Product Marketing - Agent Infrastructure

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 senior PMM to own go-to-market for LangSmith's infrastructure products: LangSmith Deployment, Sandboxes, and adjacent self-hosted and cloud infrastructure offerings. LangSmith Deployment gives teams the flexibility to run LangSmith in their own cloud or on-prem environment — meeting enterprise security, compliance, and data residency requirements. Sandboxes give developers safe, isolated environments to build and test agents without impacting production. You'll own messaging for a technically sophisticated audience, launch new capabilities in a fast-moving market, and build the enablement that helps our sales team win complex enterprise deals. WHAT YOU'LL DO: - Lead product launches. AI infrastructure moves fast, and we ship to match. You'll partner with product and GTM to launch new infrastructure capabilities and platform updates in ways that resonate with technical buyers and stand out in a crowded market. - Own positioning, messaging, and the infrastructure narrative for LangSmith Deployment, Sandboxes, and adjacent infra products. You'll shape how customers think about building, deploying, and scaling agents, and how we show up in the market, from the homepage to sales decks. - Build sales enablement that helps close enterprise deals. Our buyers are platform engineers, DevOps leads, and AI/ML infrastructure teams evaluating self-hosted and cloud deployment options. You'll create the talk tracks, use case briefs, battlecards, and objection handling the sales team needs. - Own competitive positioning. You'll stay close to the landscape and define differentiation that holds up to scrutiny in enterprise procurement conversations. - Partner on pricing and packaging for infrastructure products, bringing market and customer observations into decisions. - Create content that helps buyers move forward. Customer stories, web content, technical use cases: the materials that help champions make the case for LangSmith internally and help enterprise buyers clear procurement hurdles. - Feed the product roadmap. You'll synthesize customer conversations, win/loss signals, and competitive trends into clear feedback that helps our product and engineering teams decide what to build next. WHAT YOU'LL BRING: - You have 4-8+ years of product marketing experience. - You've owned positioning and messaging for a technical product or platform end-to-end — not just contributed to it. You've been the person accountable for the narrative, and you can point to results. - You've marketed developer tools, cloud infrastructure, DevOps platforms, or AI/ML infrastructure. You understand how infrastructure buyers evaluate build vs.
