Position Summary

We are seeking a highly skilled and proactive Senior Cyber Security Engineer to join our core MDR delivery team. In this pivotal role, you will be responsible for defending our clients by actively hunting for threats, leading investigations into sophisticated security incidents, and continuously enhancing our detection and response capabilities. You will go beyond traditional monitoring to perform deep forensic analysis, develop custom detection logic, and guide containment and eradication efforts for a diverse portfolio of clients. This is a hands-on role for a practitioner who thrives in a dynamic, client-focused Security Operations Center (SOC) environment.

Key Responsibilities

• Threat Hunting & Detection Engineering:
  • Conduct proactive, hypothesis-driven threat hunting across client environments to identify advanced and persistent threats.
  • Develop, refine, and deploy custom detection rules (SIEM queries, YARA, EDR logic) to enhance detection accuracy and coverage.
  • Analyze adversary TTPs (Tactics, Techniques, and Procedures) to evolve hunting methodologies and detection strategies.
• Incident Response & Investigation:
  • Serve as the primary escalation point and lead investigator for complex security incidents.
  • Perform in-depth forensic analysis (endpoint, memory, network, cloud) to determine scope, root cause, and impact.
  • Lead remote containment, eradication, and recovery efforts in close coordination with client IT teams.
• MDR Service Delivery & Client Partnership:
  • Act as a trusted technical advisor for assigned MDR clients, providing expert insights during security reviews and post-incident briefings.
  • Author and deliver detailed incident reports, executive summaries, and actionable remediation guidance.
  • Proactively recommend security improvements based on observed telemetry, threats, and client risk profiles.
• Security Stack Mastery & Optimization:
  • Demonstrate deep expertise in our MDR technology stack (EDR/XDR, SIEM, network detection, threat intelligence platforms).
  • Optimize tool configurations, integrations, and alert workflows to maximize detection efficacy and operational efficiency.
• Knowledge & Process Development:
  • Contribute to the continuous improvement of MDR playbooks, runbooks, and standard operating procedures.
  • Mentor and provide technical guidance to junior Security Analysts and Engineers.
  • Develop and share threat intelligence briefings tailored to client industries.

Qualifications

Required:

• Bachelors degree in Cybersecurity, Computer Science, or a related field, or equivalent hands-on experience.
• Minimum of 5 years in hands-on security operations, with at least 2 years focused on threat hunting, incident response, or within an MDR/MSSP environment.
• Deep technical experience with:
  • EDR platforms (e.g., CrowdStrike, Microsoft Defender for Endpoint, SentinelOne).
  • SIEM solutions (e.g., Splunk, Microsoft Sentinel, Elastic) for advanced querying and investigation.
  • Digital forensics and incident response (DFIR) methodologies and tools.
• Proven ability to analyze malware, interpret attacker behavior, and conduct investigations across the cyber kill chain.
• Strong knowledge of network protocols, OS internals (Windows, Linux, macOS), and cloud (AWS, Azure, GCP) security monitoring.
• Excellent communication skills, with the ability to convey technical details clearly to both technical and executive audiences.

Preferred:

• Industry certifications such as GCFA, GNFA, GCIH, OSCP, CySA+, or platform-specific credentials (Splunk, CrowdStrike).
• Experience in a consulting or client-facing MDR role.
• Scripting proficiency (Python, PowerShell) for automation and tool creation.
