Mechanize, Inc.

We build environments and evals for frontier coding agents. In these environments, models carry out software engineering work such as building a feature, deploying an application, or debugging an issue in an unfamiliar codebase. A grader scores the model’s performance, and these scores serve as signals during reinforcement learning and evaluations.

Careers

We’re hiring software engineers to design and build these environments. Apply here.
