Are you someone who has a desire to innovate in the language runtime space to increase performance and observability?

The JDK organisation is looking for engineers.

In 2018, the AWS JDK team migrated Amazon's default JDK to Open JDK. In order to do this we built rigorous security and quality mechanisms around Open JDK. We're now able to apply security and Amazon custom patches to the internal Open JDK as soon as they're available. In early 2019, we took this work public and launched Amazon Corretto, our distribution of Open JDK. With Corretto, we make our work on Open JDK available to our customers and the Open JDK community at large.

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.

About AWS

Diverse Experiences
AWS values diverse experiences. Even if you do not meet all of the preferred qualifications and skills listed in the job description, we encourage candidates to apply. If your career is just starting, hasn’t followed a traditional path, or includes alternative experiences, don’t let it stop you from applying.

Why AWS?
Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform. We pioneered cloud computing and never stopped innovating — that’s why customers from the most successful startups to Global 500 companies trust our robust suite of products and services to power their businesses.

Inclusive Team Culture
Here at AWS, it’s in our nature to learn and be curious. Our employee-led affinity groups foster a culture of inclusion that empower us to be proud of our differences. Ongoing events and learning experiences, including our Conversations on Race and Ethnicity (CORE) and Amaze Con (gender diversity) conferences, inspire us to never stop embracing our uniqueness.

Mentorship & Career Growth
We’re continuously raising our performance bar as we strive to become Earth’s Best Employer. That’s why you’ll find endless knowledge-sharing, mentorship and other career-advancing resources here to help you develop into a better-rounded professional.

Work/Life Balance
We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why we strive for flexibility as part of our working culture. When we feel supported in the workplace and at home, there’s nothing we can’t achieve in the cloud.

Key job responsibilities

• Design and develop sophisticated features in profiling tools and in the Java runtime
• Contribute to performance optimization and compliance with industry standard JVM specification
• Contributing to the design of future runtime features, and working with teams and services inside AWS to solve their business challenges
• Existing deployments of our product must be supported on an on-going basis, and the team will need to address any critical issues in live deployments

About the team
Amazon Corretto is Amazon’s distribution of Open JDK, used to run our thousands of Java services and also deployed by many AWS customers. The Corretto team is focused on improving Open JDK 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 Open JDK 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 Open JDK as a platform.

While Corretto is a relative newcomer to the scene, our team is composed of Open JDK Authors, Committers, and Reviewers, some with decades of experience in JDK, languages, compilers, and managed runtimes. We learn about where to invest in Open JDK 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.

Utility Computing (UC)

AWS Utility Computing (UC) provides product innovations — from foundational services such as Amazon’s Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS’s services and features apart in the industry. As a member of the UC organization, you’ll support the development and management of Compute, Database, Storage, Internet of Things (Iot), Platform, and Productivity Apps services in AWS, including support for customers who require specialized security solutions for their cloud services.
