Lead Product Designer | Platform Engineering

Who we are

We’re bold thinkers and kind teammates, growing fast but staying grounded. 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. 

What we do

RELEX runs the planning decisions behind 700+ 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 rot 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.

We’ve grown for 76 consecutive quarters straight, and it’s accelerating: the first half of 2026 was the strongest in the company’s history, with new contract value up 83% year over year. We’re a team of 2,000+ people, headquartered in Helsinki, with offices across Europe, North America, and Asia-Pacific.

In response to our fast growth and market expansion, we are looking for a Lead Product Designer to own the user experience of core platform capabilities end to end, embedded directly with the teams that build them. 

You are a Lead-level designer with excellent design judgement and the skills to understand platform users’ needs and product goals. You apply agentic engineering workflows to ship features into production and contribute directly to delivering customer value. This is a hands-on role where you shape the scope of the work and are accountable for high-quality design outcomes.
