Responsibilities

• Build and evolve core product surfaces, including
• Agents/Workflows visual builder (nodes, tool-calling, human-in-the-loop)
• Documents & Search UI (citations, compare/redline, basic redaction)
• Connectors wizards (Microsoft 365, etc.) with consent/scope flows
• Models/Gateway settings (routing, guardrails, budgets)
• Good engineering practices: Implement spec-first development, consuming OpenAPI-generated clients and ensuring contract consistency and backward compatibility. Maintain a high standard of quality: unit/component tests (Vitest, Testing Library), end-to-end Playwright tests on preview environments, and robust error handling and retry logic. Ensure accessibility (WCAG 2.1 AA) and usability across all features.
• Performance & UX: optimise for responsiveness and speed using techniques such as code-splitting, lazy loading, skeleton states, and optimistic UI. Monitor and maintain frontend performance budgets and leverage browser tracing (OpenTelemetry) to identify and resolve bottlenecks.
• Security & privacy: implement secure-by-design UI patterns, including OIDC/SSO authentication flows, role-based UI gating, and safe handling of telemetry data. Adhere to security requirements and follow secure development best practices to prevent data exposure.
• Collaboration & developer experience: Contribute to component library and design tokens, improving reusability and consistency across product surfaces. Maintain Storybook documentation and page/route templates to support both internal development and external SDK/extension partners. Participate in trunk-based development, using feature flags and Argo Rollouts canaries to ship continuously and validate releases in real environments.

Qualifications

• Experience : 4+ years of experience building modern web applications using React or Vue (Composition API) and TypeScript.
• Frontend architecture : Proven ability to design and implement complex, data-heavy UIs such as workflow builders, wizards, or document review interfaces. Experience working in contract-first or spec-driven development environments.
• Testing discipline: Strong background in automated testing, including unit, component, and end-to-end testing with Jest/Vitest and Playwright.
• Security, performance and accessibility awareness: familiarity with secure UI development practices (auth flows, access controls, data redaction, OWASP Top 10), WCAG accessibility principles and experience with web performance optimization, lazy loading, code-splitting, etc.
• Comfortable working with continuous delivery pipelines, feature flag systems, and rollout monitoring. Can work effectively with UX designers, backend engineers, and product managers; capable of making independent design decisions when needed.
• Exposure to Shacdn, Vite, Pinia, React/Vue Router, Storybook, Tailwind or design tokens, and AI-driven product surfaces (RAG, model gateways, document search) as well as experience in legal workflows is an advantage.

What We Offer

• Impact & Ownership: A leading role shaping the user experience of an AI-driven platform redefining legal technology. Your work will directly influence how customers interact with complex AI systems.
