This vacancy has been created based on interviews with employees to help you get a realistic preview of the job.


As a Software Engineer at Adcombi you are responsible for developing new tools, which are immediately used by international advertisers and media companies. You do this together with a team of three experienced developers. Your daily tasks include writing tests, reviewing your colleagues’ code and creating new features for a variety of apps and services. You primarily work with Ruby, Ruby on Rails and JavaScript. You also participate in estimation sessions where work that has been requested is discussed and estimated into tickets depending on the complexity and type (features, bugs, tasks, etc.). During the sprint, you can then pick up tickets on Jira, the issue-tracking platform. At the end of each sprint, you’ll also do a team sprint review to discuss how it went.

You perform your tasks independently or in pairs. Working and discussing work together is very important within the Development team.

If you enjoy both front and back-end programming, and you don’t mind quickly switching between different tasks and contexts, then this is a job you would enjoy.

Firsthand experience

A colleague from the Operations department contacts you and says he gets an error message when he uploads his Excel file. What do you do?

Usually your colleagues submit requests or questions through Jira. The team can then deal with them together and determine their priority and validity. It is also possible that a colleague comes up to you and asks you something. Firstly, you check whether it is urgent, for example, if the current situation is causing problems for an on-going campaign. In this case, you ask them if they can send you the Excel file so that you can reproduce the bug. Then you identify where exactly the problem lies. If it seems to be a large bug, you indicate you are unable to solve it immediately and tell them it has to be looked into more. If it is a small fix, which can be solved by rewriting a small piece of code, then you do this immediately. Lastly, you see how this bug can be avoided in the future. If it appears it may be something that could resurface, you write an automated test for it. Other Software Engineers can then carry this out should it happen again.


Adcombi is currently in the scale-up phase. This gives you the opportunity to grow and have a say. You are able to develop both in a broad sense. Education and training are offered, depending on the need.
