Software Engineer: Senior CPython Core Developer

Quansight is looking to find a full-time remote CPython core developer to join our team of data science and engineering professionals and open source maintainers and experts. We are also open to a part-time or contracting role.

What you’ll do

A core part of this position will involve contributing to CPython and helping improve and maintain CPython itself and other key open source projects in the Python ecosystem, with an initial focus on improving free-threading in CPython.

In this position, you’ll get to:

• Contribute to CPython and other important open-source projects
• Use C, C++, Python, compiler technology, Python C API binding generators, and possibly other languages like CUDA, Rust, and Cython
• Work with modern numerical computing and deep learning technology
• Develop new features, work on performance enhancements and help maintain code with millions of users
• Drive fruitful conversations around technical issues, engineering practices, and community processes, and suggest improvements and ideas as you encounter them
• Review code and provide thoughtful, constructive feedback during code reviews
• Interact with community members and with clients from both industry and academia
• Collaborate with, learn from, and mentor team members
• Be a part of the Python community

For this role, you must already be part of the CPython core development team and have in-depth knowledge of CPython internals and usage of the CPython C API. We also highly value good communication skills. Knowledge of numerical computing and deep learning is beneficial but not required.
