About The Position

This role involves leading the migration of application and database servers to Oracle Cloud Infrastructure (OCI), designing and implementing OCI landing-zone architecture, and building and maintaining CI/CD pipelines. The engineer will implement Infrastructure as Code, partner with DBAs and application teams for database migrations, containerize workloads, establish core DevOps practices, implement monitoring and logging, and enforce security and compliance controls. The position also includes troubleshooting performance, producing documentation, and providing post-migration support and knowledge transfer.

Requirements

BA/BS degree and 4-6 years’ relevant experience OR equivalent combination of education and experience
Hands-on experience with Oracle Cloud Infrastructure (OCI) — compute, networking, storage, and IAM.
Strong DevOps toolchain experience: Terraform, CI/CD (GitHub Actions/Jenkins), Docker/Kubernetes.
Experience migrating Oracle Database and application servers to cloud environments.
Scripting proficiency (Python or Shell) and solid Linux systems administration.
Working knowledge of networking, security best practices, and cloud cost/performance optimization.

Nice To Haves

OCI certification (Architect or DevOps Professional) is a plus.

Responsibilities

Lead migration of application and database servers to Oracle Cloud Infrastructure (OCI), planning cutover sequencing to minimize downtime and ensure data integrity.
Design and implement OCI landing-zone architecture, including compute, storage, networking, and security (IAM, VCNs, security lists/NSGs), aligned to best practices.
Build and maintain CI/CD pipelines (e.g., GitHub Actions, Jenkins, OCI DevOps) for automated build, test, and deployment of application workloads.
Implement Infrastructure as Code (Terraform / OCI Resource Manager) for repeatable, version-controlled provisioning of environments.
Partner with DBAs and application teams to plan and execute Oracle Database migration strategies (Data Pump, RMAN, GoldenGate, or equivalent) with minimal disruption.
Containerize and orchestrate applicable workloads (Docker, Kubernetes/OKE) as part of the target-state architecture.
Establish core DevOps practices: source control workflows (Git/GitHub), branching strategy, automated testing gates, and release/change management.
Implement monitoring, logging, and alerting (OCI Monitoring/Logging, Grafana, or equivalent) to proactively detect and resolve issues.
Apply and enforce security and compliance controls throughout the migration lifecycle, including IAM policies, secrets management, and vulnerability remediation.
Troubleshoot and tune performance of migrated application and database servers post-cutover.
Produce migration runbooks, architecture diagrams, and standard operating procedures for the target environment.
Provide post-migration support, mentorship, and knowledge transfer to operations and support teams.
