About the Team
We are the team responsible for ensuring that parcels move through our terminal network in the most efficient and cost-effective way possible. Our systems provide sorting instructions that guide parcels between terminals and to their final destinations, whether that’s a customer, parcel locker, or delivery partner. We also deliver real-time parcel data and location insights, enabling smooth and transparent operations across our entire sorting network.
Our Vision
Our objective is ambitious, We strive to achieve operational excellence across our 40+ terminals in Europe. Any parcel should be able to enter the terminal sorting network at any point and immediately be ready for the next step towards its destination. To achieve this, we ensure that everyone interacting with a parcel — from systems to people — can make smart, fast, and data-driven decisions that minimize the total cost of the flow.
How We Work
We are a team that listens to what’s needed now, tomorrow, and in the future. Collaboration, experimentation, and continuous improvement are at the heart of how we operate. The team consists of our Engineering Manager, three skilled Backend Engineers, a Product Manager, and a Staff Engineer. This recruitment is to replace one of our Backend Engineers who recently resigned.

Participate in incident management and ensure learnings turn into long-term improvements.
Collaborate across teams and domains to ensure smooth integrations and a unified technical approach.
About You
You’re an experienced backend engineer with solid experience in Go (or a similar strongly typed language). We mainly work with Go, but you'll touch legacy systems built in JavaScript, Python, Java, or Kotlin. If you’ve seen a bit of everything and enjoy bringing old systems up to modern standards, that’s a bonus!
You have a deep understanding of building distributed systems and APIs in a cloud environment (preferably GCP or AWS).
