Role Overview

We are looking for a Senior Statistician/Senior Data Scientist with strong hands-on experience in Python, solid statistical knowledge, and the ability to independently handle end-to-end EDA for R&D projects.


The role involves working with various types of datasets and delivering insights through clean analysis, visualizations, predictive modeling, and presentation-ready summaries.


This is a Mid-senior role where the person is expected to take ownership, work independently, and ensure high-quality, client-ready output.

Key Responsibilities

Lead end-to-end statistical analysis: data cleaning -> EDA -> statistical tests -> insights -> reports/slides.
