We partner with divisional DevOps/TechOps teams and Information Security (InfoSec) to establish consistent controls and governance across the software development lifecycle (SDLC). As a globally distributed team, we build services, policies and automated controls that secure the developer toolchain while keeping platforms simple, consistent and engineer friendly.  The Impact  You will embed security governance into the software delivery lifecycle by translating requirements into clear policies and automated controls. Your work will protect source control, CI/CD pipelines, build infrastructure and the software supply chain without creating unnecessary friction for engineers. You will strengthen credentials, secrets and non-human identity governance; drive security findings through to remediation; and contribute to AI-assisted development governance and developer endpoint security. Working with platform teams, divisional DevOps/TechOps teams and Business Information Security Officers (BISOs), you will support audit and compliance and make secure practices the default across S&P Global.  What’s in It for You  Help shape how thousands of engineers build and ship software securely.
