2. Linux Systems Management (Red Hat / Ubuntu)

- Administer, secure, patch, and troubleshoot Linux environments, ideally Red Hat and

Ubuntu.
- Automate recurring system administration and maintenance tasks through scripting.

3. Production Support & Operational Ownership

network, application, and cloud layers.
- Own incidents through recovery, validation, and follow-up; lead root cause analysis and preventive improvements.

4. Platform, Network & Maintenance Operations

- Set up, configure, and manage platform networks; resolve connectivity issues.
- Plan and execute patching and troubleshooting within customer maintenance windows;

coordinate dependencies, recovery steps, health checks, and follow-up.

5. AWS Cloud Infrastructure

- Manage infrastructure changes using Terraform or CloudFormation.

6. Stakeholder Communication

- Coordinate maintenance scope, timing, and availability with internal teams and customer stakeholders.
- Provide incident and maintenance updates; document changes, validation, resolutions,

and handoffs, and participate in operational reviews.

7. GitHub & CI/CD (Supporting Responsibilities)

- Support GitHub repositories, branching, reviews, pull requests, branch protection, and releases.
- Build and maintain GitHub Actions for builds, tests, scanning, and deployment; apply secrets management, SAST, DAST, and dependency scanning to improve pipeline security,

reliability, and speed.

- 4+ years in DevOps, Platform Engineering, or SRE, supporting complex production cloud platforms.
- MySQL DBA expertise: replication, backups, recovery, performance diagnosis, and tuning.
- Linux administration: security, patching, troubleshooting, and scripting; Red Hat and

What We’re Looking For

- A hands-on problem solver who takes ownership, follows through, communicates clearly,

and improves service reliability.

- Maintenance completed within agreed windows, with validation, clear updates, and documented follow-up.
- Faster recovery, fewer recurring incidents, and stakeholder confidence; secure, efficient pipelines as a supporting outcome.
