The successful candidate will have a strong foundation in both traditional and emerging database technologies, with hands-on experience in automation, performance tuning, and cloud-based solutions.

Be Part of Our Success

  • Administer and maintain relational and distributed databases (e.g., PostgreSQL, HDFS) across multiple environments.
  • Implement database configurations, replication, and backups to ensure high availability and data integrity.
  • Participate in database design discussions — advising on schema, indexing, and partitioning strategies.
  • Perform query optimization and performance tuning to improve system efficiency.
  • Support data ingestion pipelines and integration with modern frameworks such as Apache Iceberg, Apache Hudi, GraphDB, or VectorDB.
  • Monitor and troubleshoot database performance and operational issues, escalating complex cases where needed.
  • Automate administrative tasks using Python, PowerShell, or Bash scripts.
  • Enforce security, access controls, and audit compliance in alignment with organizational policies.
  • Collaborate closely with developers, DevOps engineers, and data analysts to support product and feature development.

Qualities We Value

  • Minimum 4–5 years of experience in database administration, including hands-on experience with PostgreSQL or similar RDBMS.
  • Solid understanding of query tuning, indexing, and partitioning strategies.
  • Experience with distributed data or data lake frameworks (e.g., HDFS, Apache Iceberg, Apache Hudi).
  • Familiarity with scripting and automation tools (Python, Bash, PowerShell).
  • Exposure to graph or vector databases (GraphDB, Neo4j, VectorDB) will be an advantage.
  • Working knowledge of database security, access control, and backup/recovery best practices.
  • Strong analytical mindset, good communication skills, and a collaborative team player.

Our Commitment That Goes Beyond the Norm

  • An environment where you will be working on cutting-edge technologies and architectures.
  • Safe space where diverse perspectives are valued, and everyone's unique contributions are celebrated.
  • Meaningful work and projects that make a difference in people's lives.
