We are seeking a hands-on Senior Database Administrator with immediate production experience in PostgreSQL (Essential), MySQL, and MongoDB, alongside strong Terraform and DevOps practices. This is a delivery-critical role-ideal for a candidate who thrives in fast-paced environments and can own database infrastructure end-to-end, from provisioning to CI/CD integration.

• Collaborate with DevOps teams to integrate database operations into CI/CD pipelines.

DevOps & Automation:

• Compose Terraform configurations from infrastructure to Git pipelines.
• Work within CI/CD pipelines (GitLab or GitHub) to deploy and manage database changes.
• Ensure Git best practices for version control, collaboration, and pipeline setup.

Required Skills/Experience The ideal candidate will have the following:

• Proven production DBA experience in cloud-based environments.
• Hands-on expertise in PostgreSQL (Essential), MySQL, and MongoDB.
• Strong performance tuning and troubleshooting skills.
• Terraform proficiency is mandatory; ability to design, deploy, and manage database infrastructure using Infrastructure-as-Code (IaC).
• Experience working within CI/CD pipelines and DevOps practices.
• Familiarity with GitLab or GitHub and pipeline setup.

Desirable Skills/Experience Although not essential, the following skills are desired by the client:
