Application Security Perform security reviews, code audits, and threat modeling of web and mobile applications. Work with DevOps and development teams to integrate secure coding practices and tools (e.g., SAST, DAST, SCA). Conduct penetration testing and vulnerability assessments on internal and external applications. Remediate OWASP Top 10 and other emerging threats. Infrastructure & Server Security Harden Linux and Windows servers following CIS/NIST benchmarks. Implement endpoint security solutions (AV, EDR, MDM). Monitor, detect, and respond to system anomalies and unauthorized access. Manage patching and update cycles in coordination with system teams. Network Security Secure network architecture, firewall policies, VPNs, NAT, and VLAN segmentation. Analyze and mitigate threats like DDoS, MITM, spoofing, etc. Configure and manage intrusion detection/prevention systems (IDS/IPS). Perform routine audits and packet-level analysis for suspicious activity. Cloud Security Secure cloud infrastructure (Alibaba Cloud/AWS/Azure/GCP). Manage IAM, WAF, Security Groups, and cloud-native threat detection tools. Audit and improve security configurations in containers, CI/CD pipelines, and serverless deployments. Monitoring, Audit, and Compliance Work closely with compliance teams to meet standards like SAMA-CSF, ISO 27001, and PCI-DSS. Implement and tune SIEM/SOAR systems for proactive monitoring and incident response. Maintain audit trails, security reports, and logs for investigations and audits. Qualifications & Requirements Bachelors degree in computer science, Cybersecurity, or a related field. 4+ years of experience in cybersecurity roles with exposure to infrastructure and application security. Proficiency in tools like Burp Suite, Nessus, Wireshark, Nmap, Suricata, OSSEC/Wazuh, etc. Strong knowledge of TCP/IP, Linux security, cloud security, and secure coding principles. Experience with at least one cloud platform (Alibaba Cloud preferred). Familiarity with regulatory and compliance standards in the GCC region is a plus. Security certifications such as CEH, OSCP, CISSP, or CISM are a plus. Preferred Strong problem-solving and analytical skills. Ability to work under pressure in a fast-paced environment. Excellent communication skills to interface with technical and non-technical stakeholders. Self-motivated and able to work independently or as part of a team.
