DotNet Compiler Developer

Introduction

Are you interested in compilers and debuggers, operating systems development and Open Source? Your favourites are Linux and low-level programming? Would you like to work with Open Source communities, and do you intend to build up a reputation as an Open Source maintainer? If so, our team is the right place for you!

Our compilers and toolchain team is responsible for enhancing and maintaining DotNet, GoLang, OpenJDK and Debian compilers, debuggers, libraries, tools, test automation &

CI/CD). We tightly collaborate with the international development teams of IBM, the global maintainers of Open Source communities, and our Linux distribution partners (Red Hat, SUSE, Canonical).

Our focus is on the support of the IBM Z / Linux ONE architecture.

Linux on IBM Z / LinuxONE forms the basis of many of IBM's commercial solutions in Cloud, Analytics and AI
