Product Marketing - LangSmith Fleet

San Francisco, CA$125,000 - $165,000

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 Product Marketing Manager to help drive go-to-market for LangSmith Fleet, our product for bringing agents to every team in an organization.

Fleet enables anyone to build, use, and manage agents with natural language — while giving organizations the security, observability, model flexibility, admin controls, and API extensibility they need to deploy agents responsibly across the business. It sits at the intersection of developer platform, enterprise SaaS, and end-user productivity.

This role will help shape how we take Fleet to market across both sales-led and product-led growth motions. You’ll work on positioning and messaging, product launches, content, enablement, campaigns, customer storytelling, and cross-functional programs in partnership with product, sales, education, and marketing.

The audience is broad and nuanced: technical buyers who care about security, observability, integrations, APIs, and governance; technical champions who want to extend and operationalize agents; and nontechnical users who need to understand what agents can do for their day-to-day work. You’ll help translate a rapidly evolving product into clear stories, content, and programs that drive awareness, adoption, and revenue.

What You’ll Do

Help launch new Fleet capabilities in a fast-moving market. You’ll partner with product and gtm to bring new features and use cases to market.
Develop positioning and messaging for Fleet. You’ll help define how Fleet shows up across the website, sales materials, launch assets, campaigns, product pages, and customer-facing content.
Create content that helps different audiences understand and adopt Fleet. This may include launch blogs, solution briefs, use case pages, customer stories, comparison pages, demo narratives, sales decks, guides, and campaign assets.
Build enablement for a sales-led motion. You’ll help equip sales and customer-facing teams with talk tracks, objection handling, discovery questions, demo narratives, competitive context, and materials that help them speak to technical buyers and business stakeholders.
Support PLG and adoption programs. Fleet is also a product businesses and users can try, build with, and adopt directly. You’ll help create onboarding, activation, lifecycle, and educational content that helps users understand what to build and how to get value.
Partner with demand generation on campaigns. You’ll help turn product narratives, use cases, launches, and customer insights into campaigns that drive pipeline and product adoption.
Stay close to customers and the market. You’ll synthesize customer conversations, sales feedback, product usage signals, competitive activity, and market trends into insights that improve our messaging, roadmap inputs, and GTM strategy.
Help define how Fleet fits into the broader LangSmith platform. You’ll connect the Fleet story to Observability, Evaluation, Deployment, Sandboxes, LangGraph, and the broader LangChain ecosystem.

What you’ll bring

You have 2–4+ years of product marketing, developer marketing, or solutions marketing experience.
You’ve worked on technical products, developer tools, AI/ML products, B2B SaaS, infrastructure, automation, or platform products.
You can translate technical concepts into clear, customer-facing messaging. You don’t need to be an engineer, but you should be comfortable learning technical products and asking good questions.
You’re excited by a product that serves multiple audiences: developers, technical buyers, operators, admins, and nontechnical end users.
You understand how sales-led and product-led motions can work together. You can create materials that help sales teams win while also helping self-serve users understand and adopt the product.
You write clearly and quickly. You can turn a product capability, customer problem, or technical workflow into a compelling piece of content or enablement.
You like working cross-functionally. You’ll partner closely with product, sales, demand gen, devrel, education, customer-facing teams, and the broader marketing team.
You’re comfortable with ambiguity and iteration. Fleet is evolving quickly, and the market for workplace agents is still being defined. You’re excited to ship, learn, and improve.
You have genuine curiosity about agents and how they will change how teams work.
You use AI tools in your own work and are interested in finding new ways to increase your effectiveness with them.

Nice to have

Experience marketing developer tools, AI products, automation products, productivity tools, or enterprise SaaS platforms.
Familiarity with the LLM, agent, or AI application development ecosystem.
Experience supporting both technical buyers and business/end-user audiences.
Experience partnering with sales on enterprise deals, including enablement, customer-facing storytelling, competitive support, or account-based campaigns.
Experience with PLG motions, onboarding, activation, lifecycle marketing, or self-serve adoption.

Why Join

You’ll help define a new category. Fleet is bringing agents from developer experiments into everyday work across companies.
You’ll work on a product with both end-user pull and enterprise depth. Fleet is easy to try, but also deeply connected to LangSmith’s security, observability, evaluation, deployment, and API capabilities.
Your work will directly shape how the market understands Fleet. This is a high-impact product area with room to influence messaging, launches, content, campaigns, and GTM strategy.
You’ll join a small, fast-moving team. You’ll get real scope, close access to product and GTM leaders, and the ability to ship meaningful work quickly.
Agents are where software is heading. LangChain is at the center of that shift, and you’ll help tell the story of how agents move from prototypes to real usage across companies.
