Job summary

LangChain is seeking a hands-on, highly technical Sales Engineer to partner with customer teams, co-design agent architectures, and drive the technical win in pre-sales. You’ll work on production AI agents with customers and help deploy and operate agent-based applications at scale.

The role emphasizes direct customer engagement, architectures decisions, and delivering reusable patterns and demos to a broad set of clients.

Qualifications

• 3+ years in a relevant technical role (software engineering, customer engineering, solutions engineering, founding/product engineering) ideally in a startup or scale-up.
• Strong Python, JavaScript and systems fundamentals.
• Have designed agent-based or LLM-powered applications beyond simple API calls, including multi-step workflows, orchestration, and failure handling.
• Are comfortable working directly with customers during POCs, architecture reviews, and technical evaluations.
• Can explain technical tradeoffs clearly and build trust with developer audiences.
• Take responsibility for outcomes, not just recommendations.
• Have a bias toward action and enjoy figuring things out as you go.
• Are excited about operating AI agents in production, not just building demos.

Responsibilities

• Co-architect and co-build production AI agents with customer engineering teams.
• 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 scale across customers.
• Occasionally contribute code upstream when it meaningfully improves customer outcomes.
• This role requires 40% travel to customer sites to support deployment, onboarding, and ongoing technical engagement.
