Zalion is an international AI start-up revolutionizing industrial procurement. We use cutting-edge AI agents to automate manual Source-to-Pay processes, freeing up procurement teams for strategic work.

We are live with the largest companies in Europe & the US.

We love what we do. We get stuff done. We progress fast.

Tasks

Build scalable backend APIs in Python/FastAPI
Ship high-quality frontends using Next.js (React, TypeScript) + TanStack (Query/Router).
Design and evolve agent workflows in LangChain/LangGraph that are robust, observable, and debuggable (not just prompt hacks)
Work with both structured and unstructured procurement data (RFQs, emails, quotes, contracts)
Build data & system integrations (ERP, email, supplier systems)
Help shape our architecture, reliability, and engineering best practices as we grow
Collaborate directly with founders, PM, and customers to understand real procurement workflows and turn them into product.
