Descripción del empleo

Please submit your CV in English and indicate your level of English proficiency.

Mindrift connects specialists with project-based AI opportunities for leading tech companies, 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 (days/weeks)
• 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 good fit for ML specialists with an experience in python open to part‑time, non‑permanent projects. Ideally, contributors will have:

• 5+ years of hands‑on machine learning experience with proven business impact
• Portfolio of completed projects and publications showcasing real‑world problem‑solving
• Expert Python programming for data science (pandas, numpy, scipy, scikit‑learn, statsmodels)
• Expert statistical analysis and machine learning - deep understanding of algorithms, methods, and their practical applications
• Expert with 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+)
