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
