Deployed Engineer

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, LangChain, LangGraph, LangSmith, and Fleet are used by teams shipping real AI products across startups and large enterprises. Millions of developers trust LangChain to power AI teams at companies like Replit, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, and 35% of the Fortune 500.

- Own the technical win in pre-sales by designing POCs, answering deep technical questions, and guiding evaluations

- Help customers deploy and operate agent-based applications such as conversational agents, research agents, and multi-step workflows

- Advise customers post-sale on architecture, best practices, and roadmap-level decisions

- Run technical demos, trainings, and workshops for developer audiences

- Surface field feedback and contribute reusable patterns, cookbooks, and example code that...
