Frontier Research Engineer, Security
<div class="content-intro"><h2>About the AI Security Institute</h2>
<p>The AI Security Institute is the world's largest and best-funded team dedicated to understanding advanced AI risks and translating that knowledge into action. We’re in the heart of the UK government with direct lines to No. 10 (the Prime Minister's office), and we work with frontier developers and governments globally.</p>
<p>We’re here because governments are critical for advanced AI going well, and UK AISI is uniquely positioned to mobilise them. With our resources, unique agility and international influence, this is the best place to shape both AI development and government action.</p></div><h2><strong>The deadline for applying to this role is Sunday 19th July 2026, end of day, anywhere on Earth.</strong></h2>

<h2><strong>Role Summary:</strong></h2>
<div class="scriptor-paragraph">
<p><span data-contrast="auto">We're looking for a strong software engineer who's drawn to security. Someone who would rather ship a paved road than write a policy, and who's excited by the prospect of building the security foundations for frontier-scale AI safety research. You don't need to be a career security specialist. You do need to be a genuinely good engineer who thinks adversarially, cares about getting the defaults right, and wants to go deep on security over the coming years.</span><span data-ccp-props="{"335551550":6,"335551620":6}"> </span></p>
<p><span data-contrast="auto">Working as a hands-on engineer on AISI's Security Engineering team, building the secure-by-default patterns, reusable controls, and guardrails that the rest of the organisation builds on top of. You'll spend at least your first year focused on platform and product security, embedding safe practices across the development lifecycle, hardening our cloud and CI/CD foundations, and partnering with engineers to fix classes of issues rather than one-off bugs.</span><span data-ccp-props="{"335551550":6,"335551620":6}"> </span></p>
<p><span data-contrast="auto">You'll build influence through enablement, not enforcement. Over time, you'll extend these patterns. We expect your security depth to grow on the job; we'll back that with mentorship, learning budget, and real ownership early.</span><span data-ccp-props="{"335551550":6,"335551620":6}"> </span></p>
