Job description

Collinear is a research-focused AI company building systems that make intelligent models more reliable, aligned, and useful in real-world settings. We work across post-training, RL, distillation, and evaluation to help teams get practical reasoning and behavior from open-source models. Our approach is grounded in technical rigor, clear thinking, and building tools that last.

How We Work

We operate with very little bureaucracy, which means decisions are made quickly and ideas move straight into action. Everyone has real ownership and is trusted to learn fast, ask questions, and figure out how to unblock themselves when the path is not obvious. We expect clear communication, thoughtful judgment, and a focus on impact rather than process. You will work closely with teammates who care deeply about the craft and the mission.

Who Thrives Here

People who enjoy solving hard problems, take initiative, and do not need hand holding tend to thrive at Collinear. If you like autonomy, fast decision cycles, and collaborating with others who hold a high bar for clarity and execution, you will feel at home here. This is a place for builders who want their work to matter and to be felt immediately.
