Description

About the company

The company 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.

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.

You would be joining a close-knit team that has reached product market fit, and your work would directly help to multiply our revenue.

About the role

As a Software Engineer at the company, you’ll build the systems and infrastructure that our entire company relies on. You will solve open-ended, technical challenges with focus on performance, scale, and simplicity.

Examples of what you'll do

Design and build scaleable systems that generate RL environments

Create agentic QA systems to validate environment quality and fairness

Work directly with AI researchers at leading labs to understand what makes training data effective

Handle petabyte scale ETL and orchestrate millions of concurrent jobs

Support new product lines as we expand beyond coding environments

Manage our security posture and compliance requirements
