Senior Backend Engineer - Fulfillment Network Capacities B2B
Finland
· Full-time
·
Mid-Senior
Zalando fulfills more than a hundred million customer orders every year and volumes are increasing. The Fulfillment Core business unit within Zalando builds and operates systems that are at the core of Zalando’s platform strategy and ensure timely, efficient, and correct delivery of every one of our customers’ 185+ million orders every year.
As a Senior Backend Engineer in the Fulfillment Network team, you will build the Fulfillment Network Platform, which is the digital representation of Zalando’s European logistic network. The Network is the single source of truth for several key capabilities of Fulfillment Core, such as fulfillment planning and delivery time predictions. In this team, you’d enable the creation and usage of these properties and automate and improve the accuracy of network capacity demand forecasting with the mission to improve customer experience and fulfillment efficiency.
The team’s tech stack consists of Kotlin and Typescript for the backend microservices, with a focus on Kotlin going forward. We use Postgres for databases, Nakadi for event processing and deploying microservices in AWS on the Kubernetes platform. For observability, the team works with Grafana, Lightstep, and Scalyr.
