About the role

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 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. 

We’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. 

In 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. 

What we need you to do and be 
Bring your ideas. Challenge ours. Grow with us. 

You will design, build and improve our plugin-based forecasting models end to end: feature engineering, testing, and iterating on performance in live customer environments 

You will take forecasting problems from business need to a working model running for a customer, with real ownership over the decisions along the way 

You will work directly across multiple customer environments, figuring out what generalizes and what needs to stay customer-specific 

You will use AI and agentic tools as a core part of how you build, pushing what they can do rather than using them passively 

You will operate with a high degree of autonomy in a distributed team, without a fixed playbook for how the work gets done 

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. 

Applied or theoretical understanding of modern forecasting and modelling methods  

A proven track record of independently owning ML or modelling work end to end, from first concept to running in production. 

Genuine 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 

Comfort working with real ambiguity and no fixed process 

Confidence making decisions independently and shipping in weeks, not months 

Comfort communicating directly with customers and cross-functional stakeholders 

Willingness to travel occasionally for customer work (roughly 1 to 2 trips a year) 

As a bonus, prior experience in retail or supply chain is welcome but not required 

Fluent in written and spoken English 

As a bonus, we consider the experience of working with an international team, plus great communication and organizational skills 

What we offer in return 
You'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. 

First-mover ownership of an agentic engineering capability that doesn't exist yet at RELEX, with real permission to start simple and fail fast 

An international career and learning opportunities 

A rapidly growing and financially robust software company with exciting opportunities for career growth, also in the future 

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 

If 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. 
Please 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.
