Deployed Engineer (San Francisco)

LangChain

San Francisco, CA

Annual OTE: $150,000 - $250,000 USD

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.

Today, LangChain, LangGraph, LangSmith, and Agent Builder 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.

With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we are at a stage where we are continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together.

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

You will 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.

Locations: West (San Francisco, Pacific Northwest, Southern California), Central (Austin, Chicago, Denver), East (New York, Atlanta), EMEA (London, Amsterdam)

What You Will 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 Will 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

You have 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

Compensation & Benefits

Competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks. Benefits include medical, dental, and vision coverage, flexible vacation, a 401(k) plan, and life insurance. Team members in the EU, UK, and APAC receive locally competitive benefits aligned with regional norms and regulations.
