The Product Engineer will own the browser interaction product, working closely with the CEO and team to enhance the product's capabilities for AI agents.
Responsibilities
- Own the browser interaction product end-to-end, including prompt-based interactions, persistent profiles, session chaining, and scrape-then-interact workflows
- Build developer-facing APIs using TypeScript, Node.js, Playwright, Puppeteer, browser-use, Stagehand, Chromium, and related tools
- Improve reliability across arbitrary web pages, login flows, forms, changing DOMs, stateful sessions, and real-world browser edge cases
- Talk directly with developers through GitHub, Discord, customer conversations, and product feedback loops
- Dogfood the API relentlessly and improve latency, response shapes, error messages, docs, and overall developer experience
- Make product decisions without a PM or designer, including what to build, what to skip, what to kill, and what to ship quickly
