Key Responsibilities

Member of Technical Staff (Infrastructure)
On-site | Full-time
Compensation: $140K-$200K (CA$190K – CA$280K)

We are building the open-source browser infrastructure that powers the next generation of AI agents. With over 6,000 GitHub stars and millions of sessions served monthly, our platform grew 50x in 2025 alone. We provide the "eyes and ears" for AI, allowing developers to ship products that interact with the web seamlessly via our API.

As one of our first ten employees, you will join a high-performance, talent-dense team of four. We are backed by world-class investors and focused on solving the hardest problems in distributed systems, from kernel-level debugging to global VM orchestration.

The Role

As a Member of Technical Staff, you will build and scale the distributed systems that power millions of browser sessions. Browsers are notoriously resource-heavy; your mission is to make them fast, ephemeral, and globally accessible. You will work across the stack, but your primary focus will be on the core infrastructure that ensures sub-second startup times and robust multi-tenant isolation.
