Continued technological advances are always on the horizon.

Java Platform Group The Java Platform Group (JPG) is the team primarily responsible for building and advancing the Java platform, developing the Java language, and stewarding the OpenJDK ecosystem forward. For many years, JPG has ensured that Java remains relevant in the technology universe by developing new features and addressing the problems and opportunities of tomorrow. With over 60 billion active JVMs globally, much of the world relies on the work of this team - Java innovation starts here.

While we act with the speed and attitude of a start-up, we operate with the scale and customer-focus expected as the leading enterprise software company in the world. We strive for equity, inclusion, and respect for all, ensuring our unique individuality is harmonious in a team environment. As an intern, you will be part of a team of uniquely smart, motivated, and diverse people who are offered the autonomy and support to do their best work, while also being given the opportunity to learn.

JVM Compiler Team The Java Virtual Machine is a core component of the Java SE platform. It implements the Java Virtual Machine Specification, and is delivered as a shared library in the Java Runtime Environment. As the Java bytecode execution engine, it provides Java runtime facilities, such as thread and object synchronization, on a variety of operating systems and architectures. It efficiently manages the Java heap using garbage collectors, optimized for both low pause time and throughput. It provides data and information to profiling, monitoring and debugging tools and applications.

The Compiler Team is responsible for development and maintenance of the Virtual Machine's just-in-time (JIT) compilers that adaptively compile Java bytecodes into optimized machine instructions. The team works hard to ensure high performance on all supported platforms and stays up-to-date on current and future hardware. Feature development projects to take advantage of new hardware features and to increase stability and performance are always part of the team's focus. The team is also deeply involved in work for ongoing and future key JDK projects including Projects Valhalla, Loom, Panama and ZGC.
