Frontend Engineer, Agents

Hebbia is building the user interface for universal knowledge capture. The Frontend Engineer on Agents will own the interfaces for bankers, investors, and lawyers to work with AI agents, building real-time, data-dense UIs with TypeScript and React. The role requires deep front-end expertise and comfort working across the stack when needed.

• Design and build the agent-facing UI for Hebbia: streaming agent output, real-time progress over long-running tasks, citation and provenance views, checkpoint and approval flows
• Own front-end architecture for data-dense, real-time surfaces — hundreds of companies × thousands of documents — with rendering performance and state management that hold up at that scale
• Contribute to making mobile, a high-value surface for finance professionals, an excellent surface to talk to Max on the go
• Build the backend surface those UIs depend on: streaming and real-time endpoints, agent state and session APIs, Hebbia MCP tools, and the glue to new data integrations
• Partner with applied researchers to get new agentic capabilities in front of users quickly, then iterate using insights from eval frameworks
• Own quality end to end: accessibility, telemetry, testing, performance budgets, and a design system that scales across web and mobile

• Bachelor's degree in Computer Science, Engineering, or related field, or equivalent experience
• 4+ years building production front-ends at a venture-backed startup or top technology firm
• Expert in TypeScript and React, with a deep understanding of rendering performance, state management, data fetching, and real-time patterns
• Comfortable across the stack — designing APIs, working with async services, and debugging the systems behind your UI
• Strong product sense and design taste; comfortable working closely with designers and product managers
• Frequent user of AI products, especially during the development lifecycle (i.e. Cursor, Claude Code, etc.)
• Excellent problem-solving, communication, and teamwork abilities
