S'more About The Team

The Production Scheduling Technology team builds and maintains the platform that powers how HelloFresh plans, sequences, and optimizes production across our operations. Our team has developed the first iteration of the next-generation internal system with a planning engine that now automates the end-to-end planning process - a system with deep impact on how millions of meals move through our network. As we continue evolving this system, extending its capabilities, and preparing for expansion, we are looking for a Senior Software Engineer with strong backend experience, a talent for turning complex logic into clean, reliable systems, and enough full stack fluency to support and enhance our internal application. Above all, we are looking for people who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences! So even if you don’t "tick all the boxes" but think you’d thrive in this role, we would really like to learn more about you.
