We’re growing strongly in the UK with increasing global momentum. With Agentic AI live in production, Keepnet runs autonomous systems that plan, build, and operate security awareness and human risk workflows — supported by strong guardrails, auditability, and observability. We’re looking for a Senior Front-end Developer who wants to build production-grade web experiences that power these systems — in an AI-first engineering team where quality, ownership, and long-term thinking matter. What You’ll Do • Build and own key parts of Keepnet’s web application (Vue/Nuxt), including performance, reliability, and maintainability., • Design and develop clean, modular UI components and shared packages (design system patterns, reusable modules)., • Implement AI-driven user experiences: human-in-the-loop approvals, guardrails-aware UI, clear feedback loops, and audit-friendly flows., • Integrate with internal APIs (and relevant third parties) to enable automation, reporting, and security workflows., • Create resilient UX for async workflows (jobs, queues, long-running tasks): polling, retries, idempotent actions, progress states, and error recovery., • Improve and maintain frontend observability (client-side logging, metrics, tracing where applicable; tools like Sentry) to prevent incidents rather than react to them., • Write and maintain automated tests across levels (unit/component and E2E) to increase release confidence., • Collaborate closely with Product, Design, Backend, and Customer-facing teams to ship features that solve real customer problems., • 5+ years building modern web applications for production SaaS., • Strong experience with Vue.js (Vue 2 & Vue 3) and Nuxt (Nuxt 2/3). (If you’re strong in Vue and can ramp quickly on the other, that’s ok.), • Solid knowledge of TypeScript, modern JavaScript, and browser fundamentals., • Strong understanding of API integration and real-world frontend architecture (state management, routing, data-fetching patterns, error handling)., • Ability to build for reliability: monitoring, debugging, incident hygiene, and continuous improvement., • Experience improving performance (Core Web Vitals, bundle optimization, SSR/CSR trade-offs, caching strategies)., • Experience with frontend testing (unit/component + E2E) and setting pragmatic quality bars., • Comfortable taking ownership beyond deployment: you ship it, you support it., • Hands-on experience using AI-assisted development and design tools such as Cursor, Figma Make, or similar — using AI daily for coding, refactoring, UI generation, and iteration, while maintaining strong engineering judgment and code quality. Nice-to-haves • Experience with Azure-based delivery pipelines (CI/CD) or cloud-native environments., • Experience with design systems (Storybook), and strong collaboration with Figma workflows., • Familiarity with accessibility (WCAG) and internationalisation (i18n, including RTL languages)., • Familiarity with React (helpful for cross-team collaboration, not required). Security mindset (important) • You build systems that are secure by design: XSS/CSRF awareness, safe auth/token handling, dependency hygiene, and careful data display. Tech Stack (Current) • Frontend: Vue (2 & 3), Nuxt, • Cloud / Delivery: Azure (CI/CD), • Observability: Sentry (and related logging/monitoring patterns) (We don’t expect you to know every tool on day one — we care about fundamentals and ownership.) Life at Keepnet Engineering at Keepnet is about craft, collaboration, and impact. What you can expect: • Hybrid working: In-office collaboration + remote focus time, • Thoughtful engineering: Time to design systems properly, not just ship quickly, • Global context: Work on a multinational platform used across multiple regions, • AI-first environment: AI-assisted development and production-grade AI systems are part of everyday work, • Team culture: Monthly team lunches and quarterly offsites, • Care about clean architecture, maintainability, and product quality, • Enjoy working with experienced peers who challenge each other constructively, • Prefer preventing incidents over reacting to them, • Want to build software used by real customers at real scale, • Believe good engineering is as much about ownership and judgment as it is about code If that sounds like you, we’d love to talk.
