Back-End Developer, Seinäjoki


True perfection never rests, and that’s why we don't either!

We are looking for a Back-end Developer to join our family of over 700 highly skilled digital craftsmen and –women. Siili builds value-adding digital services together with our clients. In our everyday work, we believe in clean code and test automation. Our developers are modern artisans who craft the code, choose the tools and build the serverless environments. We are strong believers in continuous learning and always want to develop further. 

What are we looking for?

We expect you to be a skilled developer with previous experience in software development and agile methods. We hope you share our passion for continuous development and want to develop your skills further with modern technologies no matter what your current stack is. We expect that you have skills in Java, preferably some interest towards functional programming, lean/agile ways of working and fluency in Finnish + good level of English. We would also be really happy to see cloud technologies (AWS, Azure), microservices and/or modern platforms such as Docker in your background.

What do we offer?

At Siili, you will be a part of a tribe where modern artisans have gathered around similar interests. Belonging to your tribe ensures that you have the support of a Tribal lead, sparring partners when you need them, and regular contact with like-minded people. We offer you the chance to work with the best colleagues, Siilis, and with the best clients and projects. You will never be bored – we strongly believe in continuous improvement, which means you will always be able to deepen your expertise with us. Being a Siili means that you get to work with different teams, yet be the master of your own work – we trust you.
