Job Description

HelloFresh is one of the leading meal kit companies. They’re providing 111 million meals to 4.2 million households worldwide in 14 countries across 3 continents. From procurement tools to conversion rate optimization, live pricing tools, payment services and add-on upselling features, company works on a wide variety of challenging problems. Now HelloFresh is focused on creating internal tools for making supply chains more efficient and productive. There are some new incoming projects related to improving processes of comparing orders from the ordering tool (OT), goods received from the FCMS, and invoices from vendors. Some regions have developed stand-alone tools (i.e. Shark in AU), however, those tools do not scale company-wide and do not enable finance teams to work within the tools they are already using (i.e. Oracle).

  • Having an in-depth understanding of HelloFresh’s core product and architecture, and act as ambassador for software solutions offering support and mentorship to colleagues
  • Work with state-of-the-art technologies like Kafka, RabbitMQ, Spark, Kubernetes, Istio, and more

Requirements

  • 7+ years of commercial software experience

  • Background working with event-driven architectures using Kafka
  • Experience with stream processing
