Job description

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.

With a global team of over 2,000 professionals, we work side‑by‑side with our customers to solve real problems with lasting impact. Companies trust RELEX to increase product availability, boost sales, deliver actionable insights, improve sustainability, and drive profitable growth. Join us and make an impact on the world and your career!

In response to our fast growth and market expansion, we are looking for a Forward Deployed Engineer to join our Merchandising team in [NEEDS INPUT: location]

Merchandising is where retailers decide what to sell, where, and at what price. Those decisions ripple out into less waste, better‑stocked shelves, and fairer pricing for millions of shoppers. A Forward Deployed Engineer (FDE) is embedded directly in the customer's environment to make that happen: configuring, extending and building on the RELEX platform against one customer's real operational context. Where our product engineers build one capability for every customer, you work the other way round, one customer and many capabilities, until their supply chain measurably runs better.

The role is embedded by design. You'll spend meaningful stretches of an engagement on‑site with customers, heaviest around discovery and go‑live, so willingness to travel is a condition of the role rather than an occasional extra.

What we need you to do and be

Bring your ideas. Challenge ours. Grow with us.

• 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

Our 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.

• 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
