Performance Engineer- Golang

Introduction
Are you interested in 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 Linux development team is responsible for enhancing and maintaining the full stack (Linux kernel
and its device drivers, libraries, tools, compilers, debuggers, virtualization (KVM) , test automation &
CI/CD). We tightly collaborate with the international development teams of IBM (e.g. hardware and
firmware development), 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,
e.g. new processor instructions, new I/O attachments (PCIe, NVMe, Ethernet, RDMA etc.) and
accelerators for cryptographic functions.
Linux on IBM Z / LinuxONE forms the basis of many of IBM’s commercial solutions in Cloud, Analytics and AI.”
