Customer Marketing Manager

ABOUT US 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 at 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 looking for a Customer Marketing Manager to own how our customers' stories show up in the market. Our customers are building some of the most interesting agent systems in production today — and the best version of our marketing is them, in their own words, talking about what they built and why it matters. You'll own the full customer storytelling motion end-to-end: sourcing the right customers, running the interviews, producing the case studies, videos, and talks, and turning those stories into assets that move pipeline, close deals, and shape the narrative around agent engineering. You'll also build the programs that sit underneath the stories — references, advocacy, customer councils, launch participation — so that by the time we need a customer voice for a launch, an analyst briefing, or an enterprise deal, we already have the right relationships in place. This is a builder role. We have remarkable customer logos and real production stories to tell, but the customer marketing function itself is early. You'll help define what it looks like at LangChain. WHAT YOU’LL DO: - Own the customer story pipeline end-to-end. Source customers, run the interviews, draft the narrative, and ship in multiple formats, including written case studies, videos, executive spotlights, conference talks, and podcasts. - Build the reference and advocacy programs. You’ll equip sales with a relevant reference for any deal, and our best customers with a clear path to speak, write, and represent LangChain in the market. - Get customers into our biggest moments. Product launches, events, analyst briefings, keynote stages, and press moments. You'll work with PMM to identify which customers belong in which moments, and you'll handle activation end-to-end. - Turn customer stories into pipeline. Partner with sales to use customer stories where they can move deals, including talk tracks, account-specific reference matches, customer-led webinars, and proof points that help technical champions sell internally. - Partner with field and community marketing to develop customer events and programs that build community. Founder dinners, customer roundtables, executive meetups, and hands-on workshops with our most engaged builders. - Build the voice-of-customer feedback loop. Synthesize what you hear in customer conversations into clear input for product, PMM, and comms. You'll be one of the people in the company who hears the most directly from the people building on us. - Measure what matters. Customer-influenced pipeline, references delivered, stories produced, advocacy participation. Build the muscle for measuring this from the start. WHAT YOU’LL BRING
