Requirements
- 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.)

Nice To Haves
- You've shipped native mobile apps and understand the App Store release cycle end to end

Responsibilities
- 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.
