Posit (formerly RStudio) creates software that helps people understand data and make better decisions in real-world applications. Our core offering is an open-source data science toolchain used by millions worldwide, and we aim to make it available to everyone, regardless of their economic means. We’re a Certified B Corporation®, which means we’ve written our open-source mission into our corporate charter. Our commercial products support this work, which helps data scientists manage their work and share the results with others.

About the Open Source group

The Open Source group aims to provide a seamless end-to-end data science experience and to help data scientists learn the software engineering skills they need. We develop and maintain open source packages for data science and scientific communication, including R packages like the tidyversetidymodelsShiny for R and Python, and Quarto. The goals of the Open Source group are not only to provide a seamless end-to-end experience but also to help users learn and flourish. This involves developing and disseminating documentation and fostering a welcoming community. We value kindness, humility, openness, and resourcefulness in our work and interactions with the community and each other.

About the role

The Guild AI development team is a small group delivering a powerful solution to help machine learning engineers get the most from their models.  At its core Guild AI is an experiment tracking system that builds “runs” seamlessly during the model development process.  The system encapsulates everything engineers need to understand, optimize and recreate their work.  Guild includes the ability to tune hyperparamers, train and backup models remotely, compare and analyze runs and automate pipelines.

Guild AI is fully open-source and is built to be highly configurable.  Guild AI seeks to work with machine learning engineers existing workflows without needing custom code to enable it.

Our developers have high autonomy. They are highly product focussed and are responsible for the full development lifecycle, including triaging GitHub issues, implementing changes, writing documentation, testing code, and interacting with the broader community. Posit is a remote-first organization, and Open Source has engineers in 10 countries spanning 10 time zones.
