Senior Full Stack Engineer

The role

You will build the product experience for an enterprise platform: dashboards, a chat interface, persona-based layouts, and the API layer that connects the UI to agent and data layers. You will also own internal workflows for finance sign-off and platform governance.

What you will do

• Build the NextJS web app: dashboards, chat interface, and persona-based views.
• Implement data-heavy UI patterns: tables, drilldowns, charts, and exports.
• Ensure accessibility, usability, and a consistent experience across personas.
• Build and maintain a NestJS Backend-for-Frontend (BFF) layer connecting the UI to agent and data services.
• Treat BFF APIs as versioned platform contracts and manage changes cleanly.
• Implement role-based access control (RBAC) in the UI so views adapt to tenant-scoped access boundaries.
• Work with AI engineers to pass context safely and render structured responses.
• Own internal workflows that enable finance sign-off and platform governance.

Required qualifications

• 3+ years of full stack development with React/NextJS.
• TypeScript is mandatory.
• Experience with FastAPI for BFFs.
• Comfort with auth flows (JWT) and multi-tenant UI design.
• Strong UI engineering craft: clean component systems and reusable design.
• Practical approach to performance and data rendering at scale.
• Strong collaboration across AI, data, and DevOps teams.

Nice to have

• Experience with NestJS (or equivalent BFF patterns).
