  • Conduct threat modeling for both applications and infrastructure to identify and mitigate risks early in the lifecycle.
  • Secure cloud platforms, including identity controls, configuration hardening, and policy enforcement.
  • Assess and secure financial web applications hosted in AWS through code reviews, penetration testing coordination, and architecture reviews.
• Security Platform Operations
  • Operate and monitor key security platforms such as:
  • EDR/XDR solutions
  • DLP solutions across endpoints, cloud, and email
  • Email Security Solutions
  • Ensure proper tuning, coverage, and integration of security tools with enterprise IT systems and logging pipelines.
• Security Monitoring & Response
  • Participate in day-to-day security monitoring using SIEM, EDR/XDR, and other detection platforms to augment the SOC team when required.
  • Assist in configuring and tuning monitoring tools for optimal detection coverage.
  • Collaborate with different teams to investigate security alerts and incidents.
  • Support incident response activities, including triage, containment, and remediation efforts.
  • Contribute to post-incident reviews and continuous improvement of detection and response processes.
• Threat & Vulnerability Management
  • Implement and coordinate the identification, triage, and remediation of vulnerabilities across cloud, endpoints, and infrastructure.
  • Support ongoing patch management strategy, vulnerability scanning, and threat intelligence correlation.
• Endpoint & Infrastructure Hardening

  • Align baseline configurations with CIS benchmarks and industry best practices.
• Detection Engineering
  • Understand, implement, and tune detection rules and logic in SIEM/XDR platforms for proactive threat identification.
  • Collaborate with different colleagues to improve alert fidelity, reduce false positives, and create meaningful security detections。
• Business Continuity & Risk
  • Contribute to BCP/DR planning and implementation with a security-first approach.
  • Collaborate with stakeholders to ensure critical business processes remain secure and resilient.

• 5+ years of progressive experience in information security roles, preferably with exposure across application, cloud, and infrastructure domains.
• Bachelor’s Degree in Computer Science, Information Technology, Software Engineering, Computer Engineering, Electronics Engineering, or related field.
• Experience in managing and securing cloud platforms.
• Hands-on experience with security tools including EDR, DLP, email security, vulnerability scanners, and SIEM.
• Working knowledge of secure SDLC practices, application security testing, and DevSecOps integration.
• Experience with identity and access management (IAM), conditional access, and zero trust architecture.
• Intermediate background in detection engineering, incident response, and threat modeling methodologies (STRIDE, MITRE ATT&CK, etc.).
• Familiarity with regulatory and compliance standards (e.g., NIST, ISO 27001, GDPR, SOC 2, PCI-DSS).
• Excellent communication and collaboration skills; ability to work across technical and non-technical teams.
