Job description

At Primitive Labs our mission is to make human behavior a first-class primitive of software development.

As an intern at Primitive Labs, you will build at the frontier alongside the founding team, across both research and engineering. Your work could span agent architectures, evaluation systems, infrastructure, or applied research, wherever you are most driven to contribute. The goal is real ownership from day one: you ship, you learn fast, and your work makes it into what we are building. At Primitive Labs everyone is a builder: the whole team pushes code and contributes to research.

We hire for potential, and we base compensation on what we believe you can achieve rather than years of experience or a list of skills.

About Primitive Labs

Primitive Labs is building AI systems that are human-aligned. As machines make more of the decisions that shape our lives, we are working to keep people at the center of them.

Everyone at Primitive Labs is a builder. Our whole team pushes code and contributes to research. The best work, in our experience, comes from a few people trusted with real ownership and left to do it well, with no layers in between. We move quickly and speak honestly. We hold that every belief can be challenged, especially our own. We want people who are deeply passionate about their work and have a virtually unlimited intellectual curiosity. If you believe in building AI systems that are human-aligned and genuinely love solving hard problems, we would love to talk.

Primitive Labs AI Inc. is an equal opportunity employer.
