Senior Agent Runtime Engineer

We are reimagining the phone. AI phones need to be proactive, intuitive, intelligent and low cost. This is a mission critical for rest of the world to adopt intelligence.

There are over 5 billion people using everyday applications such as email, messaging, notes, tasks, and calendars, yet most are not AI-native. Our mission is to build proactive applications and devices that bring intelligence into daily conversations, coordination and workflows, with minimal prompting.

Focus: Building the actual execution infrastructure for AI agents.

• Implement agent runtime and orchestration components.

• Build tool-calling and execution interfaces.

• Support multi-step and long-running task execution.

• Manage task state, execution history and asynchronous workflows.

• Implement error handling, retries and recovery mechanisms.

• Integrate multiple model providers.

• Build observability and tracing for agent execution.

• Optimize latency, reliability and inference costs.

• Work with context and memory components to provide relevant information to agents.
