We are seeking a Senior Database Administrator with strong expertise in PostgreSQL and MySQL to join our team. The ideal candidate is a hands-on professional capable of designing, deploying, maintaining, and optimizing highly available and scalable database systems. Experience with additional database technologies such as SQL Server and MongoDB is a strong advantage.

This role also involves working with cloud-native database services across providers such as AWS, Google Cloud, or Azure. Candidates with database migration experience will be given preference.

Key Responsibilities:

  • Design, configure, and maintain PostgreSQL and MySQL databases in production environments
  • Ensure high availability, disaster recovery, and performance optimization of database systems
  • Perform database migrations (on-premises to cloud and cross-cloud environments)
  • Troubleshoot and resolve database issues across development, testing, and production environments
  • Implement database monitoring, backup strategies, and security best practices
  • Collaborate with development, DevOps, and data teams on schema design, query tuning, and ETL pipelines
  • Participate in capacity planning, cost optimization, and automation initiatives
  • Document database systems, configurations, procedures, and runbooks


Requirements

Required Qualifications:

  • 3+ years of hands-on experience with PostgreSQL in production environments
  • 3+ years of experience with MySQL
  • Experience with at least one public cloud platform (AWS, GCP, or Azure), including managed database services (e.g., RDS, Cloud SQL)
  • Strong SQL skills with a solid understanding of indexing, query optimization, and partitioning
  • Proven knowledge of backup & recovery strategies, replication, and high-availability configurations
  • Proficiency in scripting and automation (e.g., Bash, Python, Ansible)
  • Experience supporting database migration projects (e.g., PostgreSQL to cloud, MongoDB to Atlas, SQL Server upgrades)

Advantageous Qualifications:

  • Familiarity with MongoDB, SQL Server, Neo4j, or other NoSQL databases
  • Experience with ETL tools, BigQuery, or data warehousing concepts
  • Relevant certifications (PostgreSQL, MySQL, AWS, GCP, or Azure)
  • Exposure to DevOps practices and infrastructure-as-code tools
