Reinforcement learning environments for AI coding models

idler Raises $9M in Seed Funding

Software Engineer

Idler builds reinforcement learning environments that teach AI models to code like 0.01% engineers, using real-world coding scenarios encountered by frontier models. The Software Engineer will build features and tooling for agentic systems that create and QA coding environments, including UI components, backend services, and automated testing workflows, while collaborating with engineers and AI researchers.

Idler builds reinforcement learning environments that teach AI models to code like 0.01% engineers. They are seeking a Software Engineer to build features and tooling for their agentic systems, working closely with senior engineers and the founding team.

Research Scientist

idler is a frontier data research lab that builds evaluations and environments for measuring and training AI models. The Research Scientist will measure and improve how models learn from tasks, collaborate with frontier-lab researchers, validate data quality, and create new datasets and data products.

Design Engineer

idler is a frontier data research lab that builds evaluations and environments for leading frontier labs to measure and train their models. The Design Engineer will own the user experience for customers and the internal team by building robust, performant applications and creating intuitive interfaces for complex reinforcement learning environments.

Create Your Own Role

idler is a frontier data research lab that builds evaluations and environments for measuring and training advanced AI models. The role is open-ended, allowing candidates to propose how their distinctive skillset can help accelerate the team’s work developing reinforcement learning environments and teaching machines to think.

Problem Design Engineer

The Widget Factory is the quality assurance division of Idler, focused on ensuring coding problems meet research-grade standards for AI training. The role involves reviewing code changes, assessing problem fairness, and writing justifications for assessments, all while working asynchronously and flexibly.

Widget Factory Ambassador

Widget Factory is a special division of Idler focused on quality, seeking Campus Ambassadors to help build a team reviewing coding datasets for AI systems. The role involves connecting peers with flexible technical work while developing recruiting skills.
