Efficiently gain familiarity with the design and implementation of existing codebases and contribute to security hardening projects for core OS components (e.g., memory safety adoption, mitigation deployment, sandboxing/isolation, refactoring).
Update existing software or create new codebases to achieve security goals; implement projects using appropriate languages (Swift, Objective-C, or C++).
Adopt or update unit tests and collaborate with QA engineers on functional testing.
Document changes and new architectural elements; create training materials required for partner teams to maintain changes going forward.
Communicate collaboratively and effectively across all project phases with cross-functional teams.
