# Research Engineer

About idler idler is a frontier data research lab. We build the evals and environments that the world's leading frontier labs use to measure and train their models. After raising a $9m seed round led by Paradigm, we spent the last year developing coding evals for top coding models you know and love. At the same time, we've expanded into other domains besides coding: RSI & Auto-Research, Law, Enterprise Business, Cybersecurity, and others. Now, we are facing more lab demand for our data than we can serve, and are rapidly scaling the team to grow the business. Our approach to creating training data scales using technology, and all of our data products are built on a unified self-reinforcing platform that learns through experience.
