Senior Python / LangGraph Engineer

Quick Facts

• Role: Senior Python / LangGraph Engineer

Description

Join the effort to build a production-grade, cloud-native Enterprise Agent Development Platform that standardizes AI agent development and orchestration at scale using LangGraph. You’ll design LangGraph nodes, edges, and graphs, implement checkpointing, and create human-in-the-loop workflows. You’ll also ensure reliable orchestration behavior with retry/timeout/fallback patterns and add OpenTelemetry tracing for end-to-end observability.

Responsibilities

• Design and implement Python-based LangGraph nodes, edges, and graphs for agent orchestration

• Build checkpointing mechanisms using SQLite, Redis, and Postgres checkpointers

• Develop human-in-the-loop (HITL) workflows for controlled decision points

• Implement retry, timeout, and fallback patterns to improve orchestration reliability

• Integrate OpenTelemetry tracing across orchestration steps

• Collaborate to standardize LangGraph orchestration practices

• Improve reliability and scalability of agent workflows on AWS AgentCore Runtime

• Evolve the platform’s single-file developer experience for agent builders

Requirements

• 5+ years of Python development

• Expertise in LangGraph or LangChain agent orchestration

• Proficiency in async Python (asyncio)

• Skills in Python-based LangGraph node, edge, and graph construction

• Familiarity with checkpointing approaches using SQLite, Redis, and Postgres checkpointers

• Background in HITL workflow implementation

• Knowledge of retry, timeout, and fallback patterns in LangGraph

• Understanding of OpenTelemetry tracing across orchestration steps
