Description

The JavaScriptCore team in WebKit is responsible for the JavaScriptCore engine, and our mission is to make JavaScript and WebAssembly execution both fast and secure. JavaScriptCore is complex, with many subsystems: the compilation pipeline, the language runtime, the garbage collector and memory allocators, and the API for native apps. These subsystems run untrusted, third-party code, and all of them must do so in a memory safe way.

In this role, you will work across all areas of the engine, focusing on improving security and stability. You will drive new innovations in the security architecture of the codebase. You will fix security issues and respond to fuzzing. You will also ensure that security processes in JavaScriptCore are updated to current best practices and set the project up for a secure future.

Minimum Qualifications

  • BS in computer science or equivalent

  • Experience programming in modern C++ Excellent debugging, critical thinking, and communication skills

  • Experience developing privacy and security-sensitive software

  • Experience with compilers, parsers, and interpreters

  • Experience with assembly-level programming

Preferred Qualifications

  • Hands-on experience with VMs with just-in-time compilers (e.g. JavaScript engines and JVMs)

  • Experience with web browsers

  • Experience with memory allocators and garbage collectors

  • Experience with fuzzing, security architecture, and memory safety
