Jobbeschreibung

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

  • Own and ship end-to-end features – from API design and data models to polished UIs and production monitoring.
  • 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.

Requirements

  • Strong Python skills - clean, maintainable, well-tested code matters
  • Professional experience with React/Next.js and TypeScript
  • Experience in data engineering and backend architecture
  • Comfortable building and scaling RESTful APIs
  • Curiosity about how LLMs can be used in real-world settings
  • A builder mindset - you like to ship, measure, and iterate rather than bikeshed
  • Comfort with ambiguity and ownership: you spot problems, propose solutions, and drive them to completion without waiting for perfect specs
  • 4+ years experience in relevant (Start-Up) roles

Benefits

  • Build AI agents that actually do things
  • Massive autonomy, zero bureaucracy
  • Immediate impact, your work ships fast to real customers
  • Modern stack, no legacy
  • Competitive salary + meaningful equity
  • High-end equipment

Tech Stack You’ll Work With

  • Python (FastAPI, LangChain, LangGraph, LangSmith)
  • Next.js, React, TypeScript, TanStack Query/Router
  • AWS (Bedrock, ECS Fargate, Lambda, SQS/SNS)
  • GitHub CI/CD , Sentry & Grafana & Prometheus
  • Postgres, Redis
  • Large Language Models (LLMs) and evaluation tooling
