The AppleJDK team in Services is responsible for the Java runtime, and our mission is to make Java Services both fast and secure. The Java runtime is complex, with many subsystems: JIT compilers, language runtime, multiple garbage collectors, and FFM interface for native apps. The interactions with native code must do so in a memory safe way. In this role, you will work across all areas of the runtime, focusing on improving security and stability. You will drive innovations in the Java Runtime and tools. You will also ensure the application of current best practices in the Java runtime, and work with Services at Apple scale.
In this role, you have the opportunity to help secure the Java virtual machine. The AppleJDK team at Apple is looking for system programmers with experience in programming languages, compilers, and virtual machines. You will be working to deliver secure services for all Apple Java services both proactively, by ensuring new features are implemented securely, and reactively, by responding to and addressing Java security work across Services. This is a high-impact, high-autonomy role at the intersection of systems programming, language runtimes, and performance engineering. Join us!
