Job summary

Vercel in San Francisco is seeking a senior software engineer to design and ship V—the primary agentic interface that helps users and systems get work done across Slack, web, and other surfaces. You will collaborate across product, data, and infrastructure teams to translate complex workflows into polished, reliable experiences that feel intuitive and fast.

The role emphasizes end-to-end ownership: building the agent architecture, enabling intent understanding, tool selection, memory management,

Qualifications

• 7+ years of full-time software engineering experience.
• Strong proficiency in TypeScript.
• Experience across UI and backend, APIs, queues, databases.
• Familiarity with agent-based systems is a plus.

Responsibilities

• Design and build V as the primary agentic interface for getting work done across Vercel, from answering questions and analyzing data to executing complex, multi-system workflows.
• Build the agent architecture that allows V to understand intent, plan work, select the right skills and tools, recover from failures, and complete long-running tasks reliably.
• Ship polished experiences across Slack, web, and other surfaces, combining natural-language interaction with rich, interactive interfaces when chat alone is not enough.
• Develop evaluation, observability, and feedback systems that measure whether V’s answers and actions are accurate, useful, efficient, and trustworthy.
• Establish primitives that make it easy for teams across Vercel to contribute new capabilities without creating fragmented agents or inconsistent user experiences.
• Help define what it means for a company to be operated through an agent and turn what we learn building V into ideas and infrastructure that can eventually benefit Vercel’s customers.

About Vercel:

Vercel is the agentic infrastructure company, freeing people and agents to ship what's next. For more than a decade we've helped builders move from idea to production with speed, security, and exceptional developer experience.

Now we're scaling our products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide.

What You Will Do:

• Design and build V as the primary agentic interface for getting work done across Vercel, from answering questions and analyzing data to executing complex, multi-system workflows.

• Build the agent architecture that allows V to understand intent, plan work, select the right skills and tools, recover from failures, and complete long-running tasks reliably.

• Ship polished experiences across Slack, web, and other surfaces, combining natural-language interaction with rich, interactive interfaces when chat alone is not enough.

• Develop evaluation, observability, and feedback systems that measure whether V’s answers and actions are accurate, useful, efficient, and trustworthy.

• Establish primitives that make it easy for teams across Vercel to contribute new capabilities without creating fragmented agents or inconsistent user experiences.

• Help define what it means for a company to be operated through an agent and turn what we learn building V into ideas and infrastructure that can eventually benefit Vercel’s customers.

About You:

• You have 7+ years of full-time software engineering experience and strong TypeScript proficiency.

• You are comfortable working across product surfaces and system boundaries, from conversational UI and interactive data experiences to APIs, queues, databases, permissions, and production infrastructure.

• You care about the quality of AI interactions: context selection, tool use, memory, latency, generated interfaces, uncertainty, and how the system communicates progress and asks for help.

• You have a track record of openness and adaptability. You have moved into unfamiliar technologies, domains, or responsibilities and learned quickly. This space is changing too quickly for fixed expertise to matter more than curiosity and judgment.

• Experience with using and building agent harnesses (OpenClaw, Hermes, Pi, etc) is a plus but not required

Benefits:

• Competitive compensation package, including equity.

• Inclusive Healthcare Package.

• Learn and Grow - we provide mentorship and send you to events that help you build your network and skills.

• Flexible Time Off.

• We will provide you the gear you need to do your role, and a WFH budget for you to outfit your space as needed.
