# Hire LangChain Developers

LangChain makes it quick to wire models, retrievers and tools together, and just as quick to end up with code nobody wants to touch.

- Senior, pre-vetted engineers only
- You interview and choose before anyone starts
- Working-hours overlap with India, the UK and the USA

48-hour turnaround · free · no obligation

### Talk to us about hiring LangChain developers

Tell us what you want to build. A senior engineer sends back a scope and a fixed price within two business days, no obligation.

In short

## The quick answer

Our LangChain developers use it and LangGraph where they help, keep chains small and traced, and leave you with something your own team can change.

The role

## What our LangChain developers do

### What our LangChain developers build

- RAG pipelines with LangChain retrievers and document loaders
- Tool-using agents and multi-step workflows with LangGraph
- Structured output extraction from emails, PDFs and forms
- Tracing and evaluation so failures are visible and fixable
- Refactors of fragile prototype chains into production code

### When to hire a LangChain developer

- Your LangChain prototype is hard to debug or extend
- You want agents that call your APIs and tools safely
- You need tracing and evaluation before going live
- You want a senior engineer to set patterns your team can follow

FAQ

## Hiring LangChain developers: FAQs

[Ask us something else](https://agilitytech.ai/contact)

**What do LangChain developers build?+**

LangChain developers build applications on top of language models: retrieval pipelines, chatbots, document extraction, and agents that call tools and APIs. With LangGraph they build multi-step, stateful workflows that can branch, retry and hand off to humans.

**Is LangChain production ready?+**

It can be, when it is used with discipline: clear abstractions, tracing, evaluation and tests. Our developers keep chains small and observable, and use plain code where a framework adds no value.

**Do you also work with LlamaIndex or plain SDKs?+**

Yes. We choose the lightest tool that fits. Many builds combine LangChain or LangGraph for orchestration with LlamaIndex or direct model SDKs where they are simpler.

**Can you take over an existing LangChain codebase?+**

Yes. A common engagement starts with a short review of your current chains, then a plan to stabilise, test and extend them.

**How do I start?+**

Book a call, share your stack and goals, and we send profiles of pre-vetted senior developers. You interview and choose, and the developers onboard without a long recruiting cycle.
