enabled technologies and understand the security challenges they introduce. This may include exposure to machine learning, large language models or cloud based AI services, particularly within AWS environments. You’re familiar with risks such as model integrity, provenance, poisoning and misuse, and understand how security controls must adapt as these technologies evolve
* In an evolving technical landscape where precedent is limited and risks continue to emerge, your judgement and critical thinking are essential. You’re able to operate where standards, controls and threat models are still developing, applying sound reasoning to make defensible security decisions
* You’re confident working directly with engineers, data scientists and ML practitioners, reviewing detailed technical designs and providing clear, actionable guidance on implementing secure patterns and controls. While deeply technical, you can also explain risk, trade offs and impacts in straightforward language, helping non specialist stakeholders make informed decisions
* Above all, you’re proactive, curious and motivated to stay ahead of emerging AI security challenges, valuing continuous learning and contributing specialist expertise within a small, collaborative team
* To work at MI6, you need to be a British citizen or hold dual British nationality.
What the job involves
* AI is being adopted across some of the most mission critical areas at MI6, creating a rare opportunity to influence how these technologies are secured from the start. As an AI Security Architect, you’ll help shape how AI systems are designed, deployed and governed in environments where security, trust and resilience are essential
* As part of a small, specialist team, you’ll take responsibility for the technical security architecture that underpins AI solutions across the organisation. You’ll define secure AI reference architectures, patterns and controls, and guide delivery teams on how these should be implemented in practice. Operating close to delivery, you’ll influence design decisions early and ensure AI is built to be secure by default
* The role sits at the intersection of established cyber security practice and rapidly evolving AI technologies. You’ll assess the security implications of capabilities such as machine learning and large language models, considering risks related to model integrity, provenance, poisoning and misuse
* Day to day, you’ll work closely with software engineers, data scientists and ML engineers, reviewing technical designs and providing practical, actionable feedback. You’ll also support assurance and accreditation colleagues, helping them understand complex architectures and clarify how security controls meet broader objectives. While most of your time is hands on and technical, you’ll engage with senior leaders as needed to explain risks, trade offs and the value of proactive investment in AI security
* This is a rare chance to help define how AI security is approached at organisational scale. As an individual contributor, you’ll shape emerging practice, influence standards and ensure AI capabilities are introduced in a secure, responsible and sustainable way
