Software Engineer, Mid-Level to Staff+

About this role

About the RoleJoin 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 DoBuild 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 ForThree 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.
