We’re looking for an experienced platform engineer to help us scale the platform as we grow.

You will work on making highly scalable solutions, get feedback from analytics and monitoring tools and be able to refine and perfect your solution at each iteration.

Tech-wise, our server code is written in Python and running on AWS (RDS, EC2, ElastiCache, etc). You will soon get familiar with distributed computing, cloud hosting, database optimizations and search solutions. 

This role is a good fit for analytical and creative software engineers loving team work. We work closely in a scrum team and follow the motto “team work is better work”. You want to grow and learn from others, and you also want to teach and help others grow. 


  • Taking features from the idea stage to scalable production deployments
  • Take part in improving the platform as a whole as the company grows


  • Passion. You love building scalable systems, big data problems and high performance applications.
  • 5+ years software development experience 
  • Demonstrated experience building, maintaining and optimizing large-scale consumer web/mobile applications.
  • You have worked in a team of developers and know the benefits of tests, continuous integration, logging and monitoring
  • You have experience working in Python or a similar language
  • You are a team worker with excellent communication skills
  • Fluent (written and verbal) in English
  • It’s a plus if you have a passion for health and fitness 

As a person you continuously challenge yourself to find new ways of developing our platform. You have a burning desire to improve and you are not afraid to roll up your sleeves and get the work done.
