About the Project

We're forming a dedicated delivery squad for a high-growth international technology client. The goal is to move customer support from reactive to proactive. The new platform will detect service issues from the client's operational data, assess their business impact, trigger remediation, and let affected customers know before they have to ask.

It's a greenfield, data- and AI-driven build on Google Cloud, delivered in phases. It starts with incident detection and human-approved remediation, then adds more granular detection and broader automated actions, and ends with a closed-loop system that acts autonomously within defined safety limits. You'll join a squad of around nine people, including a Solution Architect, data, ML, backend, frontend, UX, QA and platform engineers, working in the client's own tooling (Jira, Git, CI/CD).

The Role

You'll build the screens operators use to make and oversee high-stakes decisions: an incident approval console that shows blast radius and cost before anything is changed, a KPI dashboard, and later drilldowns, analytics and an agent console. You'll work closely with a UX designer and turn their designs and design system into a fast, clear and reliable product.

What You'll Do

• Build the incident approval console, integrated with the workflow and remediation services, including blast radius, cost and model confidence previews.

• Build a custom KPI dashboard and implement a shared design system with the UX designer.

• Deliver geographic and operational drilldown views and approval previews for new remediation types.

• Build the AI agent console, analytics and strategic reporting views in later phases.

• Work through user acceptance testing fixes and go-live hardening for each release.

• Contribute to frontend architecture, testing strategy and code quality across the squad.

What You'll Bring

• Strong commercial experience building production web applications with a modern framework such as React and TypeScript.

• Experience building data-heavy interfaces: dashboards, tables, filtering and data visualisation.

• Experience implementing or maintaining a component library or design system.

• Comfort integrating with REST APIs and handling real-time or frequently refreshing data.

• Good testing practice (unit, component and end-to-end) and attention to accessibility and performance.

• A collaborative approach to working with UX and backend engineers.

Nice to Have

• Experience building operational or internal tools where users approve or monitor automated actions.

• Experience with charting and mapping libraries (e.g. D3, ECharts, Mapbox).

• Exposure to deploying frontends on Google Cloud.
