About LangChain

At LangChain, our mission is to make intelligent agents ubiquitous. We build the foundation for agent engineering in the real world, helping developers move from prototypes to production-ready AI agents that teams can rely on. We began as widely adopted open-source tools and have grown to also offer a platform for building, evaluating, deploying, and operating agents at scale.

With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we’re in a stage where we’re continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together. LangChain is a place where your contributions can shape how this technology shows up in the real world.

Today, our platform includes LangSmith (Observability, Evaluation, Deployment, Fleet, and Sandboxes), our open source frameworks (LangChain, LangGraph, and Deep Agents), and the newly launched LangSmith Engine for autonomous agent improvement. We have 100M+ monthly open source downloads, 6,000+ active LangSmith customers, and 5 of the Fortune 10 use LangSmith in production (+35% of the Fortune 500 overall), including teams at Klarna, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, LinkedIn, Monday.com, Nvidia, and Bridgewater.

About the Role

We’re hiring Sales Development Representatives to join our SDR team and help shape the future of how companies adopt LangChain. As part of our SDR team, you’ll turn high inbound interest and targeted outbound demand into qualified opportunities and create an exceptional first-touch experience for prospects.

You’ll work closely with Marketing, Sales, and Operations, and use LangChain and LangGraph-powered agents to automate list building, enrichment, and outreach—freeing you to focus on high-impact prospecting and conversations with teams exploring agentic AI.

What makes this role different: You’ll drive pipeline and revenue while learning to leverage AI, automation, and LangChain itself to become a next-generation GTM operator.

What You Will Do

  • Follow up with inbound and outbound prospects via phone, email, and LinkedIn to uncover fit, needs, and potential value.
  • Partner closely with Account Executives to hand off qualified opportunities and ensure a smooth buyer experience.
  • Capture and share insights from conversations to inform sales plays, product roadmap, and agent development.
  • Experiment with new channels, messaging, and automation to continuously increase conversion and efficiency.
  • Use LangChain-powered agents to test, learn, and improve prospecting strategies.

How to Be Successful in This Role

  • 1–2 years of experience in a Sales, SDR, or BDR role within SaaS or technology (or strong curiosity and drive if you’re early in your career).
  • Clear, confident communicator who can engage both technical and business audiences.
  • Motivated by learning, iteration, and experimentation—you treat outreach like a craft.
  • Comfortable with a mix of structure and ambiguity—you can execute repeatable processes while improving them along the way.
  • Excited about modern sales tech, AI tools, and shaping how next-generation GTM teams operate.
  • Positive, persistent, and highly organized—you follow up, follow through, and bring energy to every interaction.
  • C2-level French or German (Common European Framework), or native speaker equivalent, is required for this role.

Compensation & Benefits

  • Compensation: Competitive compensation including base salary, meaningful equity, and benefits such as health and dental coverage, flexible vacation, a 401(k) plan, and life insurance. Actual compensation varies based on role, level, and location. For team members in the EU and UK, benefits are locally competitive and aligned with regional norms and regulations.

  • Annual On Target Earnings: 110,000 GBP (70/30 split)

Benefits

Benefits include medical, dental, and vision coverage, flexible vacation, a 401(k) plan, meals on in-office days in the US, and more.
