Requirements

Key Responsibilities:

Cybersecurity Operations:

  • Lead investigation and resolution of complex security incidents and breaches, coordinating with L1 and L2 teams as necessary.
  • Monitor security tools and platforms (SIEM, EDR, IDS/IPS) to detect threats and mitigate vulnerabilities.
  • Perform root-cause analysis for incidents, implementing preventative measures and documenting lessons learned.
  • Conduct penetration tests and vulnerability assessments, ensuring remediation plans are implemented effectively.
  • Develop and enforce security policies, procedures, and guidelines to protect sensitive data and systems.

Cloud/Infrastructure Security:

  • Design and implement robust security controls for cloud platforms (AWS, Azure, GCP) and hybrid environments.
  • Manage identity and access management (IAM), ensuring least privilege principles are applied across the infrastructure.
  • Conduct regular audits and assessments to validate compliance with security standards and regulations (e.g., GDPR, ISO 27001).
  • Protect virtualized environments and containers using tools like Kubernetes security, Docker, or Azure Kubernetes Service (AKS).
  • Monitor cloud environments for misconfigurations, unauthorized changes, or suspicious activity using tools like Prisma Cloud, Microsoft Defender for Cloud, or AWS Security Hub.

Threat Intelligence and Response:

  • Stay updated on the latest cybersecurity trends, threats, and vulnerabilities to ensure proactive protection measures.
  • Collaborate with Threat Intelligence teams to analyze emerging risks and recommend appropriate countermeasures.
  • Develop and execute incident response playbooks for cloud and infrastructure-specific scenarios.

Security Automation and Optimization:

  • Implement automation solutions to improve detection, response, and remediation times using tools like SOAR platforms (e.g., Splunk Phantom, Palo Alto Cortex XSOAR).
  • Optimize security tool performance and conduct regular health checks to ensure systems are running efficiently.
  • Drive continuous improvement in operational processes by identifying inefficiencies and proposing enhancements.

Collaboration and Reporting:

  • Partner with DevOps, CloudOps, and IT teams to ensure seamless integration of security measures into infrastructure workflows.
  • Provide regular security reports and metrics to leadership, highlighting trends, risks, and mitigations.
  • Mentor and train junior analysts in advanced security operations and best practices.

  • Strong expertise in Cybersecurity domains: threat hunting, incident response, vulnerability management, and penetration testing.
  • Advanced knowledge of cloud security tools and frameworks for AWS, Azure, and GCP.
  • Proficiency with security tools: SIEM (Splunk, QRadar, Sentinel), EDR (CrowdStrike, Carbon Black), IDS/IPS (Snort, Suricata).
  • Experience with encryption technologies, firewalls, VPNs, and Zero Trust architectures.
  • Proficiency in scripting or programming (Python, Bash, PowerShell) for security automation.

Experience:

  • 5+ years in cybersecurity or IT security roles, with at least 2 years in cloud/infrastructure security.
  • Proven experience in handling L3 escalations for complex security incidents.
  • Familiarity with regulatory compliance standards (e.g., NIST, GDPR, PCI DSS, ISO 27001).

Soft Skills:

  • Strong analytical and critical thinking skills to resolve complex security challenges.
  • Excellent communication skills for cross-functional collaboration and incident reporting.
