Backend Developer - Java
Your work will have a tangible impact on the way that we operate and we promise that you’ll be challenged, pushed to develop your skillset, and have the opportunity to work with amazing people!
About the role
You’ll be part of an agile autonomous team working on extending and refining our core systems. Our teams solve a wide array of complex problems, below are some examples.
Capacity management - We believe in quick, exact, and efficient delivery. To know when we can deliver a specific parcel, or how to maximize locker compartment utilization, we continuously adapt and gain knowledge about of the current parcel delivery capacity in our locker network and how it changes over time. We use machine learning to model consumer pick-up behavior and forecast future parcel volumes from merchants.
Driver route optimization - Driving is at the core of what we do. Well-planned routes are essential for driver happiness, consumer satisfaction, and our ability to offer sustainable deliveries.
Locker fleet management - Our lockers are equipped with a tailor-made computer, a 4G modem with an intuitive interface. With a large growing fleet of lockers in multiple countries, we solve problems such as performing safe and secure software roll-outs, inventory management, and detection of malfunctioning hardware.
About you
We’re hiring for multiple teams and we are looking for both senior engineers or you with a couple of years of experience looking for your next move - If you are a skilled problem solver who loves coding and making complex things work, then this is the place for you! At our company we value individuals who are keen to learn, and your eagerness to develop your skill set will probably be your strongest asset when joining us. Beyond that we imagine that you have the following:
- At least 3 years of work experience as a Backend Engineer in a modern tech environment
- Working with JVM-based languages such as Java/Kotlin/Scala
- Ability to think creatively to solve problems

In order for you to thrive you need to like the fast-paced environment and not be afraid to get shit under your fingernails. Let's be honest, we are in an incredibly exciting phase where much is uncertain and not decided. In this business, you need to have thick skin to get by, like changes and not be afraid to set new structures, set processes, and create new WoW.
Diversity and inclusion are very important for us, and we also know that we don’t know everything. So if your passion is problem-solving, and coding and you have a strong willingness to learn, but don’t tick all the boxes above – don't hesitate to apply no matter who you are and let us know how you can contribute to our journey.
