Ideal candidates will have: 

• 5+ years of experience in malware analysis, threat intelligence, threat hunting or incident response.
• Deep understanding of the cybersecurity landscape, attack vectors and TTPs, especially on Windows.
• Experience in reverse engineering (x86/x64, ARM\ARM64) and malware analysis (statically and dynamically).
• Proficiency in C/C++ and scripting languages (Python, Powershell).
• Experience with creating signatures (YARA, Snort, Sigma) to identify and track malware families.
• Technical writing & content development skills.
