About the role

Key responsibilities & impact

Design and ship core Eve framework features — the file-system conventions, compiler, and runtime that turn an agent directory into a durable, production-ready agent on Vercel.
Build and maintain integrations across Eve's channel layer (Slack, Web Chat, WhatsApp, API, Cron, and more) and connections layer (Vercel Connect / MCP endpoints).
Collaborate with the AI SDK, Workflows, and Sandbox teams to ensure Eve's primitives compose seamlessly on the Vercel platform.
Drive DX quality — CLI ergonomics, error messages, docs, and examples — so TypeScript/Next.js developers can ship their first agent in minutes.
Contribute to Eve's evaluation and observability story: test suites, scoring rubrics, and deployment-time evals that make agents production-safe.
Partner with early customers and internal teams to gather feedback, diagnose agent reliability issues, and iterate rapidly.

Familiarity with LLM APIs and agent orchestration patterns (tool calling, multi-agent delegation, human-in-the-loop flows)
