What we do RELEX Solutions delivers a unified supply chain planning platform for retailers and manufacturers, enabled by proven AI technology. We help companies optimize demand forecasting, replenishment, merchandising, pricing and promotions, supply chain operations, and production planning across the end-to-end value chain. Who we are We work on the decisions where retail margins are won and lost. Changing a price is easy. Knowing which of fifty thousand prices to change, what it does to demand, and whether last week’s promotion actually made money is not. That is what we build for. RELEX Solutions delivers a unified supply chain and retail planning platform for retailers and manufacturers, enabled by proven AI technology, with a global team of over 2,000 professionals working side-by-side with our customers. The role In response to our fast growth in Europe, we are hiring a Forward Deployed Engineer with a software engineering foundation for our Merchandising business. You will be part of the central engineering team, and work with the operations team, directly with our customers. You will be the scientific and technical face of RELEX Merchandising to European retailers. What makes this role different This is not a consulting role and not a solutions architect role. You write production code and build production models that run in live customer environments. The hard part of this job is not prototyping quickly. The hard part is that the improvement you co-develop has to be right, hold up in front of the customer’s own analysts, and then run in production every week. You walk in with a hypothesis, test it on their data, and stand behind the result, limitations included. What we need you to do and be - Own technical delivery end to end, from discovery through go-live: configuration, extensions, integrations, and the quality of everything that ships into the customer's instance - Prove the value you deliver by instrumenting deployments, measuring outcomes against the customer's baseline, and presenting the evidence credibly to operational users and executives alike - Own the technical customer relationship, learning their operations deeply enough to challenge requirements and become their first call when a new problem appears - Feed the product by capturing gaps and use cases from the field and prototyping solutions that can graduate into the RELEX roadmap - Build customer self-sufficiency through knowledge transfer and clean handovers, so they can operate and extend RELEX without you - Grow the account by surfacing adjacent use cases, new sites and unused capabilities, and shaping the technical solution and value case together with pre-sales and the account team - Support commercial activity with feasibility assessments, proofs of concept and technical demos, so what gets agreed is technically grounded What you'll bring to the table - Proven experience designing and building software across the full stack, in production, not just in dev - Strong understanding of system design, observability, and hypothesis-driven development - Experience building integrations for downstream or customer-facing systems - Solid working knowledge of cloud platforms and modern application stacks - Strong business acumen: you can translate technical work into measurable financial impact and communicate it clearly to a non-technical audience - Comfortable managing ambiguity and taking full ownership of outcomes - Willingness to travel and to work on-site at customer locations for parts of an engagement - Comfortable using AI in your everyday work and developing AI tool adoption as an organizational strategy - Fluent in written and spoken English - Nice to have: exposure to retail, merchandising, or pricing and promotions - More important: you learn a new domain and a new codebase fast, and you're comfortable being productive before you feel fully up to speed What we offer in return - An international career and learning opportunities - A rapidly growing and financially robust software company with exciting opportunities for career growth, also in the future RELEX key benefits - Flexibility in how and where you work - Room to thrive in a fast-growing global company with a good market position - Practical benefits that support work, family, wellness, and everyday life - Annual leave - Diverse, inclusive, and supportive work culture - Work that meaningfully reduces waste and improves sustainability - Ownership, autonomy and flat hierarchies - Two paid volunteering days each year We are a global community of different cultures, voices, and experiences. We celebrate what makes us unique and connect through what we share, in an authentic and safe environment. Together we shape the future, and each other. Please note that to be considered for this position, you must be fluent in English, and hold a valid work permit for the country you reside in / will work in. 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.
