Software Engineering Intern (Summer 2026)

About Promptless

When most people want to use AI for work, they don’t want to build prompt libraries, engineer context windows, or decide between different foundation models—they just want solutions that integrate with the tools they’re already using and fit directly into their existing workflows. At Promptless, we’re building AI teammates that combine context-aware agents and embedded user experiences to deliver AI products that are accessible to everyone.

We’re starting with an AI teammate that automatically updates customer-facing docs, like tutorials, API references, and support centers. We were one of the top companies in the W25 batch by revenue, and our product is already used by both startups and Fortune 500 enterprises, and we’re struggling to keep up with the demand for our product.

Our small founding team has led teams at fast-growing startups, published LLM research, competed in national and international olympiads (including the IMO), and graduated from top schools like Stanford, Yale, and Harvard.

About the role

At Promptless, everyone on the team (including interns!) works on the most critical problems at the company. Even as a Summer Intern, on a typical day you can expect to be talking to customers, working with founders to design and implement features that solve customers’ problems, shipping code, and seeing customers use the features that you just built.

For a full-stack role, we expect great candidates to have experience shipping production code used by real users and be comfortable across the entire stack, working on our React frontend Python/Flask backend, API integrations, and our kubernetes infrastructure. Bonus points if you have built LLMs or agents or have contributed to open-source AI projects.

Join us in San Francisco for an incredible summer!

You’ll chat with me (Prithvi), demonstrate your technical skills with one of our engineers, and join the team.
