Data Scientist

Role Overview

A data scientist uses data, statistics, and programming to help projects make better decisions and build predictive models that solve our clients’ problems. The data scientist works across the full data lifecycle, from collecting raw data to communicating insights to stakeholders in clear, actionable ways.

What You Will Do

Work with stakeholders to understand business problems and define data-driven questions to answer. Collect, clean, and transform large structured and unstructured datasets from multiple sources. Explore data to find patterns, trends, and anomalies using statistical analysis and visualization. Build, evaluate, and deploy machine learning and statistical models to make predictions or automate decisions. Communicate findings through dashboards, reports, and presentations to both technical and non-technical audiences.

Why It Might Be a Fit

This role requires strong proficiency in Python, ability to design, train, evaluate, and operationalize ML models at production scale, and a strong grasp of probability theory, random variables, common distributions, expectation, variance, and covariance.

Requirements

• 5+ years of experience in data science or applied ML roles
• Experience owning end-to-end analytics from discovery to modeling to storytelling to implementation
• Experience working with large, complex datasets across multiple sources
• Strong proficiency in Python
• Ability to design, train, evaluate, and operationalize ML models at production scale
• Strong grasp of probability theory, random variables, common distributions, expectation, variance, and covariance
• Solid training in estimation and inference: confidence intervals, likelihood, maximum likelihood estimation, and Bayesian basics
• Ability to choose appropriate statistical techniques for messy, real-world data and explain trade-offs, limitations, and uncertainties
• Track record of translating statistical findings into clear, decision-ready narratives and recommendations for stakeholders
• Ability to stay current with new methods and tools and apply them thoughtfully to real-world problems
• Ability to create compelling visualizations (Tableau, Looker, matplotlib, Plotly) that clearly communicate patterns, trends, and insights to both technical and non-technical audiences
• Mastery of probability theory, statistical inference, linear algebra, and optimization
• Extensive experience designing and interpreting experiments (including A/B tests and causal inference methods such as DiD, IVs, and matching)
• Strong intuition for model assumptions, uncertainty, and bias/variance tradeoffs; fluency with a broad range of statistical and machine-learning models and diagnostics
