Security Engineer

*Mission* 

This role is responsible for the proactive engineering and technical optimization of the organisation security detection stack. You will take ownership of triaging and investigating security events from GuardDuty, Sysdig, and WAF telemetry, moving beyond dashboard monitoring to perform active troubleshooting via log analysis and direct cluster interaction (with kubectl ang gcloud). You will be expected to proactively tune detection logic to reduce false positives and develop automation scripts in Python or Bash to eliminate manual operational tasks. Additionally, you will drive the remediation of GitHub Advanced Security findings by providing developers with actionable code-level fixes and ensuring security configurations are managed as code.

*What We Look For in You*

• 3+ years of professional experience in application / cloud security
• Ability to analyze WAF traffic and cloud telemetry (e.g., GuardDuty, Sysdig) to identify attack patterns, eliminate false-positives and tune the tooling.
• Hands-on experience applying and auditing/remediating security best practices in AWS/GCP, Kubernetes and containerized infrastructure
• Strong understanding of application and API security principles (e.g., OWASP Top 10, OWASP API Top 10).
• Practical experience with source code analysis and the ability to read and understand Python and/or Java.
• Hands-on experience with security monitoring tools including SAST, DAST, and SCA + practical experience integrating them within the CI/CD pipelines.
• Solid understanding of data security, encryption techniques, and secure data handling.
• Working knowledge of network protocols (TCP/IP, DNS) and security concepts (WAFs, IDS).
