Company Overview

Fact Set creates flexible, open data and software solutions for over 200,000 investment professionals worldwide, providing instant access to financial data and analytics that investors use to make crucial decisions.

Fact Set's values are the foundation of everything we do. They express how we act and operate, serve as a compass in our decision‑making, and play a big role in how we treat each other, our clients, and our communities.

As a member of our Release Infrastructure team, you’ll own critical infrastructure, including Git Hub, Sourcegraph, Sonar Qube, Artifactory, and AI‑powered coding assistants. These tools directly accelerate the delivery of innovative workflow solutions to buy‑side, sell‑side, and wealth‑management clients.
