• Design, develop, and maintain Infrastructure as Code using Terraform, AWS CDK, CloudFormation, or comparable frameworks.
• Build reusable IaC modules, templates, guardrails, and deployment patterns that improve repeatability, auditability, security, and engineering velocity.
• Automate provisioning, configuration, monitoring, auditing, patching, and deprovisioning of cloud infrastructure using tools such as Ansible, Chef, Puppet, Python, Bash/Shell, or PowerShell.
• Design, operate, and improve CI/CD pipelines using GitLab, GitLab Runners, GitHub Actions, or comparable DevOps platforms.
• Build pipeline workflows for automated build, test, security scanning, artifact management, deployment, validation, environment promotion, and rollback.
• Implement deployment practices such as blue/green deployments, canary releases, staged rollouts, automated rollback, branch strategies, approval gates, and artifact management.
• Support containerized workloads using Docker, Kubernetes, Amazon EKS, Amazon ECS, Helm, and related container ecosystem tools.
• Implement or support GitOps practices using tools such as ArgoCD or Flux where appropriate.
• Establish secure platform guardrails for identity management, secrets protection, encryption, logging, auditing, vulnerability management, change control, and least-privilege access.
• Design and operate AWS environments in alignment with applicable security and compliance requirements, including FedRAMP, FISMA, NIST-based controls, and customer-specific policies.
• Collaborate with cybersecurity teams, system owners, and auditors to support evidence collection, control mapping, remediation tracking, and continuous compliance.
• Build and maintain monitoring, logging, alerting, dashboards, runbooks, service health checks, and incident response procedures.
• Troubleshoot complex issues across AWS infrastructure, Linux systems, networking, CI/CD pipelines, containers, and application deployment workflows.
• Improve operational reliability through autoscaling, backup and recovery, disaster recovery planning, health checks, fault isolation, resilience engineering, and SLO/SLA support.
• Apply FinOps principles to improve cloud cost visibility, accountability, optimization, and operational efficiency.
• Implement tagging standards, cost allocation patterns, showback or chargeback readiness, rightsizing recommendations, scheduling, storage optimization, reserved capacity, savings plans, anomaly detection, dashboards, and recurring optimization reviews.
• Use approved Generative AI tools and automation agents to improve engineering productivity, reduce manual work, accelerate documentation, improve pipeline development, strengthen runbooks, and support incident response.
• Follow responsible AI practices, including sensitive-data handling, prompt hygiene, secret redaction, validation of AI-generated outputs, and human review of production-impacting changes.
• Mentor junior and mid-level engineers in AWS, DevOps, automation, cloud operations, security practices, FinOps, and engineering discipline.
• Create and maintain technical documentation, architecture diagrams, operating procedures, implementation plans, platform standards, and customer-facing technical recommendations.

Required Qualifications

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related technical field, or equivalent professional experience.
• 10+ years of progressive experience in cloud engineering, DevOps engineering, platform engineering, systems administration, infrastructure automation, enterprise architecture, or related technical roles.
• 5+ years of hands-on experience implementing DevOps practices, including CI/CD, automation, containerization, and infrastructure operations.
• Strong hands-on experience designing, deploying, securing, and operating production workloads in AWS.
• Experience with Infrastructure as Code using Terraform, AWS CDK, CloudFormation, or similar tools.

• Working knowledge of AWS security, networking, IAM, logging, monitoring, and cloud governance practices.
• Experience with container platforms such as Docker, Kubernetes, Amazon EKS, Amazon ECS, or Helm.
• Experience operating in regulated, compliance-driven, or security-sensitive environments.
• Experience with FedRAMP, FISMA, NIST-based controls, or comparable security frameworks.
• Experience applying FinOps practices to improve cloud cost visibility, accountability, and optimization.
• Demonstrated ability to troubleshoot complex technical issues across infrastructure, pipelines, networking, systems, and application deployment workflows.
• Demonstrated ability to mentor engineers and work effectively across architecture, security, development, infrastructure, operations, and customer teams.
