Jobbeschreibung

At Fabrikatör, we’re building the next generation of operational intelligence for commerce brands.

E-commerce teams still run their operations with spreadsheets, gut feeling, and disconnected tools. Forecasts break, stock runs out, money gets locked in inventory, and teams spend their days firefighting instead of building.

We’re fixing this.

Today, Fabrikatör helps brands plan inventory, manage supply, and make better decisions with real data.

Next, we’re going much further:

• An AI-powered Head of Operations that understands demand, supply, and constraints
• A system that lets planners simulate scenarios, compare outcomes, and get AI-assisted recommendations
• A platform that turns messy commerce data into clear, explainable decisions, not black-box predictions
• Software built for trust, clarity, and long-term thinking, not short-term hacks

You’ll be joining while the product is evolving fast, decisions are still being made, and your work will directly shape what thousands of operators rely on daily.

What will you do?

• We believe languages/frameworks are just tools to express your creativity and it’s what you build with these tools that matter.

Our tech stack mostly consists of;

• Backend: Ruby on Rails, Postgresql, Swagger, Cube
• AI: In the changing landscape of AI-assisted development, we use modern tools like Claude Code.
