Ready to join a mission that matters? The future of cybersecurity starts with you. About the Role: In this role you will research and develop techniques for detecting malicious activity occurring on macOS systems. Once researched you will develop them into production level solutions for deployment in the endpoint sensor. The role is a split of research and implementation working alongside a small and nimble group of MacOS engineers and often leveraging shared code with other sensor platforms such as Windows and Linux. Successful engineers in this role have: an understanding of macOS kernel and user space, a passion for continuous learning to keep up with an ever-changing threat landscape, a creative mindset for designing new detection methods and the discipline to write fast and reliable code. This role is hybrid, requiring 2-3 days per week on-site at one of the posted locations
