We tailor this process as needed for each role and candidate. If you're applying to our technical roles, this privacy policy applies. * Non-technical roles: Our non-technical roles' process includes submitting a CV, 2-4 interviews including a conversation with leadership and sometimes presentation or take-home task assessments. While our interviews follow civil service requirements, we do not require answering in STAR or other rigid formats. We recommend preparing to speak about your past career experience and how you would approach problems you would face in your AISI role. Nationality Requirements & Visas * Technical roles: we can hire almost all nationalities and sponsor visas. * Non-technical roles: you must meet civil service nationality requirements (by having Commonwealth citizenship, indefinite leave to remain, EU settled status, or meeting some other criteria). National Security Vetting * Requirements vary by role and not all roles require vetting; check each job ad. * Counter Terrorism Check (CTC) and Security Clearance (SC) vettings usually require 2+ years of recent UK residency. Developed Vetting (DV) clearances usually require 10+ years., We're flexible on the exact profile and expect successful candidates will meet many (but not necessarily all) of the criteria below, * Strong Python skills with experience writing scripts for automation or security tooling * Proven experience in at least one of the following areas of cybersecurity red-teaming: * + Penetration testing + Cyber range design + Competing in or designing CTFs + Developing automated security testing tools + Bug bounties, vulnerability research, or exploit discovery and patching * Strong interest in helping improve the safety of AI systems, * Familiarity with virtualisation technologies such as Proxmox VE and infrastructure-as-code approaches to enable reproducible test environments to be rapidly spun up for testing * Ability to communicate the outcomes of cybersecurity research to a range of technical and non-technical audiences * Familiarity with cybersecurity tools such as network packet capture utilities, penetration testing frameworks, and reverse engineering/disassembly tools * Active in the cybersecurity community with a track record of keeping up to date with new research * Previous experience building or measuring the impact of automation tools on cyber red-teaming workflows, Successful candidates must undergo a criminal record check and get baseline personnel security standard (BPSS) clearance before they can be appointed. Additionally, there is a strong preference for eligibility for counter-terrorist check (CTC) clearance. Some roles may require higher levels of clearance, and we will state this by exception in the job advertisement. See our vetting charter here. ## Description 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. The 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. Role Description We are looking for exceptional cybersecurity experts at all experience levels, from junior through to senior or staff, who want to work at the forefront of frontier AI security. 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. Your day-to-day work might include building state-of-the-art evaluations (e.g., cyber ranges), running pre-deployment testing exercises (e.g., Claude Mythos Preview), validating novel model behaviours (e.g., models cheating in evaluations), and answering timely research questions (e.g., the capabilities of open-weight models). You would be working alongside engineers and researchers who care deeply about the impact of their work, take pride in their craft, and have a high level of autonomy. If that sounds exciting to you, we'd love for you to apply! Core Responsibilities * Evaluation Design & Development (60%) + Design cyber ranges and CTF-style challenges for automatically grading AI system performance on cybersecurity tasks + Build agentic scaffolding to evaluate frontier models, equipping them with tools such as network packet capture utilities, penetration testing frameworks, and reverse engineering/disassembly tools + Design metrics and interpret results of cyber capability evaluations * Infrastructure engineering (30%) + Work alongside other engineers to ensure evaluation environments are robust and scalable * Research & Communication (10%) + Write reports, research papers and blog posts to share findings with stakeholders + Keep up-to-date with related research taking place in other organisations + Contribute to AISI's broader understanding of AI cyber risks Example projects * Onboard and integrate new cyber ranges into our evaluation pipeline * Conduct agent research to improve the cyber capabilities of our agents * Improve grading and scoring methodologies for automated evaluation tasks * Integrate defensive telemetry and simulated users into ranges to increase their realism * Collaborate with government partners on joint research publications ## Related Videos - [Thinking Differently - How to Make Money from Cyber Attacks & Cheats](https://www.wearedevelopers.com/videos/745-thinking-differently-how-to-make-money-from-cyber-attacks-cheats) - [JavaScript?
