About the job
LangChain is seeking a Deployed Engineer to join their team, focusing on building and running AI agents in production. This role involves working on complex applied AI systems that real teams depend on, with a fast feedback loop and visible impact. You will collaborate with customer engineering teams to co-architect and co-build production AI agents, own the technical win in pre-sales by designing POCs and answering technical questions, and help customers deploy and operate agent-based applications. You will also advise customers on architecture and best practices, run technical demos and trainings, and contribute reusable patterns and code. This position offers the opportunity to directly shape how AI agents are built and adopted in the real world.
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.
Requirements
- 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.
- Experience designing agent-based or LLM-powered applications beyond simple API calls, including multi-step workflows, orchestration, and failure handling.
- Comfortable working directly with customers during POCs, architecture reviews, and technical evaluations.
- Ability to explain technical tradeoffs clearly and build trust with developer audiences.
- Takes responsibility for outcomes, not just recommendations.
- Has a bias toward action and enjoys figuring things out as you go.
- Excited about operating AI agents in production, not just building demos.
Benefits
- Medical, dental, and vision coverage
- Flexible vacation
- 401(k) plan
- Meals on in-office days in the US
- Competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks.
