Software Engineer - Cyber & Autonomous Systems Team - Job Hub - Epelcon Global: Long Life and Prosperity for All.

Job Description

<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><div class="vac_display_field"> <div class="vac_display_field_value"> <div class="vac_display_field"> <div class="vac_display_field_value"> <h2><strong></strong></h2> <h2><strong>The deadline for applying to this role is 11th October 2026, end of day, anywhere on Earth.  </strong></h2> <h2><strong><br>About the team</strong> </h2> <p></p> <p class="text-node">AI capabilities in cybersecurity and autonomy are advancing faster than at any point in history. Frontier models can now work through multi-step network intrusions, discover and exploit software vulnerabilities, and carry out long-horizon technical tasks with increasing independence. These are extraordinary tools for scientific and economic progress, but also have the potential for serious harm if misused or deployed without adequate oversight, as seen in the recent cybersecurity incidents.</p> <p class="text-node">Our Cyber & Autonomous Systems Team evaluates the capability of both frontier and open-weight AI models in cybersecurity, autonomy and AI R&D, ensuring the UK government and its partners have an accurate view of risks and capabilities. We use realistic cyber ranges and a large CTF suite for our evaluations, run pre-deployment testing of frontier models, and collaborate with our partners across UK government, frontier labs, and NCSC.</p> <h2><strong>Role Description</strong></h2> <p><strong></strong></p> <p class="text-node"></p> <p class="text-node">We are looking for exceptional Software Engineers at all experience levels, from junior through to senior or staff, who want to work at the forefront of frontier AI security</p> <p class="text-node">In this role, you’ll work with cutting-edge technologies on research problems with real-world impact, and receive mentorship and coaching from your manager and the technical leads on your team.</p> <p class="text-node">Your day-to-day work might include building state-of-the-art evaluations (e.g., <a href="https://arxiv.org/pdf/2603.11214" target="_blank">cyber ranges</a>), running pre-deployment testing exercises (e.g., <a href="https://www.aisi.gov.uk/blog/our-evaluation-of-claude-mythos-previews-cyber-capabilities" target="_blank">Claude Mythos Preview</a>), validating novel model behaviours (e.g., <a href="https://www.aisi.gov.uk/blog/cheating-behaviour-in-frontier-model-evaluations" target="_blank">models cheating in evaluations</a>), and answering timely research questions (e.g., <a href="https://www.aisi.gov.uk/blog/how-far-behind-the-frontier-are-leading-open-weight-models-on-cyber" target="_blank">the capabilities of open-weight models</a>).

The evaluations you build will help determine how advanced AI systems are assessed before deployment.</p> <h2><strong>Who we're looking for</strong></h2> <p>We're flexible on the exact profile and expect successful candidates will meet many (but not necessarily all) of the criteria below:</p> <h3><strong>Essential </strong></h3> <ul> <li>Delivering and maintaining production-quality
