Key Job Responsibilities

The ideal candidate must demonstrate strong proficiency in malware reverse engineering, including the ability to analyze, disassemble, and deconstruct malicious software using industry-standard tools such as IDA Pro, Ghidra, and debuggers like x64dbg. Experience with static and dynamic analysis techniques is essential for identifying malware behavior, capabilities, and indicators of compromise.

A solid foundation in web application security is required, including expertise in identifying and mitigating vulnerabilities such as SQL injection, cross-site scripting (XSS), and authentication flaws. Familiarity with OWASP methodologies and tools like Burp Suite is expected.

Candidates must possess advanced threat hunting capabilities, leveraging hypothesis-driven approaches and behavioral analytics to proactively detect adversarial activity within enterprise environments. Proficiency in crafting custom detection rules and queries across SIEM platforms is essential.

A comprehensive understanding of network security is required, with a strong emphasis on DDoS mitigation and botnet research. The candidate must have experience analyzing botnet infrastructure, understanding command-and-control communication protocols, and identifying botnet propagation techniques. Proficiency in traffic analysis, volumetric attack pattern recognition, and DDoS defense strategies is essential. Hands-on experience with packet capture tools such as Wireshark, Zeek, and NetFlow analysis platforms is expected, along with the ability to research emerging botnet families and their evolving attack vectors.

A working knowledge of threat intelligence frameworks such as MITRE ATT&CK and familiarity with STIX/TAXII standards is preferred.
