Job summary

Responsibilities

In this role you will build powerful tools that help product engineers iterate rapidly on the Agent experience and directly enhance the core Agent itself. You’ll bridge the gap between the AI team (working on the core Agent logic) and the UX team (crafting delightful Agent experiences), enabling…

• Build high-throughput backend applications and services, like streaming chat between user and agent.
• Design a collaborative "Multiplayer Computer" that lets humans and AI agents work together on shared shells, filesystems, and state—conflict-free and in real time.
• Develop infrastructure (frontend & backend) that empowers product engineers to rapidly ship delightful user experiences.
• Design and build durable, well-crafted interfaces between the Agent and internal systems, as well as external agentic systems (MCP)

What they're looking for

• 8+ years professional experience in building backend services, systems and platforms
• Someone who values simplicity and pragmatism—you think radically but ship incrementally.
• Self-directed and comfortable working autonomously.
• Collaborative and team-oriented with a strong sense of shared ownership.
• Experience across the full-stack.
