Production-Ready AI Job Classification in Python with LangChain and Cloudflare Workers AI
· 10 min read
We needed a pipeline that ingests hundreds of job postings from ATS platforms (Greenhouse, Lever, Ashby), enriches each posting with structured data from their public APIs, and then classifies whether a job is a fully remote EU position — all running on Cloudflare's edge with zero GPU costs.
This article walks through the architecture and implementation of process-jobs, a Cloudflare Python Worker that combines langchain-cloudflare with Cloudflare Workers AI, D1, and Queues to build a production classification pipeline.
