Machine Learning Expert with Python Experience — AI Projects
hackajob is collaborating with a leading client in the AI sector to connect specialists with project-based opportunities focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment.
What this opportunity involves
While each project involves unique tasks, contributors may:
* Design original computational STEM problems that simulate real scientific workflows
* Create problems that require Python programming to solve
* Ensure problems are computationally intensive and cannot be solved manually within reasonable timeframes
* Develop problems requiring non-trivial reasoning chains and creative problem-solving approaches
* Verify solutions using Python with standard libraries (NumPy, Pandas, SciPy, scikit-learn)
* Document problem statements clearly and provide verified correct answers
What we look for
This opportunity is a great fit for ML specialists with Python experience who are open to part-time, non-permanent projects. Ideally, you will have:
* 5+ years of hands-on machine learning experience with proven business impact
* Portfolio of completed projects and/or publications showcasing real-world problem-solving
* Expert Python programming for data science (pandas, numpy, scipy, scikit-learn, statsmodels)
* Deep understanding of ML algorithms, methods, and their practical applications
* Expert-level SQL and database operations for data manipulation and analysis
* Experience with GenAI technologies (LLMs, RAG, prompt engineering, vector databases)
* Understanding of MLOps practices and model deployment workflows
* Knowledge of modern frameworks (TensorFlow, PyTorch, LangChain)
* Strong written English (C1+)
How it works Apply → Pass qualification(s) → Join a project → Complete tasks → Get paid
Time expectations Approximately 10–20 hours per week during active project phases. This is an estimate, not a guaranteed workload.
Payment
* Rates up to $55/hour
* Fixed project rate or individual rates, depending on the project
* Some projects include incentive payments
Rates vary based on expertise, skills assessment, location, and project needs. Payment details are shared per project.
