Our Nordic roots and global outlook shape a culture of friendliness, creativity, and collaboration, all powered by openness and shared wins. We care deeply about doing the right thing, and doing it together. We aim to improve the flow of goods, time, and energy, and we know we can't shape the future by clinging to the past. So, we keep evolving, together.</span><span data-ccp-props="{"134233117":true,"134233118":true,"201341983":0,"335559740":240}">&nbsp;</span></p> <p><strong><span data-contrast="auto">What we do</span></strong>&nbsp;<br><span data-contrast="auto">RELEX runs the planning decisions behind 600+ retailers and manufacturers worldwide, deciding, at real scale, what gets forecast, stocked, priced, promoted, and produced across the entire value chain. Few problems combine this much data, this much complexity, and this much real-world weight: get it right and a shelf stays stocked, a factory line doesn’t stall, food doesn’t spoil in a warehouse before it’s sold. Get it wrong, and it shows up in actual losses, for some of the largest retail and manufacturing brands in the world.</span><span data-ccp-props="{"134233117":true,"134233118":true,"201341983":0,"335559740":240}">&nbsp;</span></p> <p><span data-contrast="auto">We’ve grown for 76 consecutive quarters straight, and it’s still accelerating.

We're reinventing how RELEX builds and ships forecasting, moving from a small number of monolithic models to a growing library of purpose-built, plugin-based ones, used by 400 to 500+ customers. This role sits at the core of that.</span><span data-ccp-props="{"134233117":true,"134233118":true,"201341983":0,"335559740":240}">&nbsp;</span></p> <p><strong><span data-contrast="auto">What we need you to do and be</span></strong>&nbsp;<br><span data-contrast="auto">Bring your ideas.
