Open Source Linux AI Library Developer

Responsibilities
This position is for an experienced Linux GNU/Open Source AI Library developer who has experience developing, optimizing and tuning code to a specified Hardware Architecture. While the target architecture of this work will be the IBM POWER architecture, experience tuning to x86 or ARM architectures will be directly applicable. As a developer on the Linux on Power team you will be responsible for:

Working with and interlocking with other internal teams and with the Open Source Community for defining, designing, developing and testing Linux on Power specific features in the various AI libraries and framework like OpenBlas, ONNXRuntime, Pytorch , Tensorflow, FAISS and Eigen. Ensuring that those features are accepted upstream and incorporated into the appropriate Linux distributions.

In addition to design and development work you will be responsible for working issues and defects including problem determination, problem recreation, providing fixes, validating fixes and getting fixes accepted by the Community. Developers in this position are required to assist with resolving customer critical situations, for assisting with or leading proof of concepts and for providing technical guidance and consulting for pre-sales and post sales engagements.

This role requires expertise with the POWER instruction architecture and Linux based OS. Familiarity with software builds, bring-up, test and performance analysis tools used by Linux on Power is desirable along with general hardware skills. Applicant will be engaged in performance analysis and tuning utilizing the POWER instruction profiling tools. Candidates must have the ability to work in a team based environment with global and remote team members.

Candidate should have experience with C/C++, scripting languages, assembler, familiarity with Bugzilla, GIT, open source development tools, simulation tools, performance analysis tools and working with mailing lists.
