The Role

We're looking for an exceptional engineer to shape how AI agents interact with the web by building the open-source frameworks/demos and shaping the developer experience that makes Steel indispensable for AI developers.

Sample projects include...

• Building developer tools to run browser agents on top of Steel's Sessions API

• Running experiments to learn which models/prompts/harnesses actually work for browser automation

• Building eval sets to rigorously benchmark agents against real-world scenarios

• Creating open-source demos that show what's possible with AI agents and browsers

• Working with customers to help them deploy custom agents into their workflows

• Writing a technical post unpacking learnings from a 2-day debugging session

Requirements:

• 4+ years writing high-quality, production code

• AI-native - a heavy user of AI agents in day-to-day coding workflows

• Experience shipping full-stack product features end-to-end and enjoy moving between design, frontend, backend, and model integration

• Interest in developer tooling and opinions about developer ergonomics

• Strong communication skills with comfort writing technical content

• Strong product sense

• Thrive in highly autonomous work environments

Applying

If there appears to be a fit, we'll reach out to schedule 2-3 short technicals. After, we'll schedule an on-site in our office, where you'll work on a small project, discuss ideas, and meet the team.
