Job Description:

King operates games at a massive scale, serving hundreds of millions of players around the world. Behind every player experience is a large ecosystem of services, data platforms, forecasting systems, and internal tools that help our teams make better decisions, move faster, and deliver exceptional experiences.

You will collaborate closely with software engineers, data scientists, analysts, product managers, and business stakeholders to build scalable solutions that transform complex data into actionable insights.
