Applied AI Engineer, Marketing

Overview

At LangChain, our mission is to make intelligent agents ubiquitous. We help developers build mission-critical AI applications across the entire agent development lifecycle. Our open source frameworks LangChain and LangGraph see over 70+ million downloads per month. Developers rely on LangChain for composable integrations and LangGraph for controllable agent orchestration. Our commercial agent platform, consisting of LangSmith and LangGraph Platform, enables teams to build, test, run, and manage agents at scale across their organization.

Founded in 2023, LangChain powers top engineering teams at companies like Replit, Lovable, Clay, Klarna, LinkedIn, and more.

About the role :

We are looking for an Applied AI Engineer to join our Marketing Operations team. This is a hands-on role focused on building LangChain and LangGraph-powered agents that make our go-to-market teams more efficient. You’ll partner with Marketing Ops, Sales Ops, Growth and Data teams to design, prototype, and deploy agents that automate workflows, run analysis, and accelerate pipeline generation.

This role is ideal for someone excited to apply cutting-edge AI workflows to real-world business operations. It’s not a research role, we’re looking for a builder who can move quickly from prototype to production.

Design, prototype, and deploy agentic applications that automate workflows and deliver measurable business value.

Own projects end-to-end, from experimentation to production deployment, ensuring reliability and scalability.
