Ability to locate, analyze, and interpret forensic artifacts in Windows and Linux during investigations (e.g., registry, event logs, browser history, memory dumps) using tools like Volatility and FTK.
• Application Security Knowledge: Familiarity with application-level attacks, prevention methods, hardening configurations, and log analysis for applications like web applications and databases. Proficiency in scripting languages (e.g., Bash, Python, PowerShell) for automation and process improvement. Strong understanding of malware behavior, persistence mechanisms, and the ability to perform static and dynamic analysis, including sandbox report interpretation and reverse engineering.
• Purple Teaming: Knowledge of various cyber attacks, simulations, and identification methods. Ability to lead purple teaming activities, developing scenarios and engaging in both blue and red team activities. Proficiency with offensive tools like Metasploit, Nmap, Cobalt Strike, Hydra, John the Ripper, Burp Suite, Mimikatz, Bloodhound, and others.
• Threat Hunting: Experience with advanced persistent threat (APT) tactics, techniques, and procedures (TTPs) mapped to the cyber kill chain. Create hypotheses for proactive threat hunts and utilize tools like MISP and Jupyter Notebook for effective hunts.
• Process Development: Develop playbooks and templates for incident management. Identify and address gaps in current processes, collaborate with other teams, and build streamlined cross-departmental processes.
• Automation Development: Identify repetitive tasks and develop automation ideas. Collaborate with automation teams to build capabilities using platforms like CrowdStrike Fusion, AWS Lambda, Azure Logic Apps, XSOAR, and Python scripts.
• Languages: Query Languages: Proficiency in query languages like KQL and Logscale for investigations and log analysis. Scripting Languages: Proven experience in scripting.
• Managing Relationships: Develop and maintain key relationships with forensics, security operations governance, cyber defence engineering, risk and compliance, IT, and other business units.

Soft Skills:

• Operations Management & Issue Resolution: Ensure smooth operations and continuity by proactively identifying and addressing operational issues, team dynamics, and inefficiencies in ticket handling.
• Report Writing: Ability to write reports that convey highly technical information whilst remaining accessible to a non-technical audience (including at executive level).
• Communication: Exhibit excellent written/verbal communication skills, with the ability to develop documentation and explain technical details in a concise manner.
• Mentorship: training and guiding junior team members, promoting a culture of knowledge sharing and continuous learning.
• Critical Thinking, Adaptability & Problem-Solving: Demonstrate strong analytical skills and flexibility to adapt to changing priorities and emerging cybersecurity threats while effectively solving problems.
• Time Management & Organization: Prioritize tasks efficiently and maintain organized documentation and processes to enhance team productivity.
• Teamwork & Positive Attitude: Foster a collaborative environment where team members feel supported, practicing active listening, motivating the team, and maintaining a positive demeanor, especially in high-pressure situations.

Qualifications:

• 7+ years of experience in cybersecurity, with a minimum of 3 years in a SOC or incident response leadership role.
• Relevant advanced certifications (e.g., GCIA, GSEC, CEH, GCDA, GCIH, GCFA, OSCP) are highly desirable but not essential.
• Proven self-learning abilities demonstrated through research, GitHub projects, bug hunting, active participation in public cybersecurity forums, or high scores on platforms like HTB, Immersive Labs, TryHackMe, and SANS CTF.

Bonus Points:

• Knowledge of reverse engineering tools (disassemblers, decompilers, debuggers) and processes (unpacking malware, reconstructing code logic, etc).
• Low-level programming experience for example, C, Python, Go, and/or other languages desirable.
• Assembly language knowledge is a plus.
• Experience in User-Interface/User-Experience (UI/UX) design and development.
• Development and deployment of dockerized applications.
• 3 years of experience in static and dynamic malicious code reverse engineering.
• Experience with multiple platforms (Linux, MacOS, mobile, etc.) is a plus.
• A background in intelligence is a plus.
