Job Description

Oracle Linux group

Oracle's Linux team develops on and contributes to upstream Linux to support our engineered system as well as Oracle's Cloud infrastructure. Our team patches and enhances the Linux kernel and promotes the adoption of Linux at Oracle and in the industry in general. Developers in this role are expected to be active contributors to upstream Linux.

Through our experience with engineered systems such as the flagship Exadata, we created an additional kernel option, the Unbreakable Enterprise Kernel. Supporting engineered systems required us to be more innovative and modern with the Linux kernel, and UEK is a Linux kernel which combines mainline Linux performance with enterprise stability. UEK has secured world record database benchmarks for Oracle and provides the fastest execution environment for Oracle products. This kernel is refreshed from upstream Linux every 18 months, ensuring that new features can be used by these products in a timely fashion.

Oracle Linux was created in 2006 to provide a Linux solution which was well-tested for enterprise products such as the Oracle Database, Middleware and applications, coupled with enterprise-level support. Oracle has been an active contributor to Linux since 1998, shipping the first ever commercial database on Linux and contributing multiple filesystems and feature enhancements. Our core focus is developing open-source products and improving the stability and performance of the OS. Most projects for our team are in C, python, and bash shell. Projects initiated or led by Oracle include core Linux components: btrfs, the next generation Linux filesystem; OCFS2, a general-purpose filesystem; t10 DIF, enforcing data integrity throughout the IO stack; and RDS, a reliable datagram socket replacement for UDP on Infiniband fabrics. A comprehensive listing of our open-source contributions can be found on and .

Linux Sustaining Engineering (LSE)

We are responsible for all production software that is part of Oracle Linux, from the kernel to userspace. LSE is a tight-knit team of hard working senior engineers that aren't afraid to cross competencies and help each other out. We work closely with other development and sustaining organizations within Oracle as well as engaging with external partners, and are frequently recognized for our work.
