Data Science Expert – AI Content Specialist About The Role

• Organization:
  Alignerr
• Type:
  Hourly Contract
• Location:
  
  Remote
• Commitment: 10-40 hours/week

• Design Advanced Challenges
  - Create rigorous data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
• Author Ground-Truth Solutions
  - Develop step-by-step expert solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as the definitive benchmark for AI responses
• Audit AI-Generated Code
  - Evaluate code written using libraries like Scikit-Learn, PyTorch, and Tensor Flow for correctness, efficiency, and best practices
• Refine AI Reasoning
  - Identify flaws in AI logic - such as data leakage, overfitting, or mishandled class imbalance - and provide structured feedback that improves model reasoning at a fundamental level
• Document Failure Modes
  - Surface and record how AI models break down on complex technical topics so research teams can harden model performance

• Holds or is pursuing a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
• Strong foundational knowledge across supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP
• Able to communicate complex algorithmic concepts and statistical results clearly and concisely in writing
• Highly precise - you catch errors in code syntax, mathematical notation, and statistical conclusions that others miss
• Self-motivated and reliable when working independently on task-based assignments
• No prior AI or annotation experience required

• Experience with data annotation, data quality assurance, or evaluation systems
• Familiarity with production-level data science workflows - MLOps, CI/CD pipelines for models, or model monitoring
• Prior work auditing or benchmarking machine learning systems

• Work directly with industry-leading AI research labs on cutting-edge model development
• Fully remote and asynchronous - work when and where it suits you
• Freelance autonomy with consistent, intellectually rewarding task-based work
• Contribute to AI that will influence how advanced models reason about data science for years to come
• Potential for ongoing work and contract extension as new projects launch
