Founding Engineer at YC-backed enterprise browser automation startup

You will build the core infrastructure for an on-device browser agent that automates mission-critical workflows without APIs. Working across the full stack, you will develop a robust automation engine and secure environment used by global enterprises for identity management and security enforcement, defending against state-sponsored threats in real-time.

• Scale and improve the core browser automation engine to handle complex web-based tasks and autonomous user provisioning.
• Develop and secure the on-device desktop environment using Electron to ensure reliable performance across macOS, Windows, and Linux.
• Partner directly with customers at decacorn scale-ups to diagnose challenges, design features, and ship production solutions within single-week cycles.

• At least 1 year of production software experience with a proven ability to ship high-quality features from concept to production independently.
• Deep technical curiosity and strong systems-thinking skills required to debug messy web automations and end-to-end encrypted environments.
• Proficiency in TypeScript and Postgres, with a strong desire to master Electron, browser extensions, and tools like Puppeteer or Selenium.

• Work at the frontier of "browser-using agents" in a high-stakes enterprise environment where your code secures mission-critical corporate bank accounts and SaaS tools.
• Join an elite engineering culture of Cambridge and Imperial alumni with backgrounds at TikTok, operating as a high-caliber team of four with zero bureaucracy.
• Exceptional growth potential with founding-team equity and a pathway to relocate to the San Francisco office with full US visa sponsorship if desired.
