Organization

Company: Alignerr

Position: Data Science Expert – AI Content Specialist

Type: Hourly Contract

Compensation: $40–$80 /hour

Location: Remote

Commitment: 10–40 hours/week

What You’ll Do

• Develop complex problems: design advanced data science challenges across domains like hyperparameter optimization, Bayesian inference, cross‑validation strategies, and dimensionality reduction.
• Author ground‑truth solutions: create rigorous, step‑by‑step technical solutions—including Python/R scripts, SQL queries, and mathematical derivations—that serve as “golden responses.”
• Technical auditing: evaluate AI‑generated code (using libraries such as Scikit‑Learn, PyTorch, or TensorFlow), data visualizations, and statistical summaries for technical accuracy and efficiency.
• Refine reasoning: identify logical fallacies in AI reasoning—such as data leakage, overfitting, or improper handling of imbalanced datasets—and provide structured feedback to improve the model’s “thinking” process.

Requirements

• Advanced degree: Master’s (pursuing or completed) or PhD in Data Science, Statistics, Computer Science, or a quantitative field with a heavy emphasis on data analysis.
• Domain expertise: strong foundational knowledge in core areas such as supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP.
• Analytical writing: the ability to communicate highly technical algorithmic concepts and statistical results clearly and concisely in written form.
• Attention to detail: high level of precision when checking code syntax, mathematical notation, and the validity of statistical conclusions.
• No AI experience required.

Preferred

• Prior experience with data annotation, data quality, or evaluation systems.
• Proficiency in production‑level data science workflows (e.g., MLOps, CI/CD for models).

Why Join Us

• Excellent compensation with location‑independent flexibility.
• Direct engagement with industry‑leading LLMs.
• Contractor advantages: high agency, agility, and international reach.
• More opportunities for contracting renewals.
