• Develop reusable modules, playbooks, and automation libraries that standardize infrastructure deployment patterns.
• Engineer and enhance platform services, including CI/CD pipelines, secrets management, artifact repositories, and configuration management systems.
• Implement automated testing, validation, and security scanning for IaC and platform components.
• Build and maintain self service automation workflows, enabling application and infrastructure teams to consume services through APIs, catalogs, or pipelines.
• Integrate automation with cloud platforms, virtualization systems, network/security appliances, and enterprise tooling.
• Implement drift detection, compliance checks, and automated remediation workflows.
• Collaborate with cloud, network, security, and SRE teams to define automation standards and best practices.
• Troubleshoot complex infrastructure, automation, and CI/CD issues across hybrid environments.
• Contribute to documentation, architectural diagrams, and engineering design reviews.

Required Qualifications

• 5–8+ years of experience in DevOps, platform engineering, cloud engineering, or infrastructure automation roles.
• Strong hands on experience with Terraform or Ansible (preferably both).
