We are representing a confidential AI infrastructure organization seeking a Staff Frontend Engineer to own and evolve their platform's web experience in London. In this role, you will:

• Own the frontend end-to-end, including component architecture, design system evolution, performance optimization, and production operations for data-heavy, workflow-centric web applications
• Design and build intuitive user interfaces for complex engineering workflows, enabling users to design experiments, compare runs, interact with agents, and convert test data into actionable decisions
• Collaborate closely with Design, Product, and Backend Engineering teams to shape API contracts and integrate advanced AI capabilities safely
• Structure large-scale React/TypeScript frontends across modules, state management, routing, and data-fetching patterns
• Build visualization-centric UIs, dashboards, charts, time-series metrics, and experiment explorers for complex datasets
• Drive frontend developer experience improvements and maintain high testing standards across unit, integration, and end-to-end testing frameworks
• Mentor engineers across the wider organization on frontend engineering craft and best practices
• Integrate frontends with REST or GraphQL APIs while maintaining deep understanding of service-oriented architecture and data modeling

• 7+ years of professional software engineering experience with a proven track record of building, maintaining, and architecting complex, data-heavy web applications at Senior or Staff scope
• Advanced proficiency in React, TypeScript, and web fundamentals
• Deep experience structuring large-scale frontends and proven background building visualization-centric UIs for complex datasets
• Hands-on experience integrating frontends with REST or GraphQL APIs
• Strong understanding of service-oriented architecture, data modeling, and Python web frameworks (FastAPI, Flask, or Django)
• Practical experience with database data flows (PostgreSQL), cloud/container infrastructure (Docker, Kubernetes), and frontend observability tools (Sentry, Datadog, OpenTelemetry)
• Strong habits around testing frameworks and CI/CD pipelines, plus expertise with frontend build tooling (Storybook, design systems)
• Excellent communication, cross-functional collaboration, and mentoring skills in high-ambiguity environments

Preferred qualifications:

• Experience building B2B SaaS UIs for technical audiences (ML engineers, data scientists, or test engineers)
• Exposure to ML/AI workflows, experiment tracking, and agentic interfaces
• Hands-on experience with GraphQL, typed API clients in React, or SSR/SSG performance-focused frameworks
