Senior Open-Source Python Engineer (ML Developer Tools)

• You’ll join the Applications team, whose goal is to build the tooling that helps developers create machine learning applications on top of the primitives we offer on the Hub: Gradio, Spaces , Inference Providers, Datasets, Xet, and more
• Concretely, that means maintaining and growing libraries like Trackio, a local-first, agent-friendly experiment tracking platform, FastRTC, our library for real-time audio and video streaming in Python, and Gradio itself, used by more than 1 million developers each month
• These tools have made machine learning accessible to a wide audience — for the first time in history, anyone with an internet connection can use cutting-edge models right from their browser
• Several of these libraries are still early in their life, and new ones will start from scratch. A large part of this role is taking a project from its first users to widespread adoption: shaping the API, shipping fast, and getting it into developers’ hands
• Designing, developing, and maintaining core features across the team’s libraries, ensuring scalability, reliability, and ease of use for ML developers
• Architecting complex Python projects and frameworks that serve as foundational tools for the ML community
• Growing early-stage libraries: defining the API surface, writing the demos and documentation that make them click, and driving adoption in the developer community
• Working on real-time streaming and networking capabilities, a core priority for Gradio 7 and beyond
• Collaborating with open-source contributors and engaging with the broader community through code reviews, discussions, and support
• Integrating modern frontend technologies to create seamless and intuitive user experiences for Python-based web applications
• Adapting to evolving engineering challenges and contributing to the direction of our developer tools as the landscape changes
