What if your expertise in machine learning, statistical inference, and data engineering could directly shape how the world's most advanced AI systems reason and respond?
We're looking for experienced data scientists to challenge, audit, and improve cutting-edge AI models — pushing them to their limits, exposing their blind spots, and building the gold-standard solutions that make them smarter. This is a fully remote, flexible contract role where your deep technical knowledge does meaningful work at the frontier of AI development.
Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
Design Advanced Challenges — Create complex, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
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 benchmark for AI responses
Audit AI-Generated Code — Evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for technical accuracy, efficiency, and correctness
Sharpen AI Reasoning — Identify logical failures in AI outputs — data leakage, overfitting, improper handling of imbalanced datasets — and deliver structured feedback that improves model reasoning
Document Failure Modes — Stress-test model responses across ML theory, statistical inference, neural network architectures, and data engineering pipelines, capturing every gap so models can be hardened
Who You Are
Pursuing or holding a Master's or PhD in Data Science, Statistics, Computer Science, or a quantitative field with a strong emphasis on data analysis
Strong foundational knowledge in supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP
Able to communicate complex algorithmic concepts and statistical results clearly and precisely in writing
Detail-oriented — you catch errors in code syntax, mathematical notation, and statistical conclusions that others miss
Self-directed and reliable when working independently on technical tasks
No prior AI industry experience required
Nice to Have
Prior experience with data annotation, data quality assurance, or model evaluation systems
Proficiency in production-level data science workflows — MLOps, CI/CD for models, experiment tracking
Familiarity with prompt engineering or AI benchmarking methodologies
