Could your next career step be in in-house mobile development in one of the largest software houses in Finland? Are you fascinated by the idea of millions of customers accessing the IT solutions you develop?


Senior Developer (Mobile, Backend), Oulu


OP Mobile is an application that reaches customers extensively on a Finnish scale and has more than a million active users. A total of about 40 people are involved in the development of the application, and we are currently looking for confirmation for a team of approx. 10 people responsible for developing OP Mobile's existing operations and creating new functionalities. We are an active, fast-paced, and creative bunch of developers waiting for you to join us!


As a Senior Developer, you will focus on developing OP Mobile's new functionalities for multiple feature areas. You get to work, for example, with payment solutions and financial management functions (such as financial predictability) and but also on creating stronger and better DevOps practices to support development. Lately, we have also been working with multiple themes related to the constantly growing field of mobile payments. Together with other teams, you’ll also get a chance to solve the challenges related to purchasing customers and concretely make their daily lives smoother. However, delivering a high-quality mobile application that delights and retain users requires reliable backend services, and this is where we especially need your help. And, not to mention, the role itself offers multiple challenges also from a guiding and tech leadership point of view.


So, your days are made up with:

  • OP Mobile's development work
  • Strong daily collaboration with internal stakeholders and our team (for example, Apple Pay, mobile payments)
  • Continuous improvement, both from a technology and WoW point of view
  • DevOps mindset and inspiring approach 




  • Previous work experience of backend (Java) development and/or mobile development
  • Technology skills: Java, Spring, API design & development
  • Experience of AWS environment
  • Experience working in a DevOps environment with automated CI/CD processes including test automation 
  • DevOps mindset and inspiring approach blended with a passion for problem-solving 
  • Good oral and written English language skills
  • Seniority and technology leadership


We appreciate your strong technical background, but we also hope you have the courage to think and the courage to try new ideas. At OP, we are inspired by Agile teamwork and working together, so we hope that you will be an enthusiastic and actively involved colleague working with others. For us, DevOps means a state of mind where efficiency and quality meet through doing things together. Come listen to what Devops means in our activities and take a look at what our devotor's day really looks like!



As an operator in the banking sector, you could easily imagine anything else, but we are one of the largest IT houses in Finland and we produce the IT solutions visible to customers mainly independently from start to finish. Oulu employs about 400 people and the entire OP Financial Group about 12,000 people, so a wide range of expertise can be found from experts in various fields. That is why there are thousands of experts in the field in our house, and the developer culture, for example, already seems strong today. 
We also encourage and help you to further develop yourself as a technical professional. We have the so-called “70/20/10 rule” in use, which means you will use 70% of your time for your daily tasks, 20% to develop the way you do those tasks, and the last 10% is reserved for you to learn and try new things. You will also have our OP Software Academy at your disposal in case you are interested in learning new technologies or methodologies, or why not in honing your skills in your current stack.
And of course, we have a wide range of staff benefits including a personnel fund and special terms for employee banking, insurance, and loan services. We offer comprehensive occupational health care, extensive medical treatment expenses insurance and a full-time group accident insurance policy, just to name a few.
