## Description
**About the job
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.

We closed on a multimillion-dollar contract with a top lab and raised a $9m seed round led by Paradigm. We are now facing more lab demand for our data than we can currently serve.

Teaching AI superhuman capabilities is a responsibility we take very seriously. Our training data comes from work that is rigorous, ethically produced, and grounded in real expertise.

**About The Role**

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. In the era of AI-coding, systems-level thinking and attention to detail is more important than experience with a particular framework or language

**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

**Details**

- In-person in San Francisco 
- Competitive salary + meaningful equity 
- Free meals in office 
- Healthcare, 401(k), 15 days of PTO per year 
- Relocation assistance 
- Small, ambitious team 

This is an in-person role in San Francisco. We're a tight-knit founding team and we play to win. Join us if you like to win too.
