• Strong knowledge of SIEM, SOAR, EDR, and log analytics tools (e.g., Splunk, Elastic, Sentinel, Cortex XSOAR)
• Proven experience (3+ years) in Security Operations, Security Engineering, or related roles in high-tech or finance environments
• Hands-on experience with automation/scripting languages (e.g., Python, PowerShell, Bash) and infrastructure-as-code tools
• Familiarity with AI/ML applications in cybersecurity (e.g., anomaly detection, behavior analytics) is highly desirable
• Deep understanding of threat intelligence frameworks and attack techniques (e.g., MITRE ATT&CK, threat modeling)
• Experience working with cloud environments (e.g., AWS, Azure) and containerized workloads (e.g., Kubernetes, Docker) from a security perspective
• Strong analytical and communication skills, with a mindset for continuous improvement and innovation
• Relevant certifications are a plus (e.g., GCIA, GCTI, GSEC, OSCP, or equivalent)
