Location: Gothenburg 



Scope of role:

We are currently looking for an iOS Developer who wants to play a major role in a small, fast-growing company. 

You will join our Core team, which works with AI and Machine Learning to develop and improve the very heart of Sleep Cycle; our sleep analysis.

We strive for quick feedback loops and keep the time between a merged pull request and a release short. You will be working closely with other talented engineers, being involved from the initial idea to measuring how our audience interacts with it. 

Git flow, continuous deployment, on-site QA; Our development process is as smooth as a good night’s sleep. Constructive feedback and debate is encouraged in all our teams, helping us bring out the best in everyone and in our work. 


About you:

In order to thrive in the role, we think you;

  • Have senior experience from Swift and Objective C (the years in itself are of less importance, it’s your approach that matters)
  • Like to work together with others in a cross-disciplinary environment
  • Are flexible and can change priorities in a fast growing company
  • Like algorithms and AI - make it simple
  • Good understanding of multithreading issues and solutions
  • Enjoy to take on the overall responsibility for not only the code but also the UI and occasionally some QA tasks
  • Prefer to invest a bit more time into the task and deliver good quality rather than “quick and dirty” fixes
  • BS or MS in Computer Science or related field (required)


Awesome (but not required) if you have:

  • Experience with Machine Learning - preferably Core ML-  on Android, iOS or other embedded platforms (PyTorch, Tensorflow and others)
  • Experience working with Open source projects to contribute the wider iOS community

We value a welcoming and warm attitude above all else, and we believe that each of us, as individuals, can only thrive in a nurturing and challenging environment. Taking a break and having a good laugh are cornerstones of life at Sleep Cycle, and we truly enjoy each other’s company. 


If this sounds interesting to you, please submit your application in English as soon as possible.
