Data Scientist (Masters)

AlignerrMelbourneRemoteContract1 week ago

Alignerr seeks Masters-level data scientists to design complex data science challenges, author ground-truth solutions, and audit AI-generated code to improve advanced AI models. This is a fully remote, flexible hourly contract role requiring deep expertise in machine learning, statistical inference, and data engineering, with no prior AI industry experience needed.

What you'll do

Design Advanced Challenges — Create complex, domain-spanning data science problems covering hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more — tasks that genuinely stress-test AI reasoning
Author Ground-Truth Solutions — Produce rigorous, step-by-step technical solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as authoritative "golden responses"
Audit AI-Generated Code — Evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow, assessing technical accuracy, efficiency, and correctness
Refine AI Reasoning — Identify logical failures in AI outputs — data leakage, overfitting, mishandled class imbalance — and deliver structured feedback that improves how models think through data problems
Document Failure Modes — Systematically record how and why advanced language models fail on technical tasks, contributing directly to model hardening efforts
