Full Time in Helsinki, Finland

Backend Developer, Python

Posted in November 14th, 2016


At ŌURA we are building one of the world’s richest data sets for sleep and recovery, which offers us a unique position in developing product experiences that help our customers to improve their well-being. Managing and analyzing this data is critical for our success, and we are now looking for an experienced Python Backend Developer to strengthen our team.


Your responsibility is to design, develop, test, deploy and maintain the ŌURA backend software together with the rest of the team.

Initially we expect you to work on multiple areas: web app and API development, devops and data analysis. As the team grows, you can start concentrating more on one of these areas. For example, if you are passionate about data analytics and machine learning, you will have the opportunity to grow to lead our server-side data science efforts.

Our technology stack

Our backend stack is built on Amazon Web Services (AWS), utilising many AWS services such as EC2, RDS, S3, SQS, SNS and Lambda to manage our data flows. Our server software uses Python, SQLAlchemy and Tornado, nginx and PostgreSQL, and we use Ansible as a part of our deployment. Familiarity with all these technologies is not required – continuous learning is part of the job. However, it’s important that you have a good grasp of the benefits and tradeoffs of different backend technologies, such as relational databases, key-value databases and task queues.

Minimum qualifications

  • Excellent programming skills, and specifically solid Python experience
  • Good understanding of relational databases
  • Experience in running production backend systems, preferably on AWS
  • Solid experience of standard software development tools and practices: version control (git), issue tracking, unit testing and agile development processes

Preferred qualifications

  • Master’s or PhD Degree in Computer Science or other technical field
  • Work experience in AWS stack and efficiently managing and monitoring data flows
