Lead Cloud Security Engineer

We're looking for a highly skilled and hands-on Lead Cloud Security Engineer to help secure our cloud environments, with a strong focus on AWS as our primary cloud provider.

• Conduct risk assessments, threat modelling, and vulnerability analysis across cloud platforms.

• Design and deploy automated security workflows and remediation processes.
• Collaborate with DevOps and engineering teams to embed security into CI/CD pipelines.
• Respond to and manage cloud-related security incidents.
• Develop and enforce cloud security policies, standards, and controls.
• Provide expert guidance and support to teams on cloud security principles and practices.

What makes you a great fit?

• Degree in Cybersecurity, Computer Science, Information Technology, or a related field.
• Cloud security certifications (AWS, Azure, or GCP); AWS Security Certification preferred.
• Strong hands-on experience with AWS; familiarity with Azure and GCP is a plus.
• Experience with infrastructure-as-code tools such as Terraform, CloudFormation, or Ansible.
• Proven experience securing CI/CD pipelines using tools like Jenkins, Bamboo, or similar.
• Proficiency in scripting languages such as Python, PowerShell, or Bash.
• Familiarity with container technologies including Docker and Kubernetes.
• Solid understanding of common application security threats (e.g., SQL injection, XSS).
• Experience with Prisma Cloud CNAPP would be highly beneficial.
• Strong communication and stakeholder engagement skills.
