Are you passionate about software engineering and especially Scala? Are you open-minded about approaches and techniques, willing to pick the best tool for the job? Would you like your skills to have a real impact on the market? Are you keen on working with world-class teammates in a successful startup to bring a product to the market that will change a billion-dollar industry? Well, this position might be just for you!


SO1 is the leading AI in retail.

We have built and are expanding a revolutionary promotion platform based on cutting-edge algorithms and seamless (offline) retail integration. On this platform, we allow retailers to target consumers truly individually and in real-time with the most efficient discounts. Our artificial intelligence – the SO1 Engine – learns from millions of consumer transactions and derives the right impulse to induce a specific consumer to switch from one product to another, buy additional items, and/or visit a retailer’s store.

SO1 has been backed by high-profile investors Target Partners and Shortcut Ventures with 8-figure investments.


As a software engineer at SO1, you will be a core part of the software team and will be responsible for the design, development, and improvement of complex software systems and APIs. Together with our high-class researchers you will translate algorithm prototypes into production-ready code and manage the full software stack from ground up. SO1 is running on Scala – so whether you are a Scala veteran or you are a Scala novice, we expect you to constantly learn and refine your skill set.
