LangChain is seeking an experienced Enterprise Account Executive to join its growing go-to-market team in Philadelphia. You will own the full sales cycle for LangChain's AI agent platform, working with technical teams at enterprise companies to help them discover, evaluate, and adopt LangSmith and related products. In this high-impact role, you'll act as a trusted advisor to prospects, learning their needs and demonstrating how LangChain's products solve real problems in generative AI adoption. You'll drive proof-of-concept efforts in collaboration with sales engineers and product experts, negotiate pricing and deal terms, and manage contracts through legal review. Your responsibilities include staying current on product updates and industry trends, building long-term customer relationships, and supporting post-sale success in partnership with deployment and support teams. A key aspect of this role is bringing customer insights back to product and engineering teams to inform the roadmap and improve user experience. You'll also help define and iterate on the sales playbook, shaping go-to-market strategies as the company scales. You should have 5+ years of experience selling complex enterprise software, with strong relationship-building skills and the ability to establish credibility with technical decision makers. You thrive in fast-paced, unstructured startup environments, approach sales with empathy and curiosity, and are passionate about generative AI. Excellent communication, storytelling, and problem-solving skills are essential. You're driven to navigate roadblocks and keep deals moving forward while helping evolve the sales playbook rather than simply following one. LangChain has raised $125M at Series B from top-tier investors (IVP, Sequoia, Benchmark, CapitalG, Sapphire Ventures) and serves 6,000+ active LangSmith customers, including 5 of the Fortune 10 and 35% of the Fortune 500. The company's open-source frameworks have 100M+ monthly downloads.
