Staff Software Engineer (Backend)

Location: San Francisco, New York, or Remote (US)

On-site/Remote| Full-time

Compensation: $225K – $300K 

We aren't building another chatbot or a "copilot" to sit on a sidebar. We are building the next generation of the workforce: Autonomous AI Employees.

Our flagship product is an AI Business Development Representative (BDR) that doesn't just assist a sales team—it joins it. She researches leads, manages her own deliverability infrastructure, handles objections, and books meetings autonomously. With over $8M ARR, $35M+ in funding (including Y Combinator), and a rapidly growing customer base, we are now tackling the engineering mountain of "Ava 2.0." We are looking for foundational engineers to build the backend orchestration that makes autonomous digital workers a reality.

The Role

As a Staff Software Backend Engineer, you will build the engine that allows AI employees to think, act, and evolve. This is a high-leverage role where you will own major portions of a platform that replaces an entire enterprise sales stack—including CRM, lead databases, and campaign engines—within a single product.

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.
