Senior AI Developer at eClerx in New York, New York, United States

Job description

• We are seeking a Senior AI Developer to support one of our premier clients—a leading global financial institution—with strong expertise in building intelligent AI agents and components that can reason, plan, and act autonomously. The ideal candidate will have hands-on experience developing scalable multi-agent AI systems using modern orchestration frameworks such as LangChain and LangGraph, integrating agentic workflows end-to-end, and shipping production-grade AI applications.

Responsibilities

• Design and develop AI agents and autonomous multi-agent systems using modern agentic frameworks including LangGraph and LangChain, with the ability to architect agent graphs, define node transitions, and manage stateful agent workflows
• Build and orchestrate multi-agent pipelines—including supervisor agents, collaborative agent networks, and hierarchical agent architectures—to solve complex, multi-step financial use cases
• Implement guardrails, reasoning workflows, and ReAct-based patterns within LangChain/LangGraph to improve reliability, decision-making, and agent safety
• Develop memory management (short-term, long-term, episodic) and tool-use capabilities (MCP, LangChain Tools, custom tool integrations) for AI agent systems
• Leverage LangGraph's stateful graph execution model to build resilient, interruptible, and human-in-the-loop agentic workflows
• Integrate LLM-powered agents with external APIs, databases, and enterprise data platforms via LangChain's retrieval, routing, and chain composition primitives
• Partner closely with prompt engineers, data scientists, and platform teams to optimize AI application performance across multi-agent deployments
• Build and maintain scalable Python-based services, APIs, and microservices that serve as agent execution environments and tool backends
• Develop and support AIOps capabilities and CI/CD pipelines for AI agent deployment, versioning, and monitoring (including LangSmith or equivalent observability tooling)
• Work with modern data platforms including Snowflake, Databricks, and Lakehouse architectures as grounding and tool-use data sources for agents
• Ensure AI agent solutions are scalable, secure, observable, and production-ready

Requirements

• 8+ years of overall software engineering experience, with a strong focus on AI/ML systems in recent years
• Hands-on production experience with LangChain — including chains, agents, tools, retrievers, memory modules, and prompt templates
• Hands-on production experience with LangGraph — including stateful graph construction, conditional edges, checkpointing, human-in-the-loop interrupts, and multi-agent graph topologies
• Demonstrated experience designing and deploying multi-agent systems — including orchestrator/worker patterns, agent-to-agent communication, task delegation, and shared state management
• Experience implementing guardrails, ReAct patterns, and chain-of-thought reasoning within agentic pipelines
• Strong understanding of agent memory architectures (in-context, vector-store-backed, episodic) and tool-use patterns (function calling, MCP, LangChain tool wrappers)
• Familiarity with LangSmith or equivalent observability/tracing platforms for debugging and monitoring agent behaviour in production
• Strong Python engineering skills including async programming, APIs, and microservices
• Experience with AIOps and CI/CD pipeline development for AI agent deployment and lifecycle management
• Hands-on experience with Snowflake, Databricks, and Lakehouse architectures
• Strong understanding of scalable distributed systems and cloud-native application development
• Strong communication and cross-functional collaboration skills
• Experience with other agentic frameworks such as AutoGen, CrewAI, or OpenAI Assistants API
• Familiarity with LangGraph Cloud or self-hosted LangGraph Server for agent deployment
• Background in financial services AI applications (risk, compliance, trading, operations)
• Experience with vector databases (Pinecone, Weaviate, pgvector) as long-term memory stores for agents
• Contributions to open-source LangChain/LangGraph ecosystem
