Deep Dive into Evaluation Areas

Key Responsibilities

As a Data Analyst at Healthfirst, your primary responsibility is to transform raw data into insights that improve business operations and member care. On a daily basis, you will write and execute SQL queries to extract data from our warehouses, perform deep-dive analyses to identify trends, and build visualizations that make your findings easy to understand for executive leadership.

You will act as a strategic partner to various departments. For instance, you might work with the Clinical team to analyze the effectiveness of a new care management program or collaborate with the Finance team to forecast medical spend. Your role involves a high degree of collaboration; you aren't just sitting behind a screen, but actively participating in meetings to explain your data and help shape the next steps of a project.
