Description

This is a job that Jill, our AI Recruiter, is recruiting for on behalf of one of our customers. She will pick the best candidates from Jack's network. The next step is to speak to Jack. Senior Frontend Engineer Company Description: VC-backed AI security startup Job Description: As the first dedicated frontend engineer, you will own the UI/UX for a systems-heavy AI security platform. You will build mission-critical dashboards, configuration screens, and analytics interfaces that provide visibility into agentic AI. Working closely with the CTO, you will shape the standards for enterprise-grade applications in a high-growth environment. Location: London, UK Why this role is remarkable: Significant impact as the first frontend hire with a clear path toward future leadership and ownership. Backed by top-tier global VCs in one of the fastest-growing sectors within artificial intelligence. High-trust, low-process work environment where frontend work is respected as core engineering rather than just visuals. What you will do: Architect and build complex dashboards, onboarding flows, and data-heavy analytics interfaces for AI security tools. Define frontend standards, establish UI component libraries, and own state management and API contracts. Collaborate with backend engineers to bridge the gap between high-level AI engine logic and user-facing policy design. The ideal candidate: Professional experience building and shipping non-trivial enterprise UIs using TypeScript and modern frameworks like React or Vue. Strong fundamentals in state management, API integration, and reasoning about edge cases in data-heavy applications. Comfortable with ambiguity and eager to help define product requirements in a fast-paced, high-autonomy startup setting. Who are Jack & Jill? Ok, I'll go first.

We never post fake jobs This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description. We appreciate this can make them look a bit suspect, but there isn't much we can do about it. Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
