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. \nWhat we do \nRELEX 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. \nWe’ve grown for 76 consecutive quarters straight, and it’s still accelerating. The first half of 2026 was the strongest in the company’s history. We’re a team of 2,000+ people, headquartered in Helsinki, with offices across Europe, North America, and Asia-Pacific. \nIn response to our fast growth, we're looking for a Product Engineer to help reinvent how RELEX builds and ships forecasting models. As a team, we own forecasting end to end for our retail and wholesale customers - both the new plugin-based models we're building and the models already running in production. 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. \nWhat we need you to do and be \nBring your ideas. Challenge ours. Grow with us. \nYou will design, build and improve our plugin-based forecasting models end to end: feature engineering, testing, and iterating on performance in live customer environments \nYou will take forecasting problems from business need to a working model running for a customer, with real ownership over the decisions along the way \nYou will work directly across multiple customer environments, figuring out what generalizes and what needs to stay customer-specific \nYou will use AI and agentic tools as a core part of how you build, pushing what they can do rather than using them passively \nYou will operate with a high degree of autonomy in a distributed team, without a fixed playbook for how the work gets done \nWhat you'll bring to the table \nOur five values are our playbook. We speak up when things don't make sense. We stop doing what doesn't add value. We stay curious, back each other up, and make space for both innovation and laughter. \nApplied or theoretical understanding of modern forecasting and modelling methods \nA proven track record of independently owning ML or modelling work end to end, from first concept to running in production. \nGenuine enthusiasm for agentic, AI-assisted engineering, and comfort being evaluated on how you reason through problems and direct AI tools, not only on manual coding \nComfort working with real ambiguity and no fixed process \nConfidence making decisions independently and shipping in weeks, not months \nComfort communicating directly with customers and cross-functional stakeholders \nWillingness to travel occasionally for customer work (roughly 1 to 2 trips a year) \nAs a bonus, prior experience in retail or supply chain is welcome but not required \nFluent in written and spoken English \nAs a bonus, we consider the experience of working with an international team, plus great communication and organizational skills \nWhat we offer in return \nYou'll be supported and given the space to thrive. We offer meaningful work, flexibility, and a culture that backs you to share your voice and be authentic. \nFirst-mover ownership of an agentic engineering capability that doesn't exist yet at RELEX, with real permission to start simple and fail fast \nAn international career and learning opportunities \nA rapidly growing and financially robust software company with exciting opportunities for career growth, also in the future \nFlexibility in how and where you work \nRoom to thrive in a fast-growing global company with a good market position \nPractical benefits that support work, family, wellness, and everyday life \nAnnual leave \nDiverse, inclusive, and supportive work culture \nWork that meaningfully reduces waste and improves sustainability \nOwnership, autonomy and flat hierarchies \nTwo paid volunteering days each year \nIf you feel this is the opportunity you don't want to miss, you can apply by sending your cover letter and resume through the application form as soon as possible. \nPlease note that to be considered for this position, you must be based in EMEA or Eastern US and hold a valid work permit for your location. We're excited to connect with applicants who meet these criteria and share our passion to do hard things, trust each other, and build what's next for the product, the planet, and the people. \nIf you have questions, from our Talent Acquisition team is happy to answer them by email. Please note that we cannot process any applications through email. \nApply today and be part of the future.
