The engineer will be responsible for embedding security into every stage of the software development lifecycle while ensuring high availability and resilience of deployed systems.
Responsibilities:

• Develop, maintain, and secure CI/CD pipelines to support application and infrastructure delivery.
• Integrate automated testing, vulnerability scanning, and compliance validation into build and deployment workflows.
• Architect and manage containerized environments using Kubernetes and Docker.
• Define and enforce Infrastructure as Code (IaC) standards with tools such as Terraform, Ansible, or CloudFormation.
• Oversee cloud security posture management across AWS, Azure, or Google Cloud Platform, ensuring governance and compliance requirements are met.
• Build and manage monitoring, logging, and alerting solutions to ensure system reliability, scalability, and security.
• Perform risk assessments, threat modeling, and security audits for infrastructure and applications.
• Troubleshoot complex deployment, configuration, and environment issues across multiple platforms.
• Provide mentoring and technical leadership to developers, operations engineers, and junior staff.
• Document processes, system architectures, and security practices to support long-term sustainability.

Required Skills and Experience:

• 5 7+ years of professional experience in DevSecOps, Site Reliability Engineering, or Infrastructure/Cloud Security.
• Strong expertise in CI/CD automation tools (Jenkins, GitLab CI/CD, GitHub Actions, or equivalent).
• Proficiency with containers (Docker) and orchestration platforms (Kubernetes, OpenShift).
• Hands-on experience with Infrastructure as Code (Terraform, Ansible, CloudFormation, Puppet, or Chef).
• Deep knowledge of secure coding practices, threat modeling, and vulnerability management.
• Cloud platform expertise (AWS, Azure, or Google Cloud Platform), including IAM, VPC design, and secure deployment automation.
• Proficiency in scripting languages such as Python, Bash, or PowerShell.
• Experience with secrets management (Vault, AWS KMS, Azure Key Vault, or similar).
• Ability to integrate security tools into DevOps pipelines (SAST, DAST, dependency scanning, container image security).
• Solid understanding of networking concepts, TLS/SSL, VPNs, firewalls, and zero-trust security models.
