🎯 Role Definition

A Security Researcher is a highly specialized cybersecurity professional who acts as a digital detective and an ethical hacker. In this pivotal role, you are at the forefront of cyber defense, proactively identifying and neutralizing threats before they can be exploited by malicious actors. This involves a deep, persistent curiosity to dissect complex systems, from software and hardware to cloud environments and network protocols. You'll spend your time reverse-engineering malware, discovering zero-day vulnerabilities, and understanding the tactics of global threat actors. The ultimate goal is to generate unique, actionable intelligence and research that strengthens an organization's security posture and contributes to the safety of the broader digital ecosystem.

Core Responsibilities

Primary Functions

  • Proactively identify, analyze, and research new and emerging security vulnerabilities, zero-day exploits, and advanced attack techniques across a wide range of software, hardware, and network protocols.
  • Conduct in-depth reverse engineering of malware, exploits, and suspicious binaries to understand their functionality, attack vectors, and indicators of compromise (IOCs).
  • Perform comprehensive vulnerability assessments and penetration testing on complex systems, including web applications, mobile platforms, cloud infrastructure (AWS, Azure, GCP), and embedded devices (IoT).
  • Develop and maintain custom tools, scripts, and frameworks to automate security research, vulnerability discovery, and exploit development processes.
  • Author detailed, high-quality technical reports, whitepapers, and blog posts that clearly document research findings, vulnerability details, and recommended mitigation strategies for both technical and executive audiences.
  • Collaborate closely with engineering and product development teams to provide expert security guidance, validate fixes for identified vulnerabilities, and integrate security best practices into the software development lifecycle (SDLC).
  • Monitor the global threat landscape, tracking threat actor groups, their tactics, techniques, and procedures (TTPs), and evolving malware campaigns to produce actionable threat intelligence.
  • Develop robust proof-of-concept (PoC) exploits for discovered vulnerabilities to demonstrate their potential impact and assist in the prioritization of remediation efforts.
  • Participate in the responsible disclosure process by coordinating with software vendors and open-source projects to report vulnerabilities and ensure timely patching.
  • Analyze large-scale datasets, including network traffic, system logs, and threat intelligence feeds, to uncover patterns of malicious activity and identify previously unknown threats.
  • Contribute to the creation and refinement of detection signatures, rules, and heuristics for security products like Intrusion Detection/Prevention Systems (IDS/IPS), Web Application Firewalls (WAF), and Endpoint Detection and Response (EDR) solutions.
  • Present cutting-edge security research findings at major industry conferences (e.g., Black Hat, DEF CON, RSA) and local security meetups to contribute to the broader security community.
  • Conduct both static and dynamic code analysis (SAST/DAST) on a variety of programming languages and platforms to discover security flaws at the source code level.
  • Investigate and perform root cause analysis on high-impact security incidents and breaches to understand the attack lifecycle and inform future defensive strategies.
  • Develop and deliver technical training and mentorship to junior researchers, security analysts, and other members of the technical staff.
  • Engage in capture-the-flag (CTF) competitions, bug bounty programs, and other security challenges to continuously sharpen technical skills and stay current with offensive security methodologies.
  • Research and evaluate the security implications of new and emerging technologies, such as blockchain, artificial intelligence/machine learning (AI/ML), and quantum computing.
  • Perform protocol analysis and fuzzing on network services and file formats to uncover memory corruption bugs and other exploitable vulnerabilities.
  • Maintain a deep, expert-level understanding of operating system internals (Windows, Linux, macOS) and their associated security mechanisms and weaknesses.
  • Reverse engineer mobile applications (iOS/Android) to identify vulnerabilities in the app's code, data storage, and communication protocols.

Secondary Functions

  • Mentor junior researchers and analysts, providing technical guidance and active knowledge sharing.
  • Contribute to the development and maintenance of the research lab environment, infrastructure, and toolsets.
  • Liaise with external threat intelligence partners and information sharing communities (ISACs) to exchange data and insights.
  • Participate in internal security awareness and training initiatives by presenting research findings and threat landscape updates to the wider organization.

Required Skills & Competencies

Hard Skills (Technical)

  • Reverse Engineering: High proficiency with tools like IDA Pro, Ghidra, Binary Ninja, and debuggers (x64dbg, WinDbg, GDB).
  • Operating System Internals: Deep knowledge of Windows, Linux, and/or macOS internals, including memory management, process scheduling, and kernel architecture.
  • Networking: Expert understanding of TCP/IP, as well as common application and encryption protocols (HTTP, DNS, SSL/TLS).
  • Scripting & Automation: Advanced proficiency in at least one scripting language (e.g., Python, Ruby, PowerShell) for tool development and task automation.
  • Low-Level Programming: Strong familiarity with C/C++ and Assembly (x86/x64, ARM).
  • Vulnerability Analysis: Experience with modern fuzzing techniques (e.g., AFL++), static analysis (SAST), and dynamic analysis (DAST) tools.
  • Penetration Testing Tools: Hands-on experience with frameworks and tools like Metasploit, Burp Suite, and Nmap.
  • Exploit Development: Knowledge of common vulnerability classes (OWASP Top 10, CWE Top 25) and exploit mitigation technologies (ASLR, DEP, CFG).
  • Malware Analysis: Experience dissecting and classifying various malware types, including ransomware, trojans, and rootkits.
  • Cryptography: A solid understanding of cryptographic principles, common algorithms, and their practical weaknesses.

Soft Skills
