This is your role 

In this role, you work on the backbone of our DevEx platform. You improve the tools and services that our engineering teams use every day by managing and developing core engineering tools such as GitHub, JFrog Artifactory, SonarQube and GitHub Copilot. You make these tools stable, secure and easy to use. You also create and maintain integrations and automations that reduce manual work and help teams deliver software faster, safer and with more confidence. 

You shape our DevEx platform so engineers can adopt AI Coding in a secure and practical way. You set and operate guardrails that support cloud and code delivery. You expand self‑service options for onboarding, access and provisioning. You also build automated compliance checks to keep the toolchain reliable and auditable.
