RELEX Solutions is at the forefront of developing data-driven supply chain and retail planning software. Our innovative platforms enhance adaptability, efficiency, and sustainability within the consumer goods and retail value chain. Our work makes a tangible impact by reducing waste, boosting profitability, and delivering value to our customers through our powerful software platform.  

Technology at RELEX    
The RELEX Price and Promotion application runs cloud-native on Google Cloud Platform and is a mix of Golang backend services and a Typescript/React single-page application. Our data platform also runs using Golang and Cadence/Temporal workflows, ingesting and enriching millions of rows of raw customer data into a hybrid data layer driven by ClickHouse and Postgres. We serve these enormous data sets and sales forecasts through a mix of pre-calculated and on-the-fly analytics that must be both user-friendly and responsive.  We perform advanced ML and AI using a number of platforms, increasingly concentrating on pyTorch. 

We offer flexibility in our work arrangements, allowing you to choose between remote or in-office work. Respect and collaboration are core to our culture, and we prioritize a genuine work-life balance while ensuring we deliver an exceptional product.
