Wat ga je doen?

Supply chain logistics is the science and art of monitoring and managing the flow of resources, information, and goods from one destination to another. An essential requirement in achieving operational excellence across a supply chain is foresight, particularly the ability to project awareness of the current situation forward. We are looking for a Senior Software engineer to help us build out a Control Tower solution that will watch over our entire digital and physical operations in near-realtime.


As a Senior Java Engineer, you will work on the design and development of shared supply chain logistics model libraries used across platform components that operate primarily independent of the specifics of the execution environment - local or cloud. You will have experience designing extensible and adaptable mechanisms that allow the same interface(s) to be used consistently and correctly with different configuration parameters, sources, and sinks of data, plugins, and implementations while been relatively easy to integrate into different runtimes and environments.

Onze ambitie

We are building the digital future of PostNL Parcels. With our fundamental approach to data we will digitally transform our supply chain and allow for real-time and automated decision making. 

  • 5 years' experience in Java (preferably some knowledge of Kotlin);
  • Proven track record in API/Library design;
  • Deep understanding of concurrent programming constructs;
  • Working experience with one or more reactive- and actor-based libraries and systems (Akka, Reactor, etc);
  • Knowledge of event-driven simulation architectures and runtimes;
  • Ideally, prior experience with the design and development of supply chain logistics solutions;
  • Strong systems analytical mindset with good communication and organizational skills;
  • Some experience of AWS Cloud.


Having prior experience in modeling, monitoring, and managing supply chain logistics would be an added advantage, as would an understanding of data lineage, enterprise data management, machine learning techniques, and technologies.
