Data Scientist (Masters) — AI Data Trainer
About The Role
What if your expertise in machine learning, statistical modeling, and data engineering could directly shape how the world's most advanced AI systems reason and solve problems? We're looking for experienced data scientists to challenge, audit, and improve cutting-edge AI models — pushing them to their limits and making them smarter in the process.
This is a fully remote, flexible contract role. No prior AI industry experience required — just deep, proven knowledge of data science and a sharp eye for technical precision.
Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
Design Advanced Challenges: Develop rigorous, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
Author Ground-Truth Solutions: Write precise, step-by-step technical solutions — including Python/R scripts, SQL queries, and mathematical derivations — that serve as authoritative reference answers
Audit AI-Generated Code: Evaluate AI-produced code using libraries like Scikit-Learn, PyTorch, and TensorFlow for technical accuracy, efficiency, and correctness
Refine AI Reasoning: Identify flaws in model reasoning — such as data leakage, overfitting, or mishandled class imbalance — and provide structured, actionable feedback to improve how AI thinks through problems
Document Failure Modes: Systematically record model shortcomings across areas like neural network architecture, statistical inference, and data engineering pipelines
Who You Are
Currently pursuing or holding a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
Deeply knowledgeable in core data science domains: supervised/unsupervised learning, deep learning, NLP, big data technologies (Spark, Hadoop), or similar
Able to communicate complex algorithmic concepts and statistical results clearly and precisely in writing
Meticulous when checking code syntax, mathematical notation, and the validity of statistical conclusions
Self-directed and reliable — comfortable working independently on technical tasks without hand-holding
No prior AI training or annotation experience required
Nice to Have
Prior experience with data annotation, data quality evaluation, or model evaluation systems
Familiarity with production-level data science workflows — MLOps, CI/CD for models, or similar
Experience reviewing or auditing technical work in academic or professional settings
