Provide technical leadership and mentorship, promoting best practices in automation, cloud, and security.
Enhance operational security with advanced monitoring, logging, and alerting solutions.
Participate in Agile SAFe ceremonies and contribute expertise on security and automation practices.
Apply networking and network security principles (VPC, subnets, VPNs, NACLs, Security Groups) to cloud architectures.
Troubleshoot and resolve issues related to CI/CD pipelines, security tools, and operational processes.
Train and guide teams in CI/CD, DevSecOps, and operational security methodologies.
Ensure compliance with industry standards and regulatory frameworks through automated checks.
Develop and maintain documentation for CI/CD workflows, operational procedures, and security protocols. Qualifications (Required Skills/Experience): 3+ years of experience in DevOps roles.
3+ years of experience scripting with languages such as Python, MATLAB, or similar.

3+ years of experience implementing CI/CD practices with GitLab, Azure DevOps, or comparable tools.
3+ years of experience working within Agile development teams.
1+ years of experience integrating security tools into CI/CD pipelines.
Hands-on experience with cloud platforms (AWS, Azure), infrastructure as code (Terraform), and automation tools (Puppet, Ansible, Chef). Preferred Qualifications (Desired Skills/Experience): Bachelor’s degree or higher.
Professional certifications such as AWS Certified DevOps Engineer, CISSP, or Docker Certified Associate.
Experience with containerization and orchestration technologies (Kubernetes, Docker, OpenShift, Tanzu).
Familiarity with security frameworks such as NIST 800-53.
Experience with network security and intrusion detection/prevention systems.
Exposure to serverless architectures and associated security considerations.
