Job description

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 Growth & Monetization team focuses on how developers discover, adopt, and scale with LangChain's products. We work across the full stack to improve onboarding, activation, and usage while building the systems that power billing, pricing, and monetization. This team partners closely with product, design, and go-to-market teams to understand developer behavior and translate those insights into product improvements that drive adoption and revenue. Our work directly shapes how developers and organizations move from experimentation to production on the LangChain platform.
About the role
LangChain is hiring a Senior Fullstack Engineer to build the foundational product features and integrations that power user acquisition, rapid experimentation, and self-serve expansion. This is a high-impact 0→1 role on a newly formed team responsible for building growth systems from the ground up. You'll work closely with product, design, GTM, and analytics to streamline activation, optimize packaging, and deliver a seamless growth story for developers and enterprise customers alike. This role will be in person 5 days/week in New York City, San Francisco, or Boston.
What you'll do
  • Work across our stack (React, TypeScript, Python, Go) to deliver full-stack product features that drive growth and retention
  • Build flexible experimentation systems and processes capable of targeting diverse growth metrics
  • Participate in data-driven, rapid growth experiments across the user funnel from onboarding to monetization
  • Design and ship new onboarding features and improvements that accelerate time to value
  • Build growth levers including usage-based guardrails, smart upgrade triggers, and contextual CTAs
  • Collaborate closely with product, design, GTM, and analytics teams to identify, prioritize, and execute high-impact growth opportunities

What you'll bring
  • Extensive fullstack software development experience using React, TypeScript, and Go and/or Python
  • Strong product intuition and a track record of working on monetization, pricing, or activation features
  • Familiarity with usage metering, subscriptions, and internal tooling for pricing experiments
  • Comfortable working with REST APIs, Postgres, Redis, and modern backend infra
  • Startup DNA with the ability to thrive in fast-paced, zero-to-one environments
  • Self-directed with an ownership mindset
  • Bonus: Experience building for developers or product-led growth platforms
  • Bonus: Familiarity with LLMs, GenAI applications, or agentic frameworks

Compensation
  • Salary Range: $175,000-$240,000 USD

Compensation Philosophy:
We offer competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks. Actual compensation and offerings will vary based on role, level, and location. 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.
