Do you like your code to be as tight and optimized as it can be? Do you have deep knowledge of the Java language and how its internals work? Do you love writing code used by millions of developers or maybe you already have experience writing structural or common code in popular libraries? The Amazon Corretto team is looking for engineers to work on the JDK libraries, improving performance and adding features to OpenJDK.
As a member of the team, you will have the opportunity to contribute to Corretto, OpenJDK, and successfully running Amazon and AWS customers' services. As a JDK developer on the Corretto team, you will work closely with application owners to identify opportunities for improving and optimizing the JDK, based on real-world usage and performance data. You will help to set the direction in which to work, proposing ideas and developing proofs-of-concept that demonstrate where the benefits lie. To do this effectively, you will be diving into potentially new areas of the JDK to learn how they work in detail. You will also work in the open with the OpenJDK and Corretto communities to bring as many improvements as possible to upstream OpenJDK for the benefit of all Java developers and application owners.
About the team
Amazon Corretto is Amazon's distribution of OpenJDK, used to run our thousands of Java services and also deployed by many AWS customers. The Corretto team is focused on improving OpenJDK for all Java users by focusing on performance, particularly on ARM64 as used by AWS' Graviton range of processors, and features like the Generational Shenandoah garbage collector. We work with the community to help maintain the Long-Term Supported (LTS) versions of OpenJDK as well as contribute to the bleeding edge. We are looking to expand the Corretto team to participate even more in the community and contribute to the long-term success of OpenJDK as a platform.
While Corretto is a relative newcomer to the scene, our team is composed of OpenJDK Authors, Committers, and Reviewers, some with decades of experience in JDK, languages, compilers, and managed runtimes. We learn about where to invest in OpenJDK from running some of the world's largest Java services. We are firm believers in Open Source and are looking for like-minded people who are interested in working in the open with the community.
EVEN IF YOU ONLY MEET SOME OF THE REQUIREMENTS, OR BELIEVE YOU AREN'T EXPERIENCED ENOUGH, WE ARE STILL INTERESTED IN HEARING FROM YOU. We believe that a solid technical foundation and a strong interest in the subject matter can make you successful on the team and we have the opportunities to help you learn and grow in this space. Knowledge and experience in related technologies are generally applicable and valuable.
Java is used for the majority of services in Amazon and nearly all public-facing AWS services. Because of this, we have a vested interest in running the best-possible JDK in areas like security and performance. In 2018, the AWS JDK team migrated Amazon's default JDK to OpenJDK. In order to do this we built rigorous security and quality mechanisms around OpenJDK. We are now able to apply security and Amazon custom patches to the internal OpenJDK as soon as they're available. In early 2019, we took this work public and launched Amazon Corretto, our distribution of OpenJDK. With Corretto, we make our work on OpenJDK available to our customers and the OpenJDK community at large.
