Sales Development Representative (London) - EMEA

Overview

LangChain builds tools for agent engineering, with open-source frameworks including LangChain and LangGraph and a platform, LangSmith, for building, evaluating, deploying and operating AI agents. It has raised 125 million dollars at Series B from investors including IVP, Sequoia, Benchmark, CapitalG and Sapphire Ventures, reports more than 6,000 active LangSmith customers, and says five of the Fortune 10 use LangSmith in production. The company is hiring a full-time Sales Development Representative for EMEA, based in London, United Kingdom.

The SDR joins a team that turns strong inbound interest and targeted outbound demand into qualified opportunities and creates a good first experience for prospects. The person works with Marketing, Sales and Operations and uses LangChain and LangGraph-powered agents to automate list building, enrichment and outreach, leaving more time for conversations with teams exploring agentic AI. The role aims to drive pipeline and revenue while learning to use AI and automation as a next-generation go-to-market operator.

Responsibilities include following up with inbound and outbound prospects by phone, email and LinkedIn to establish fit and needs, handing qualified opportunities to Account Executives, sharing insights from conversations to inform sales plays, product roadmap and agent development, experimenting with new channels, messaging and automation to improve conversion, and using LangChain-powered agents to test and refine prospecting.
