Who We Are

In a digital economy data is the 21st century gold rush. Imagine working for a Big Data company with 10 Petabytes of data at your fingertips. A company where Analysts and Scientists derive insights from 35+ Terabytes of new data every week.

84.51° is a wholly owned subsidiary of The Kroger Company. Our data is sourced from consumer transactions and behavior across 24 banners, 38 states and 62 Million households. We are the research, development and innovation arm of the Nation’s second largest retailer.

Analysis

We are a community of analysts – we are researchers in search of the customer story. We are the voice of the customer. Customers share their story with us each and every day, and it is our job to tell their story. Our Analysis team is known for solving client and customer problems, employing the most appropriate statistical and mathematical analytic approaches.

We expect all analysts to be hands on with respects to the analysis of a retailer database, using the full suite of 84.51° technical tools – SAS, SQL, R, Excel, and other specific internal tools – to create timely, relevant, and actionable insights.

General Description

The Research Scientist will employ skills and experience to improve, create and innovate data-driven modeling approaches for our price and promotion solutions, while anticipating and charting future research needs.
