Data Science and Analytics

Job Description:

About the Role

We are looking for a Senior Analyst, Data Science to join our growing data science practice. In this role, you will lead the development and delivery of quantitative models and analyses across a portfolio of marketing clients, including predictive modeling, regression analysis, and statistical work spanning media, pricing, and promotional data. This role suits someone with 1-2+ years of hands-on analytics experience who is ready to take greater ownership of model design, client interaction, and mentorship of junior team members.

What You Will Do

Lead the build and maintenance of data science models such as Marketing Mix Models using regression-based techniques, working with weekly or monthly time-series data across media, pricing, and promotional variables.
Own data validation, cleaning, and QA processes for client-provided datasets, establishing best practices for model-ready inputs.
Run and interpret statistical analyses including adstock transformations, diminishing returns curves, and decomposition outputs, flagging issues in methodology or data quality.
Prepare and review model documentation and structured outputs (Excel workbooks, charts, summary tables) for internal and client review.
Partner directly with senior team members and clients on methodology decisions, model refinement, and results interpretation.
Mentor and review the work of junior analysts, providing feedback on code, methodology, and QA.
Drive internal tooling and process improvements as the team scales.

What We Are Looking For

1-2+ years of professional experience in analytics, data science, or a related quantitative role.
Clear, confident written and verbal communication skills, with experience presenting analytical work to stakeholders or clients.
Strong foundation in statistical modeling, particularly regression analysis and time-series methods.
Bachelor's or Master's degree in Statistics, Mathematics, Economics, Data Science, or a related quantitative field.
Proficiency in Python or R for data manipulation, modeling, and visualization (pandas, statsmodels, scikit-learn, or equivalent).
Solid understanding of concepts such as multicollinearity, heteroscedasticity, model fit diagnostics, and variable selection.
Demonstrated ability to work independently through large, messy datasets with strong attention to detail.

Nice to Have

Exposure to Bayesian methods or hierarchical modeling.
Prior experience with marketing data (media spend, impressions, GRPs) or consumer datasets.
Experience mentoring or reviewing the work of junior analysts.

What We Offer

Hands-on experience working across multiple industry verticals and client types.
A collaborative team environment with growth into more senior, client-facing responsibilities.
Exposure to the full MMM lifecycle, from data intake through to client delivery, with increasing ownership.
Competitive compensation and benefits.
