  • Create problems that require Python programming to solve.
  • Ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes (days/weeks).
  • Develop problems requiring non-trivial reasoning chains and creative problem-solving approaches.
  • Verify solutions using Python with standard libraries (numpy, pandas, scipy, sklearn).
  • Document problem statements clearly and provide verified correct answers.

Compensation

On this project, contributors can earn up to $55 per hour equivalent, depending on their level and pace of contribution.

Compensation varies across projects depending on scope, complexity, and required expertise. Please note that other projects on the platform may offer different earning levels based on their requirements.

How to get started
Simply apply to this post, qualify, and get the chance to contribute to projects aligned with your skills, on your own schedule. From creating training prompts to refining model responses, you’ll help shape the future of AI while ensuring technology benefits everyone.

  • You hold a Master’s or PhD Degree in Computer Science, Mathematics, Physics, Engineering, or a similar STEM field.
  • You have at least 5 years of Machine Learning experience with proven business impact.
  • Strong programming skills in Python (numpy, pandas, scipy, sklearn).
  • Solid understanding of numerical methods and computational algorithms.
  • Research or industry experience involving computational problem-solving.
  • Your level of English is advanced (C1) or above.
  • You are ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines.
  • Our freelance role is fully remote so, you just need a laptop, internet connection, time available and enthusiasm to take on a challenge.

Why this freelance opportunity might be a great fit for you?

  • Take part in a part-time, remote, freelance project that fits around your primary professional or academic commitments.
  • Work on advanced AI projects and gain valuable experience that enhances your portfolio.
  • Influence how future AI models understand and communicate in your field of expertise.
