Malware Research Engineer - Mac

About the role

We're looking for a Mac Malware Researcher who will own end-to-end analysis of sophisticated macOS threats—from reverse engineering Mach-O binaries to developing detection strategies that ship directly into our security products. You'll sit at the intersection of threat research and engineering, collaborating closely with detection and product teams to harden coverage for 25 million+ users.

What you'll do

• Reverse engineer Mach-O binaries, malicious installers (PKG, DMG), and scripts to identify spyware, backdoors, loaders, and adware behaviors
• Develop and maintain detection signatures, behavioral rules, YARA rules, and generic/heuristic signatures to deliver rapid, scalable protection
• Research macOS-specific persistence mechanisms—LaunchAgents, LaunchDaemons, cron jobs, login items—and study evasion techniques including notarization abuse
• Conduct advanced static and dynamic analysis, memory forensics, and behavioral analysis to track malware families, variants
• Write technical reports and threat intelligence documentation, and advocate for research findings through internal stakeholder briefings, external blogs, whitepapers

• 3–5 years in software engineering
• Research
• Python
• C++
• Shell scripting
