Stamp is the AI Native Email Client. It automatically filters, prioritizes, and composes your emails for you, so you don't have to.

Email was built to make us more productive, not less. Stamp is the first email solution to deliver on that promise.

About Stamp

We believe that Human Intelligence is the most valuable currency – one that should only be spent on solving the most challenging and important problems.

That’s why we’re building Stamp, the first AI Secretary. Stamp handles your emails and calendar for you, even when you’re not using it, so you can focus on the problems that matter most.

Stamp is the first product of its kind, capable of handling complex user workflows (drafting emails, searching the web, cleaning up mailboxes) via its Agent when a user is online, while also automatically summarizing, categorizing, and drafting replies to emails while a user is offline.

We’re a rapidly growing, fast moving company, with single minded focus on elevating our users’ productivity through cutting edge technology.

About the Role

As a founding full stack engineer, you’ll be working in several areas, helping improve Stamp’s web frontend, backend services, and machine learning models.

Moreover, you’ll have the opportunity to:

• Own the product experience and UX, helping improve Stamp’s core features and capabilities
• Implement deep technical optimizations to improve performance and model accuracy
• Work with mail protocols, advanced machine learning training pipelines, agentic workflows, and more!

We’re looking for engineers who:

• Have direct experience building full stack AI applications
• Love agonizing over every part of the user experience and highly optimizing the code they write
• Have experience architecting large scale systems (having worked with email protocols is a plus!)

Job Requirements

• Significant experience working with Next.js, Express, and FastAPI/Flask
• Experience building accurate agentic systems
• Experience building full stack applications from scratch
• US Citizen, able to work in person in San Francisco

Node.js, TypeScript, FastAPI, Python, Next.js, React, MongoDB

Stamp is a standalone email client, so we also work deeply with the SMTP and IMAP protocols.
