Building the runtime infrastructure that powers Moveworks' AI agents — the systems that orchestrate, execute, and deliver agent responses to millions of enterprise users in real time. This role sits where large language models meet distributed systems.

Responsibilities

Agent orchestration engine — A state machine that manages long-running agent sessions, coordinating planning, execution, and user interaction across multiple LLM calls and tool invocations
Model routing and adaptation — Choose, route between, and fine-tune or distill LLMs for specific agent tasks
Distributed session management — Lease-based ownership using conditional writes, heartbeat protocols, and crash recovery via checkpointing
Event-driven message pipeline — FIFO queues for ordered delivery, consumers for event processing, and real-time streaming via gRPC and Socket.IO
Structured concurrency — Running multiple concurrent tasks per session with fail-fast semantics and graceful cancellation

Requirements

Nice to have: Python asyncio
Nice to have: Go goroutines
Nice to have: SQS
