Machine Learning Engineer

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+)
