Build what's next in data
Join the team pioneering a faster, simpler future for data processing, and pushing what's possible along the way.
We are Polars
Polars is built on the foundation of a vibrant, active open-source community, and we run the company the same way. We trust talented people to do their best work without unnecessary constraints. Collaboration matters, but we keep meetings to a minimum to protect focus. As Polars and Nanook continue to set a new standard in data processing, we're looking for like-minded people to join us on that journey.
Our core beliefs
Progress over perfection
When faced with uncertainty, we favor pragmatic solutions over long discussions, especially when the decision is reversible. Building software is an iterative process, you learn the true impact of a feature along the way.
Craftsmanship
We take pride in what we build and deliver, to our users and to fellow developers. If speed becomes a challenge, we either cut the scope or fix the underlying issue.
Be curious
The field of DataFrames is big, covering many subdomains, and no one has all the answers. Staying curious, asking questions, and keeping an open mind is how you learn and grow quickly here.
Health
We're all human. The wellbeing of our team and their work-life balance matters to us. We're in this for the long run, a sustainable, productive relationship.
Trust
We have confidence in our teammates to make the right calls. In return, we take on responsibility, knowing others depend on us just as we depend on them. We honor our commitments.
