Job description

About the role

You'll build the core agent infrastructure that powers Sana's mission to bring superintelligence to work. This is a greenfield opportunity to define how AI agents plan, reason, and execute across enterprise environments—building systems that reliably handle real-world complexity at scale. You'll work at the intersection of agent architecture, context-, tool- and prompt engineering, and production infrastructure.

In this role, you will

• Architect multi-step planning, orchestration, and tool routing for agents

• Implement code generation agents and sandboxed code execution

• Engineer memory, state, and context packing/grounding strategies

• Balance latency, quality, and cost controls for agent execution

• Develop safe fallbacks, graceful degradation and robust error handling

• Collaborate with platform and search teams to deliver reusable agent infrastructure

• Establish safety guarantees and measurable quality improvements

What success looks like

• Agent architectures are robust, reliable, and enterprise-ready

• Context and tool engineering enables agents to act intelligently, at scale

• Clear metrics, automated evaluation, and continuous improvement in agent capabilities

• Quality and safety are measurable and continuously improving

• Durable building blocks accelerate product teams and unlock new capabilities
