IntroductionAre you interested in operating systems development and Open Source? Your favorites are Linux and low-level programming? Would you like to be part of an Open Source community, 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 the Linux kernel for IBM Z / IBM LinuxOne including its device drivers, libraries, tools, compilers, debuggers, virtualization (KVM) and 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 / LinuxONE architecture, e.g. new processor instructions, new I/O attachments (PCIe, NVMe, Ethernet, RDMA etc.) and accelerators for AI and cryptographic functions. Linux on IBM Z / LinuxONE forms the basis of many of IBM's commercial solutions in Cloud, Analytics, Finance, and AI.
Your Role and ResponsibilitiesAs a key member of our dynamic team, you will play a vital role in crafting exceptional software experiences. Your responsibilities will comprise of design and specifications for new enhancements, coding, problem determination and bug fixing, performance analysis, submitting your code to upstream community repositories, and solving client problems. Your attendance at Open Source community meetings is recommended and supported, and client facing activities (e.g. client support, providing lectures at conferences) are possible. You will closely interact with the respective Open Source communities ("upstream integration" of your code) and our distribution partners (Red Hat, SUSE, Canonical).
PLEASE NOTE - This position is based in our Waterford location and requires working onsite 3 days per week.
