Software Engineer, Agent Stack at Vercel

About Vercel

Vercel is the agentic infrastructure company, empowering people and agents to ship what's next. For over a decade, we've influenced web development with products like Next.js, v0, and the AI SDK, helping builders move from idea to production with speed, security, and exceptional developer experience. We are now building the platform for the future where software is built, extended, and operated by agents, trusted by industry leaders like OpenAI, PayPal, and Ramp.

About the Role

We are looking for a Software Engineer to join the Agent Stack team and help build eve — Vercel's framework for building production-ready AI agents. Eve aims to be for agents what Next.js is for web apps: an opinionated, batteries-included framework that allows developers to focus on their agent's unique logic while the platform handles the rest. You will design and implement core framework primitives, contribute to eve's runtime (built on Vercel Workflows, AI SDK, and Sandbox), and shape the developer experience for the next generation of AI-native applications. This role reports to the Director of Vercel’s Agent Stack and is located onsite in New York City.

Note: If based within commuting distance of our SF, NY, London, or Berlin offices, in-office anchor days on Monday, Tuesday, and Friday are expected, even for roles listed as remote.

What You Will Do

• Design and ship core Eve framework features, including file-system conventions, compiler, and runtime, to transform 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, etc.) and connections layer (Vercel Connect / MCP endpoints).
• Collaborate with the AI SDK, Workflows, and Sandbox teams to ensure seamless composition of Eve’s primitives on the Vercel platform.
• Drive developer experience (DX) quality through ergonomic CLIs, clear error messages, comprehensive documentation, and helpful examples, enabling TypeScript/Next.js developers to ship their first agent in minutes.
• Contribute to Eve’s evaluation and observability, including test suites, scoring rubrics, and deployment-time evaluations to ensure agent production safety.
• Partner with early customers and internal teams to gather feedback, diagnose agent reliability issues, and iterate rapidly.

About You

• 5+ years of production TypeScript/JavaScript experience, with the ability to own complex, stateful systems end-to-end.
• Strong understanding of distributed systems concepts, including durable execution, checkpointing, async workflows, and failure recovery.
• Experience building or operating developer tooling, frameworks, or SDKs used by external developers.
• Familiarity with LLM APIs and agent orchestration patterns (tool calling, multi-agent delegation, human-in-the-loop flows).
• A track record of shipping high-quality open-source or customer-facing APIs, with a deep appreciation for API design.

Compensation & Benefits

• Base Pay Range (New York, NY): $208,000 - $312,000 per year. Actual salary will be based on job-related skills, experience, and location. Compensation may be adjusted based on employee location outside of San Francisco.
• Total Compensation: May include benefits, equity-based compensation, and eligibility for a company bonus or variable pay program.
• Vercel is committed to fostering an inclusive community. We encourage applications from all backgrounds and do not discriminate on any protected characteristic. We welcome candidates who may not meet every qualification but are excited about the role.
