Data Science Expert — AI Content Specialist
About The Role
What if your deep knowledge of machine learning, statistics, and data engineering could directly shape the intelligence of tomorrow's AI systems? We're looking for Data Science Experts to challenge, evaluate, and improve cutting-edge language models — exposing their blind spots and helping them reason more rigorously about complex technical problems.
This is a fully remote, flexible contract role designed for data science professionals who want to do meaningful, intellectually stimulating work on their own schedule.
Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
- Design Advanced Challenges — Craft complex, domain-spanning data science problems covering topics like 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 definitive benchmarks for AI evaluation
- Audit AI-Generated Code — Critically evaluate model outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow, assessing them for correctness, efficiency, and technical soundness
- Refine Model Reasoning — Identify logical failures in AI outputs — such as data leakage, overfitting, or mishandled class imbalance — and provide structured feedback that directly improves how these models think and respond
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Who You Are
- Holds or is pursuing a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
- Strong foundational expertise in core data science domains: supervised/unsupervised learning, deep learning, big data technologies (Spark, Hadoop), or NLP
- Able to communicate complex algorithmic and statistical concepts clearly and precisely in writing
- Exceptionally detail-oriented when reviewing code syntax, mathematical notation, and statistical conclusions
- No prior AI or annotation experience required — your domain expertise is what matters
