Langchain Engineer

LangChain Engineer - Mid to Senior Level

Remote | Contract-to-Hire

About the Role

We are looking for a mid-to-senior level LangChain Engineer to join a growing AI engineering team building production-grade applications powered by large language models (LLMs).

In this role, you’ll work closely with engineers and technical stakeholders to design, develop, and optimize AI-powered applications and agentic workflows. The ideal candidate has strong Python experience, hands-on experience with LangChain or similar LLM frameworks, and experience deploying applications in a major cloud environment.

This is an excellent opportunity for an engineer who enjoys working at the intersection of software engineering, AI, and emerging LLM technologies and wants to have a meaningful impact on a growing team.

What You'll Do

• Design and develop production-grade AI/LLM applications using LangChain and related frameworks

• Build and integrate LLM-powered workflows, agents, and applications

• Develop scalable backend services and APIs using Python

• Integrate LLMs with external data sources, APIs, tools, and enterprise systems

• Develop solutions involving prompt engineering, retrieval-augmented generation (RAG), tool calling, and AI agents

• Deploy and maintain AI applications within a major cloud environment

• Collaborate with engineers, product stakeholders, and clients to translate business requirements into technical solutions

• Evaluate emerging AI/LLM technologies and identify opportunities to improve existing solutions

• Write clean, maintainable, well-tested code suitable for production environments

• Troubleshoot, optimize, and improve the performance, reliability, and scalability of AI applications

What We're Looking For

• Mid-to-senior level software engineering experience

• Strong proficiency in Python

• Hands-on experience with LangChain or comparable LLM/AI application frameworks

• Experience working with at least one major cloud platform:

  • AWS

  • Google Cloud Platform (GCP)

  • Microsoft Azure

• Strong understanding of software engineering fundamentals, APIs, and application development

• Experience building or integrating LLM-powered applications

• Ability to work independently in a remote environment while collaborating effectively with a distributed team

Nice to Have

• Experience with LangGraph

• Experience building AI agents or agentic workflows

• Experience with RAG, vector databases, embeddings, and semantic search

• Familiarity with OpenAI, Anthropic, Gemini, or other foundation models

• Experience with Docker and/or Kubernetes

• Experience with CI/CD and production cloud deployments

• TypeScript experience

• Experience working in a consulting or client-facing environment

Education

A Bachelor's degree is not required if the candidate has strong relevant experience. Master's or PhD graduates with relevant hands-on experience in AI, machine learning, computer science, or a related field are encouraged to apply.

This role is not intended for candidates coming directly from an undergraduate program without professional or substantial project experience.
