Software Engineer, Mid-Level to Staff+

About the Role

Join a team building an AI platform that helps businesses delegate work to agents across their tools and systems. This hands-on individual contributor role may focus on product, platform, or AI infrastructure, with opportunities to work across areas.

What You'll Do

• Build user-facing experiences across web and mobile, making agent workflows clear, reliable, and easy to use.

• Own product features from early exploration through production, incorporating customer feedback along the way.

• Develop backend APIs and services for accounts, permissions, billing, analytics, integrations, and automation.

• Design and operate production systems, improving their reliability, security, and simplicity.

• Build agent infrastructure such as execution harnesses, context management, sandboxed runtimes, and model-serving systems.

• Work across application architecture, data models, distributed systems, databases, and cloud infrastructure as needed.

What We're Looking For

• Three or more years of experience shipping production software, with recent hands-on individual contributor work.

• Production experience with TypeScript across Node.js backends and React frontends, plus ownership of backend or infrastructure work.

• Hands-on experience with GCP and Docker, including deploying services and debugging at the container or Linux level.

• Strong computer science fundamentals and a computer science undergraduate degree.

• Experience building core agent or runtime infrastructure, such as tool execution, sandboxed environments, agent harnesses, or model serving. Work limited to wrappers around model APIs is not a fit.

• Knowledge of systems such as databases, distributed systems, compilers, or operating system internals is valuable; Rust or C++ experience is a plus.

• Clear communication about systems personally built, design choices, and tradeoffs, along with the ability to work as a hands-on engineer across a range of product and infrastructure problems.
