Senior Full Stack Software Development Engineer

We're building a world of health around every individual - shaping a more connected, convenient and compassionate health experience. At CVS Health®, you'll be surrounded by passionate colleagues who care deeply, innovate with purpose, hold ourselves accountable and prioritize safety and quality in everything we do. Join us and be part of something bigger - helping to simplify health care one person, one family and one community at a time.

We are hiring a Senior Full Stack Software Development Engineer with strong React and Python (with .NET as a nice-to-have) experience to join our Data Engineering team. You will serve as a key senior contributor, driving the end-to-end development of a new, critical internal self-service application. Your work on this software solution will be instrumental in our initiative to modernize how data is accessed and managed, enabling teams across the company to more easily work with their own data through the user-friendly tools you build.

This project involves a shift from traditional data handling processes, with your primary focus being on creating a robust application that empowers this new approach to data accessibility and decentralized ownership.

This is a high-impact, high-autonomy role suited for a detail-oriented and collaborative individual who thrives on ownership, knows how to apply best practices, and can independently design, build, and maintain production-grade software. While you'll be leveraging your core software engineering expertise, you'll also be at the forefront of our data modernization, gaining deep insights into modern data architectures and practices by building the tools that enable them.

You will have access to AI tooling to assist in all aspects of the SDLC.

You will build a solution that provides these capabilities and more to our engineering and analytics teams.

Data Self-Service Platform

The Data Self-Service Platform initiative addresses critical challenges in our current data operations. You will build a suite of tools that centralizes data quality and empowers analytics teams to drive insights. Specifically, you will develop a Self-Service Data Quality Platform that enables engineering and analytics teams to monitor pipelines, set up alerts, and maintain data integrity. Additionally, you will build an AI-powered analytics platform that allows analytics teams to automatically generate semantic layers and data models for use by analytic agents, accelerating time-to-insight and reducing manual dependencies.
