Remote Data Scientist — AI Model Evaluator & Trainer (Masters)

Alignerr Corp.; Brisbane; Remote; AUD 55,000 - 110,000; Part time

Job summary

Alignerr is seeking a Data Scientist with a Masters to challenge, evaluate, and sharpen cutting-edge AI models. You will design complex challenges and author ground-truth solutions using Python/R, SQL, and mathematical derivations.

This fully remote contract role offers flexible hours (10–40 hours/week) and the chance to work with state-of-the-art language models, documenting failure modes and delivering actionable feedback.

Qualifications

• Pursuing or holding a Master's or PhD in Data Science, Statistics, CS, or a quantitative field.
• Strong knowledge of supervised and unsupervised learning, deep learning, big data tech (Spark/Hadoop), or NLP.
• Able to communicate complex algorithmic concepts and statistical results clearly in writing.
• Exceptionally detail-oriented and able to work independently and asynchronously.

Responsibilities

• Design Complex Challenges: Create advanced, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more — problems that genuinely push AI to its limits
• Author Ground-Truth Solutions: Develop rigorous, step-by-step technical solutions — including Python/R scripts, SQL queries, and mathematical derivations — that serve as the definitive 'golden' benchmark responses
• Audit AI-Generated Code: Critically evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and technical soundness
• Refine AI Reasoning: Diagnose logical failures in AI outputs — data leakage, overfitting, improper handling of imbalanced datasets — and deliver structured, actionable feedback that improves how models think
• Document Failure Modes: Systematically capture how and where AI reasoning breaks down across machine learning theory, statistical inference, neural network architectures, and data engineering pipelines
