- Implement security best practices:
- Authentication & authorisation (RBAC)
- TLS / encryption at rest
- Auditing and access controls

- Automate MongoDB operations using Ansible, scripts, and CI/CD pipelines
- Support MongoDB deployments on AWS / Azure / GCP
- Work closely with application and DevOps teams on schema design and performance optimisation
- Participate in on-call rotations and handle production incidents
- Maintain operational documentation and runbooks
