Data Scientist

Role Description

Mercor is hiring on behalf of a leading AI research lab to bring on a highly skilled

Data Scientist

with a

Kaggle Grandmaster profile.

In this role, you will transform complex datasets into actionable insights, high-performing models, and scalable analytical workflows. You will work closely with researchers and engineers to design rigorous experiments, build advanced statistical and ML models, and develop data-driven frameworks to support product and research decisions.

What You’ll Do

Analyze large, complex datasets to uncover patterns, develop insights, and inform modeling direction

Build predictive models, statistical analyses, and machine learning pipelines across tabular, time-series, NLP, or multimodal data

Design and implement robust validation strategies, experiment frameworks, and analytical methodologies

Develop automated data workflows, feature pipelines, and reproducible research environments

Conduct exploratory data analysis (EDA), hypothesis testing, and model-driven investigations to support research and product teams

Translate modeling outcomes into clear recommendations for engineering, product, and leadership teams

Collaborate with ML engineers to productionize models and ensure data workflows operate reliably at scale

Present findings through well-structured dashboards, reports, and documentation

Qualifications

Kaggle Competitions

Grandmaster

or comparable achievement : top-tier rankings, multiple medals, or exceptional competition performance

3–5+ years of experience in data science or applied analytics

Strong proficiency in Python and data tools (Pandas, NumPy, Polars, scikit-learn, etc.)

Experience building ML models end-to-end : feature engineering, training, evaluation, and deployment

Solid understanding of statistical methods, experiment design, and causal or quasi-experimental analysis

Familiarity with modern data stacks : SQL, distributed datasets, dashboards, and experiment tracking tools

Excellent communication skills with the ability to clearly present analytical insights

Nice to Have

Strong contributions across multiple Kaggle tracks (Notebooks, Datasets, Discussions, Code)

Experience in an AI lab, fintech, product analytics, or ML-focused organization

Knowledge of LLMs, embeddings, and modern ML techniques for text, images, and multimodal data

Experience working with big data ecosystems (Spark, Ray, Snowflake, BigQuery, etc.)

Familiarity with statistical modeling frameworks such as Bayesian methods or probabilistic programming

Why Join
