• Demonstrated ability to debug software, fix complex issues, and implement new features.
• Strong understanding of algorithms, data structures, and fundamental computer science concepts.
• Experience with automated testing, code reviews, and performance optimization.
• Strong analytical thinking, problem-solving, and technical communication skills.

Preferred Qualifications

• Significant hands-on experience in at least one supported programming language: Python, Java, Rust, Go, C++, or TypeScript.
• A strong record of open-source contributions, preferably demonstrated through a GitHub profile.
• Experience refactoring large codebases and modernizing legacy systems.
• A track record of delivering high-quality, scalable software features.
• Experience identifying system bottlenecks and improving application performance.
• Strong documentation skills and an interest in AI development.

Compensation & Engagement

• Compensation: $50–$100/hour equivalent, with payment based on tasks that meet project specifications.
• Engagement: Contractor role with flexible remote work.
• Workload: Approximately 15 hours per task run, with minimum weekly submission requirements.
