About this Opportunity

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 Design Engineer at idler, you'll own the user experience for our customers and internal team. You'll be tasked with producing robust, performant applications that are a delight to view and use. Our RL environments are novel, complex artifacts that need to be easy to interact with and communicated well. You'll need a founder’s high-level thinking, a designer's taste, and an engineer's precision to succeed.

Examples of what you’ll do

Create a unified UI, layout and UX paradigm for inspecting and interacting with our RL environments that serves frontier labs and our internal team

Build a standard library and templates for our marketing materials that are beautiful and compliant with design best practices

About idler Idler builds reinforcement learning environments that teach AI models to code like 0.01% engineers. Our training environments are based on real-world coding scenarios that frontier models will actually encounter.

We've closed a multimillion-dollar contract with a leading foundation lab (the largest they've issued to date), and demand is outpacing our capacity to deliver. We're scaling fast to build the training data layer for frontier AI. Every breakthrough model will need environments like ours to learn real-world skills at scale.

We're a tight-knit founding team in San Francisco. We move quickly, think deeply about what makes good training data, and play to win. Join us if you want to win too.
