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 TEAM

The Customer Experience team helps customers adopt LangSmith and turn early momentum into lasting product usage. The team partners closely with GTM, Product, Engineering, and LangChain specialists to guide customers through onboarding, production readiness, and the practices required to build reliable AI applications.

ABOUT THE ROLE

We’re looking for an Activation Specialist to join the Customer Experience team. In this role, you’ll work with new customers during their first weeks on LangSmith, helping them move from signed contract to a working platform that is ready for agents in production. You’ll focus on activation milestones such as admin setup, user onboarding, traces flowing, evaluations in place, and customer teams feeling confident enough to keep building independently.

WHAT YOU’LL DO

  • Own customer onboarding from kickoff through early activation milestones, including admin setup, SDK integration, first traced run, first evaluation, and LangGraph deployment.
  • Guide customers through core LangSmith setup and production readiness topics, including security, org design, workload isolation, and integration questions.
  • Partner with GTM teams, Product, Engineering, and LangChain specialists to unblock customers and coordinate support when deeper expertise is needed.
  • Help customers build their first evaluation workflows, define what “good” looks like, and confirm they can debug a production trace independently.
  • Route customers to the right resources and turn recurring onboarding questions into runbooks, documentation, and repeatable processes.
  • Surface customer friction to Product and Engineering early and track activation metrics such as time to first trace, first evaluation, and production run.

WHAT YOU’LL BRING

  • 2–4 years of experience in a customer-facing role such as support, customer success, account management, onboarding, or a similar function.
  • A strong desire to work directly with customers and build productive, trusted relationships.
  • Excellent organization and follow-through, with a track record of keeping customers and internal partners aligned.
  • A proactive, industrious approach to learning new tools, solving problems, and rolling up your sleeves.
  • Clear, friendly written and verbal communication skills.
  • Curiosity about technology and AI, plus a willingness to get hands-on and learn technical concepts on the job.

NICE TO HAVE’S

  • Customer onboarding experience at a SaaS company.
  • Familiarity with enterprise readiness concepts such as SSO, SCIM, ABAC, and workload isolation.
  • Exposure to developer tools, observability, evaluations, or AI/LLM workflows.
  • Familiarity with analytics, BI tools or SQL.

Compensation Philosophy:

We offer competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks.

We are hiring for this role across a range of scope, and the compensation band reflects that. Your offer depends on what we learn about your impact, craft, leadership, and communication during the interview process. We will tell you early where you’re tracking and talk comp with you before offer stage. Team members in the EU, UK, and APAC receive locally competitive benefits aligned with regional norms and regulations.

BENEFITS

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