About Refractal Refractal is an AI security company building the infrastructure organisations need to defend against autonomous AI threats. 2026 has shown that generally capable intelligence is here. The challenge now is modernising security to stop AI-enabled threats, whether they come from internal agents going rogue or from attackers using AI to become more dangerous. Refractal was founded on cybersecurity and AI expertise from MIT, Microsoft, NASA and the U.S. Navy. Our product lets organisations detect AI-enabled threats at low cost without sacrificing detection quality. We take a practical approach to AI risk, combining proven cybersecurity methods with frontier AI security research. Today, we work with governments and organisations that can't afford to get security wrong. We're backed by leading deep-tech and cybersecurity investors and are growing the team to deliver on this mission. The role You'll lead product design at Refractal, covering the operator console, policy authoring, investigation and audit views, and the design system behind them. Your work will shape how security, risk and compliance teams find and respond to AI threats. What you'll do Design core workflows, including policy authoring, real-time triage, investigations and audit reporting. Turn dense technical data, such as agent activity, detections and evidence, into clear, fast interfaces. Build and maintain our design system in Figma, and work with engineers to ship it in React. Run research with security analysts, compliance leads and engineers at customer organisations. Shape our brand and website visuals with our content and marketing lead. Success in your first six months Core console workflows have been redesigned, shipped and measurably improved for analysts. A design system is in use across the product, with engineers building from it directly. Customer research is a regular input to product decisions. About you: essential 5+ years of product design for B2B or technical products, with a portfolio of shipped work linked in your application. Strong interaction and visual design, with expert Figma skills in components, variants and prototyping. Experience designing data-heavy tools such as dashboards, consoles, and developer or security products. Comfort working directly with engineers, with a good grasp of front-end constraints. Confident use of AI tools in your own design workflow. Nice to have Design experience on security, observability or compliance products. Front-end prototyping in code. Our values Radical transparency. We believe the best work happens when everyone feels able to give and receive honest, constructive feedback. Public service. We see AI security as a form of public service. Getting the AI transition right means putting the right infrastructure in place to manage the threats that come with it, and our work helps protect the institutions and services society depends on. Fail fast. We test ideas early, seek feedback and learn quickly. We experiment rapidly and change course when something isn't working, without compromising on security. Pragmatism, not dogmatism. We choose approaches based on how well they solve the problem. That means combining established cybersecurity methods with frontier AI research, questioning our assumptions, and changing our minds when the evidence changes.
