Remote Data Science Expert for AI Content & Benchmarking

Alignerr Corp.; United States; Remote; AUD 83,000 - 165,000; Part time

Job summary

Alignerr is seeking a Data Science Expert – AI Content Specialist for a remote hourly contract. You will craft rigorous data science challenges and develop expert solutions with Python/R, SQL, and mathematical derivations to benchmark AI responses.

You will audit AI-generated code using Scikit-Learn, PyTorch, and TensorFlow, and refine AI reasoning by identifying data leakage, overfitting, and class-imbalance issues. Strong writing and precise analysis are essential.

Qualifications

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

Responsibilities

• 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 TensorFlow 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
