Senior LangGraph Developer

Job Title: Senior LangGraph Developer
Locations: Dallas, TX | Charlotte, NC

Duration: 12 Months

Job Summary

The Senior LangGraph Developer will architect and implement production-grade, stateful multi-agent workflows using LangGraph to power intelligent, adaptive applications. This elite technical role demands deep expertise in LLM orchestration, agentic system design, and graph-based computation, with strong preference for candidates experienced with Google Agent Development Kit (ADK).

Key Responsibilities

LangGraph Architecture & Development

• Design and implement complex LangGraph workflows with advanced node logic, conditional branching, cycles, and persistent memory management for stateful agent interactions.
• Lead development of multi-agent systems that reason, collaborate, and adapt dynamically using LLMs for complex decision-making and automation.
• Optimize performance and scalability of LangGraph graphs for production workloads, implementing caching, streaming, and efficient state persistence.

Integration & Orchestration

• Integrate LangGraph with external APIs, databases, vector stores, and LLMs (OpenAI, Anthropic, Google, etc.) to create seamless intelligent pipelines.
• Build resilient error handling, retry logic, and fallback mechanisms for production-grade agent reliability.

Technical Leadership

• Mentor junior developers and establish LangGraph best practices, patterns, and code standards for the organization.
• Collaborate with AI researchers, data scientists, and product teams to translate research concepts into robust, production-ready implementations.
• Lead code reviews, architecture discussions, and technical design for agentic systems.

Production Operations

• Implement monitoring, logging, and observability for LangGraph workflows in production environments.
• Use LangGraph Studio and visualization tools for workflow debugging, optimization, and stakeholder demonstrations.

Required Skills & Experience

Core Technical Expertise

• 8+ years software engineering experience, including 3-4+ years building production LangGraph or agentic frameworks.
• Expert Python with advanced async/await patterns, graph algorithms, and state management.
• Deep understanding of LLM orchestration patterns (chain-of-thought, tool calling, memory, agent loops).
• Proven experience building stateful, multi-agent systems with fault tolerance and human-in-the-loop capabilities.

Framework & Platform Experience

• LangGraph mastery (nodes, edges, state, checkpoints, persistence, cycles, branching).
• Strong LangChain experience and familiarity with OpenAI, Anthropic, Google Vertex AI APIs.
• Google Agent Development Kit (ADK) experience strongly preferred.

Production Skills

• Experience with workflow debugging, graph visualization, LangGraph Studio.
• Production deployment experience (Docker, Kubernetes, serverless, cloud platforms).
• Expertise in GenAI observability (tracing, evaluation, monitoring agent performance).

Preferred Qualifications

• Experience building agentic RAG systems combining LangGraph with vector databases and retrieval.
• Familiarity with multi-modal agents handling text, images, structured data.
• Track record shipping production GenAI applications at scale.
• Contributions to open-source LangChain/LangGraph projects or GenAI community.
