LangChain is the orchestration framework for building applications on large language models, from retrieval pipelines to agents. Postings name it in AI engineer, machine learning engineer and full-stack roles building generative features.

LangChain is a pure hiring signal: nothing about it is visible from outside. A company posting LangChain roles is building LLM applications in earnest, which is the qualifier vector-database, evaluation and model vendors look for.

## How JobsPipe detects LangChain

Every posting is parsed for technology mentions: the title and description are matched against a curated lexicon and the matches are stored on the job as `technology_slugs`. A posting that names LangChain carries the slug `langchain`. The `skills_or` filter on `POST /v1/jobs/search` returns every such posting with its company, location, seniority and salary where stated.

```bash
curl -X POST https://api.jobspipe.dev/v1/jobs/search \
  -H "Authorization: Bearer $JOBSPIPE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"skills_or": ["langchain"], "status": "active", "limit": 24}'
```

This is a hiring signal, not a purchase record: a company can name LangChain because it runs it, because it is migrating to or away from it, or because candidates are expected to know it.

### How does JobsPipe know a company uses LangChain?

JobsPipe extracts technology mentions from each posting's title and description against a curated lexicon and stores them on the job as technology_slugs. A company appears on this page when its active postings name LangChain. It is a hiring signal, not proof of a purchase: a posting can name a technology a team is migrating away from or only wants experience with. LangChain runs behind login or inside the company's own infrastructure, so a website scan almost never sees it and job postings are the only public evidence of adoption.
