Responsibilities

About the Role

We are building our AI/ML platform, and we are looking for a senior full stack engineer who wants to own product outcomes. You will work on the product, shaping how features are built, making pragmatic technical calls, and turning ambiguous problems into things operators actually use. This is a hands-on senior role: you will write production code across the stack, but you will also help shape what we build and why. This role is offered in the UK or Finland, with flexible hybrid and remote working. We are also open to engaging candidates in Poland on a B2B contract basis.

What we offer

• Competitive salary and benefits package.
• The opportunity to work on cutting-edge technology projects with major clients.
• A supportive, collaborative, and innovative work environment.
• Continuous professional development opportunities.
