Our open-source implementation is one of the fastest growing data projects on GitHub and has over 30 thousand stars and 100 million downloads to date.We believe data processing should be a seamless experience from working locally on your development machine to an enterprise production environment. There should be one framework to learn for data practitioners, removing the need for rewriting code when going to production. To make that possible, we are building a cloud platform to seamlessly bring locally developed Polars pipelines to production. We are also building a distributed engine for Polars to scale beyond the limits of a single machine, both in the cloud and on-premises.## How will you make an impact?As a member of the compute team you’ll be responsible for the performance of our query engines. You’ll discuss optimization techniques ranging from isolated bit fiddling tricks to central design changes with your team members.
