Job description

About Wunderdog

We're a 70-person consultancy helping development teams get better at using AI tools to build things the right way and faster. Not through PowerPoint slides, but through hands-on training workshops and actual work in teams at companies like Finnair, Elisa, SOK, Alma Media, Sanoma, Blueprint Genetics, RELEX, Smartly and Babbel. Our focus is the development team and nothing else. We care about making teams better more than anyone else.

Software development has entered a new era where AI plays a significant role. Success requires pairing this with solid technical foundations and strong collaboration skills.

About the role

We’re looking for an experienced Mobile Developer to join us in Oulu. While your core expertise is in mobile development, software development at Wunderdog covers the complete technological spectrum: frontend, backend, databases, infrastructure, testing, and CI/CD. We value developers who understand the bigger picture and can work confidently across different parts of the stack, though you don't need to be a master of everything.

Our client projects span different industries, because software engineering fundamentals are the same whether you're moving packages, money, or people.

You need to be fluent in AI Native software development so you can help teams adopt practices that demonstrably increase their productivity. Interest in AI is expected, and we value down-to-earth pragmatism in how you apply it. Results today matter more to us than promises of future revolutions.

Consulting for us means shipping and helping teams get the ball rolling when they're stuck. You propose solutions and write the code to prove they work. You will be working as part of our client teams and can also lead Wunderdog's entry into new clients. You build trust through your work. You speak fluent Finnish and English.

We believe that AI amplifies developers with strong fundamentals into extraordinary product engineers, and we're looking for exactly that combination. If you have strong mobile development and software engineering fundamentals, together with communication and collaboration fluency, this is the place for you.

We work with these technologies, and we hope most of these are familiar to you:
