Deployed Engineer

About Us

At LangChain, our mission is to enable every company to own its intelligence. We believe agents will transform how companies operate, and we're building the foundation to make that future possible. Our open-source harnesses and LangSmith platform give developers and enterprises the infrastructure to run, improve, and govern agents at scale.

We've raised $460M to date, with our most recent funding round valuing the company at $3B, backed by leading investors including Sequoia, Benchmark, IVP, and CapitalG. As we continue to expand our platform and tackle some of the hardest challenges in agent engineering, every team member has the opportunity to make a meaningful impact and help shape both our technology and the future of the industry.

More than 7,000 organizations rely on LangSmith, from fast-growing startups to Fortune 500 enterprises, including NVIDIA, Bridgewater, LinkedIn, Workday, and Rippling. We're just getting started on making high-performing agents easier to build and manage at scale.

About the Team

The Deployed Engineering team works directly with companies building and running AI agents in production, helping turn ideas and prototypes into systems teams can rely on.

This is a hands-on, highly technical team that partners closely with customer engineers across the full lifecycle, from pre-sales evaluations to post-deployment advisory work. The focus is on achieving the technical win, co-designing agent architectures, and helping customers operate agents reliably at scale using the LangChain suite.

Deployed Engineers sit at the intersection of engineering, product, and go-to-market, shaping how LangChain is adopted in the field and feeding real-world insights back into the platform.

About the Role

The Deployed Engineer…You’ll work on some of the hardest problems in applied AI — not demos, not research, but systems that real teams depend on in production. The feedback loop is fast, the impact is visible, and the work you do directly shapes how AI agents are built in the real world.

What You’ll Do

• 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

What You’ll Bring

• 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

Nice to Have’s:

• You’ve deployed AI agents in production, especially using LangChain, LangGraph, or similar frameworks

• Worked with LLM evaluation, observability, or guardrails

• Have experience with cloud environments (AWS, GCP, Azure), containers, and basic Kubernetes concepts

• Have shipped and operated production software and are comfortable owning systems under real-world constraints
