Staff Software Engineer - UI

What You'll Do:

• Define and implement robust, scalable front-end architectures for complex data and AI-driven applications, utilizing tools like AG Grid and modern charting/visualization libraries.
• Set the technical direction, driving architectural leverage to significantly scale the system and ensure a future-proof design.
• Design and develop high-quality UIs, and strategically implement significant performance optimisations (e.g., Core Web Vitals, bundle size reduction).
• Establish and enforce best engineering and coding standards, driving code quality through rigorous code reviewing and mentorship.
• Proactively design monitoring/alerting strategies, leveraging Grafana and other monitoring tools to diagnose bottlenecks and ensure application stability.
• Actively mentor senior and junior engineers, fostering a culture of ownership and continuous technical learning.
• Lead cross-team collaboration with Product, UX, and Backend to define technical roadmaps and deliver integrated features.
• Set the standard for cross-browser compatibility and accessibility compliance across all UI components.
• Serve as a technical leader in the agile environment, influencing priorities and ensuring predictable feature delivery.
• Champion the effective and responsible use of AI-assisted development across the team, ensuring AI-generated code meets quality, testing, and security standards.
• Design resilient UI patterns for non-deterministic AI outputs — loading/”thinking” states, optimistic rendering, graceful fallbacks, and error/retry handling — to keep perceived performance high despite variable AI latency.

Who You Are:

• 8+ years of progressive front-end development experience, with a track record of leading and delivering large-scale, complex UI projects.
• Deep expertise in React, Typescript, and modern Vanilla Javascript (ES6+), with in-depth knowledge of framework internals and performance techniques.
• Proven experience with GraphQL, React Apollo, and state management libraries like Zustand, including designing efficient data architectures.
• Expertise in configuring and optimizing build pipelines using module bundlers/build tools such as Vite or Webpack, and experience with lerna or similar monorepo management.
• Excellent debugging skills with the ability to diagnose and resolve production issues across the entire stack.
• Demonstrated experience mentoring senior and mid-level engineers and defining technical roadmaps for front-end architecture.
• Experience with architecting and owning CI/CD pipelines and deep expertise in designing robust component library architectures utilizing SCSS/Sass and Tailwind CSS (or similar styling solutions) is preferred.
• Demonstrated ability to implement and drive strategy for application analytics and user behaviour tracking using tools like Google Analytics or Pendo (preferred).
• Proficiency with AI-assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot) to accelerate delivery and tech-debt reduction, with strong judgment on reviewing and validating AI-generated code against engineering standards.
• Experience building interactive data visualizations and dynamic/generative UI components (charts, cards, dashboards) that render structured outputs from APIs or AI/LLM responses.
• Familiarity with real-time UI patterns (streaming responses, SSE/WebSockets) and integrating UIs with agent/tool-driven or MCP-style backends is a strong plus.
