Alignerr Corp.; Sheffield (TX); Remote; USD 83,000 - 165,000; Full time

Job summary

Alignerr is seeking a Data Science Expert to challenge, evaluate, and improve cutting-edge AI models in a fully remote, asynchronous setting. This contract role suits data scientists, researchers, and quantitative professionals looking for high-impact work.

You will design advanced challenges, author ground-truth solutions, audit AI-generated code, and sharpen AI reasoning. Master's or PhD in a quantitative field is required or in progress, with strong ML, NLP, and big data expertise.

Qualifications

• Holds a Master's (pursuing or completed) or PhD in Data Science, Statistics, Computer Science, or a related quantitative field.
• Strong foundational expertise in supervised/unsupervised learning, deep learning, NLP, or big data technologies (Spark, Hadoop).
• Able to communicate complex algorithmic and statistical concepts clearly in writing.
• Precise and detail-oriented when reviewing code syntax, mathematical notation, and statistical conclusions.
• Self-motivated and comfortable working independently in an async, task-based environment.
• No prior AI or annotation experience required.

Responsibilities

• 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 reference solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as the gold standard for AI evaluation
• Audit AI-Generated Code — Evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for technical correctness, efficiency, and best practices
• Sharpen AI Reasoning — Identify logical failures in AI-generated analysis — such as data leakage, overfitting, or mishandled class imbalance — and provide structured feedback that improves how models think and respond
