We are looking for a Principal Product Data Scientist, interested in pushing the boundaries of dev ops analytics to make sure speedy technology updates can be done safely in all of our games.

Be a part of Client Foundations, bringing flow to other developers within King. We are a team of 20+ skilled, knowledgeable, and passionate people.

We are cross-located in Stockholm, London, and Barcelona with a flexible hybrid working model.

You will work with establishing A/B testing for technology releases and building observability into our tooling offering. You will both act as a senior mentor as well as an individual contributor. You will be working closely with varied team members in a fun, dynamic and fast-paced environment. You’ll possess the role of a domain expert in product data science for our area, and be part of the community of 80+ business intelligence & analytics experts at King.

Specifically you will:

  • Identify business risks with technology releases for each game through A/B tests.

Skills to Create Thrills

Our ideal candidate will have solid experience nurturing an analytical team in a technical environment. There is plenty of scope at King for you to learn from your colleagues in the areas where you have less experience, and to share your own skills where you are stronger.

  • Stats: Design, implement, and analyze multivariate tests using relevant statistical methods and measures of performance.
  • SQL: Able to write complex SQL queries to analyze our databases with 300+ million players and work with relational database systems.

  • Communication: Designing good ways of communicating, visualizing or reporting your results/analysis so they are clear and unambiguous
  • Leadership: The ability to mentor, guide and inspire your colleagues and drive best methodologies across the company
  • Partner Management: The ability to recognise dependencies, build relationships and influence others
  • Technology expertise: Understand software development, devops practices and QA.
