The Staff Software Engineer role will help develop the runtime infrastructure for Moveworks agent systems within ServiceNow. The position emphasizes distributed systems engineering for agent orchestration, session management, event-driven pipelines, structured concurrency, and production-grade observability and caching.
Key Responsibilities
- Agent orchestration engine: build a state machine that manages long-running agent sessions, coordinating planning, execution, and user interaction across multiple LLM calls and tool invocations.
- Distributed session management: implement lease-based ownership using DynamoDB conditional writes, heartbeat protocols for liveness, and crash recovery through checkpointing.
- Event-driven message pipeline: design ordered delivery and processing with SQS FIFO queues, handle event processing with Kafka consumers, and support real-time streaming via gRPC and Socket.IO.
- Structured concurrency: use Python asyncio TaskGroups to run multiple concurrent tasks per session, including message polling, lease heartbeats, output publishing, and orchestrator execution. Apply fail-fast semantics and graceful cancellation.
- Observability infrastructure: deliver OpenTelemetry instrumentation with distributed trace context propagation across async boundaries, including custom span lifecycle management for sessions that span minutes.
- Caching and state layers: build caching and persistent state using Redis and DynamoDB KV stores with per-org and per-bot scoping, batch read optimization, and hot-reload configuration.
Required Qualifications
- Deep experience in at least 3 of the following areas: distributed systems consistency models, idempotency, exactly-once delivery, distributed locking/leasing.
- Deep experience in at least 3 of the following areas: concurrent or async programming (Python asyncio, Go goroutines, structured concurrency, cancellation handling).
- Deep experience in at least 3 of the following areas: event-driven architectures (SQS, Kafka, pub/sub, backpressure, delivery guarantees).
- Deep experience in at least 3 of the following areas: database systems for infrastructure (DynamoDB conditional writes and transactions; Redis connection pooling and pub/sub).
- Deep experience in at least 3 of the following areas: observability (OpenTelemetry, distributed tracing, span context propagation, Prometheus metrics).
- Deep experience in at least 3 of the following areas: gRPC/protobuf (streaming RPCs, service interface design, error handling patterns).
- Strong in Python or Go (ideally both).
- Experience designing and operating systems that handle real traffic at scale.
- Comfort with ambiguity for novel problems without textbook solutions.
