  • Security Integration into SDLC & CI/CD Pipelines: Collaborate with Development, Platform, and QA teams to integrate security best practices into the software development lifecycle (SDLC) and CI/CD pipelines. Ensure security is prioritised through automation tools, security testing, and vulnerability scanning as part of the continuous delivery process.
  • Security Assessments & Incident Response: Conduct security assessments, vulnerability scans and risk analyses to identify and address potential security weaknesses within cloud environments. Support the security operations team in incident response efforts related to cloud security incidents, ensuring timely detection, containment, and remediation.
  • Staying Current on Threat Intelligence & Industry Trends: Continuously research and stay up to date on emerging threats, vulnerabilities, and security trends within cloud infrastructure, container security, and DevSecOps practices. Regularly evaluate new security tools, frameworks, and technologies to enhance the organisation’s cloud security posture.
