Work Authorization: We are looking for aSenior Full Stack Engineer with deep frontend expertise in React and TypeScriptto build enterprise-grade product experiences incorporating agentic AI capabilities. This is a hands-on engineering role requiring strong UI/product development skills, backend integration capability, and experience building applications from scratch. The ideal candidate can translate agent capabilities into polished enterprise user experiences while also understanding how agents, tools, APIs, state, and backend services work underneath the UI.

Responsibilities: Design and build enterprise applications and product features from scratch. Own full-stack feature delivery from UI architecture through backend/API integration, testing, deployment, and production support. Build sophisticated enterprise user experiences usingReact and TypeScript. Design reusable UI components, application state patterns, workflows, and interactive experiences around AI/agent capabilities. Build interfaces for multi-step agent workflows, agent actions, approvals, results, status, errors, and human-in-the-loop interactions. Integrate frontend applications with backend services, APIs, agent orchestration layers, and enterprise systems. Contribute to backend development as required for end-to-end feature ownership. Build and integrate agentic capabilities involving tool calling, multi-step workflows, context/state, retrieval, and enterprise actions. Ensure agent experiences expose appropriate user controls, validation, failure states, and escalation mechanisms.
