Cephalgo is hiring a Freelance Machine Learning Engineer

About the Role

Freelance Machine Learning Engineer to design and develop computational STEM problems requiring Python programming and non-trivial reasoning for AI testing and evaluation at Mindrift. This is a project-based role with flexible weekly hours, not permanent employment.

What You'll Do

  • 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're Looking For

  • 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+)

Technical Stack

Python, Numpy, Pandas, Scipy, scikit-learn, statsmodels, SQL, TensorFlow, PyTorch, LangChain, LLMs, RAG, prompt engineering, vector databases

Benefits & Compensation

  • Project-based work with leading tech companies
  • Opportunity to work on AI testing, evaluating, and improving AI systems

Compensation: $58 per hour equivalent. Compensation varies across projects depending on scope, complexity, and required expertise.

Work Mode

Tasks estimated at 10–20 hours per week during active phases; not a guaranteed workload. Fully remote with global availability.
