Senior Software Development Engineer - Java Performance, Amazon Corretto at Amazon

Are you driven by performance? Are you able to identify bottlenecks and design approaches that solve them for a whole class of problems? Do you then find ways to make those problems disappear for the rest of the developer community? The Amazon JDK team, owner of Amazon Corretto, is looking for talented engineers skilled in high performance and high scale Java or similar systems (V8, Chakra, .NET...) to work on the future of Java at Amazon. We care about optimization for high scalability, availability, and efficiency, and also about going above and beyond to provide all Corretto and OpenJDK users with the best possible Java experience.
You will do well in this role if you are able to look clinically at a problem and identify possible root causes and solutions, up to and including authoring modifications or enhancements to the JVM/JDK themselves.

You Will

On this team you will be sharing your findings with the rest of the engineering community and contributing improvements back to OpenJDK where possible.

• Iterate, test new ideas, and shape the future vision for services and libraries built on Java.
• Work with development teams across Amazon as your direct customers. You will also interact with the community at large.
• Use your deep knowledge of the JDK to define how it’s used across the spectrum of products and services developed at Amazon.
• Contribute changes to the OpenJDK community and Corretto users.

Basic Qualifications

• Expert Java and JDK internals knowledge, including experience in managing and optimizing running services. Similar experience in other managed runtimes (e.g. .NET) is also ok.
• Bachelor’s Degree in Computer Science or related field or equivalent experience to a Bachelor's degree based on 3 years of work experience for every 1-year of education.
• 5+ years professional experience in software development
• Computer Science fundamentals in object-oriented design, data structures, and performance analysis.
• Proficiency in, at least, two modern programming languages such as C, C++, C#, Java, Python, or Ruby.

Preferred Qualifications

• Masters degree or higher in Computer Science or related field.
• Experience contributing to open source projects, preferably contributing to a runtime or widely used library.
• Experience taking a leading role in building complex software systems that have been successfully delivered to customers.
• Practice of modern software engineering, including coding standards, code reviews, source control management, build processes, testing, and releasing.
• Experience with distributed computing and enterprise-wide system operations.
• Experience in communicating with users, other technical teams, and senior management to collect requirements, describe software product features, technical designs, and product strategy.
• Experience mentoring junior software engineers and make them more effective.
• Experience influencing software engineers' best practices in your organization.
• Hands-on expertise in many disparate technologies, typically ranging from front-end user interfaces through to back-end systems and all points in between.
