  6. Review and validate peer-contributed code and technical submissions for accuracy and clarity.

Preferred Qualifications

  1. Significant hands-on expertise in at least one of the following: Python3, Java, Rust, Go, C++, or TypeScript.

  2. Deep understanding of algorithms, data structures, and software engineering principles.

  3. Proven ability to debug complex systems, resolve bugs, and deliver effective optimizations.

  4. Experience with large codebase refactoring and legacy system modernization.

  5. Track record of delivering high-impact features from conception through delivery within cross-functional projects.

  6. Strong documentation and communication skills to articulate technical concepts clearly.

  7. Interest in or curiosity about AI and its technical challenges (previous AI experience not required).
