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

As a Software Engineer at idler, 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
What we’re looking for
1-10 years of experience writing excellent production software (new grads OK)
Experience with full-stack applications in a popular programming language
A meticulous problem solver who creates robust systems under time pressure
Tech stack
Typescript, React, NodeJS, Postgres, Redis, Vercel, Cursor/Claude Code/Codex, Tinker, Modal, AWS, Daytona, GRPO
