- Develop, refine, and maintain SIEM rules, alerts, dashboards, and playbooks for proactive threat detection.

- Automate repetitive SecOps processes (e.g., enrichment, remediation, alert triage) to improve efficiency and reduce noise.
- Conduct threat hunting activities to identify hidden threats and vulnerabilities.
- Collaborate with devops and engineering teams to embed security best practices into systems and workflows.
- Perform log analysis and security monitoring across cloud, endpoint, and network environments.
- Lead security assessments and participate in vulnerability management and remediation programs.
- Partner with compliance and risk management teams to support audits and regulatory requirements.
What you'll bring
- 5+ years of hands-on experience in Security Operations
- Strong knowledge of SIEM platforms
- Expertise in threat detection, malware analysis, and forensic investigation.
- Proficiency with scripting and automation tools (Python, Bash, etc.).
- Solid understanding of network protocols, firewalls, IDS/IPS, EDR, and cloud security controls.
- Experience with cloud platforms (AWS and GCP) and their native security services.
- Familiarity with MITRE ATT&CK, NIST, ISO, and other security frameworks.
- Excellent communication and leadership skills, with experience guiding teams or projects.
- Security certifications a plus
