Principal macOS Security Researcher

Reports to: Manager, Product Research
Location: Remote US

Compensation Range: $215,000.00 to $225,000.00 base plus bonus and equity

What You’ll Do:

• Lead product research initiatives that develop and evaluate macOS security product strategies and technologies
• Identify and prototype new telemetry from Apple's Endpoint Security API and other macOS subsystems to expand prevention, hardening, and detection capabilities
• Reproduce and analyze macOS attacks through hands-on execution of attacker techniques, malware detonation, and vulnerability exploitation
• Reverse engineer macOS malware and Apple's own security frameworks (XProtect, XProtect Remediator, Gatekeeper, TCC) to identify coverage gaps and inform product direction
• Prototype and test new tools and methodologies for offensive operations against macOS endpoints, including EDR evasion and bypass research
• Build proof-of-concept implementations that demonstrate the feasibility of new capabilities
• Document research findings and collaborate with Detection Engineering on writing and tuning detectors
• Coordinate with Product and Engineering teams to integrate and operationalize solutions developed by Security teams
• Stand up ephemeral research environments and attacker infrastructure using cloud, VM, and container technologies
• Track Apple platform changes across beta and release cycles, and assess their impact on agent capability, telemetry, and detection coverage
• Identify and address gaps in macOS product coverage, including false positive and false negative investigations
• Develop internal and external technical documentation to educate customers and adjacent teams on macOS security risks and opportunities
• Mentor and teach across the team on macOS internals, malware analysis, and research methodology
• Promote Huntress' reputation through public speaking, CFPs, blogs, and media interaction

What You Bring To The Team:

• Deep expertise in macOS system internals, including the security model, code signing and notarization, TCC, SIP, persistence, and the Mach-O file format
• Hands-on experience with Apple's Endpoint Security API and system extension development
• Authority on macOS security threats, attack techniques, and the current macOS malware landscape
• Familiarity with macOS fleet management (MDM, configuration profiles, mobileconfig deployment)
• Experience red teaming and performing attack emulation to bypass EDR on macOS
• Proficiency with Swift. Additional understanding of Go, Python, and/or Ruby is preferred.
• Experience with the MITRE ATT&CK matrix, Sigma, YARA, and Elasticsearch/Kibana
• Track record of building POCs and carrying research from concept through to a shipped product capability
• Experience leading data requirements work and tying it to cost/benefit analysis on collecting and storing only high-value telemetry
• Commitment to clear written documentation of research findings
• Comfortable reading Apple developer documentation, framework headers, and API references to answer undocumented questions
• An understanding of how SMBs utilize IT automation tools such as PSAs and RMMs is strongly preferred
• Bonus: Comfortable reverse engineering Mach-O binaries and scripted payloads using debuggers and a disassembler suite (Binary Ninja, IDA Pro, Hopper, or Ghidra)
