ABOUT THE ROLE

Join an AI software team building agents that carry out business tasks across users' tools and systems. This hands-on individual contributor role spans product, platform, and AI infrastructure, with scope shaped around your strengths and interests.

WHAT YOU'LL DO

Build user-facing experiences across web and mobile that make delegating work to agents clear, trustworthy, and easy to use.
Own product features from early exploration and prototyping through production launch.
Develop backend APIs and core services for accounts, workspaces, permissions, billing, payments, and analytics.
Build and operate connector, authentication, webhook, automation, and integration infrastructure.
Design and improve agent runtimes, context management, execution environments, model serving, and supporting infrastructure.
Take ownership of production systems, improving their correctness, security, reliability, and operational simplicity.

WHAT WE'RE LOOKING FOR

Three to 15 years of experience building and 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 services and infrastructure.
Strong computer science fundamentals and an undergraduate degree in computer science.
Technical breadth to work across product engineering, platform systems, or AI infrastructure.
Hands-on experience with GCP and Docker, including deploying services and debugging at the container and Linux level.
Experience building agent systems or AI infrastructure beyond simple integrations with model APIs; runtime, sandboxing, distributed systems, databases, or low-level systems experience is relevant.
Ability to clearly explain what you built, your technical decisions, and the tradeoffs involved.
Experience building a product or system from scratch in an early-stage environment is valued.

COMPENSATION & BENEFITS

Base salary is $225,000 to $425,000 annually. Visa sponsorship is available.
