IntroductionAt IBM, work is more than a job – it’s a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you’ve never thought possible. Are you ready to lead in this new era of technology and solve some of the world’s most challenging problems? If so, lets talk.
Your Role and ResponsibilitiesAre 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.
What you will do :
- Your responsibilities will comprise of design and specifications for new enhancements, coding (including test automation), problem determination and bug fixing, performance analysis, and solving client problems.
- You will get opportunity to attend Open Source community meetings and will support client facing activities (e.g. client support, providing lectures at conferences).
- You will closely interact with the respective Open Source communities (“”upstream integration”” of your code) and our distribution partners (Red Hat, SUSE, Canonical).
In this job offering, we are specifically looking for a new team member to grow our toolchain
development squad (e.g. GCC, LLVM, Performance Tooling, Binutils, Valgrind, GDB, math & AI libraries).
Our toolchain team provides a wide range of different opportunities to work on low-level core Linux components. You will get the opportunity to look “under the hood” and build your skill working closely together with experienced IBM Z experts and Open Source maintainers.
Required Technical and Professional Expertise
- Experience in toolchain development and low-level programming (e.g. C, C++, Assembler)
- Experience with performance tooling (e.g. perf)
- Source code repository systems (e.g. git), scripting languages (e.g. Python) and test automation skills (e.g. Jenkins)
- Highly motivated individual to work on Enablement and Developement of new features.
- Fluent English language skills
Preferred Technical and Professional Expertise
- Prior contributions to Open Source projects or current Open Source maintainer status
- History of code reviews (e.g. on mailing lists)
- > 2 years of experience with toolchain or performance tooling development
- Experience with packing for Linux distributions
- Skills in IBM Z architecture (“”Principles of Operations””) Z assembler and I/O concepts
- -Understandstanding of Endianness
