• Integrate security protocols into the DevOps lifecycle, ensuring adaptability against vulnerabilities.
• Partner with software engineers, QA, and other teams to ensure efficient deployment, monitoring, and maintenance of applications.
• Keep up to date with the latest industry trends, tools, and guidelines in DevOps and cloud infrastructure.

What you'll bring:

• Computer science, software engineering, or relevant technical background required.
• 5 + years of professional experience in DevOps and infrastructure management.
• 5+ years of specific experience with Cloud platforms (AWS/Azure/GCP)
• Proficient in Kubernetes, Docker, and Terraform.
• Experience with the Azure cloud platform, handling workloads, provisioning & deployments.
• Deep knowledge of security standards in cloud and DevOps contexts.
