As a Database Administrator, you will be responsible for designing, deploying, maintaining, and monitoring production-grade databases across NoSQL and RDBMS environments. Your main duties will include optimizing database performance, query execution, and indexing strategies for large-scale datasets. You will also set up and manage replication, sharding, clustering, and backups for MongoDB and Elasticsearch, as well as configure PostgreSQL with custom parameters for tuning, connection pooling, WAL archiving, and recovery. Ensuring high availability and disaster recovery strategies are in place and regularly tested will be crucial, along with monitoring database health using tools like Prometheus/Grafana, Kibana, or custom scripts. You will need to implement security best practices, including access controls, encryption (TLS at rest/in transit), and auditing. Collaboration with DevOps and Development teams to support application performance and deployment cycles will also be part of your responsibilities. Automation will play a significant role in your daily tasks, as you will be required to write and maintain scripts using Bash, Python, or Ansible for provisioning and maintenance. Additionally, planning and executing major version upgrades and migrations with minimal downtime will be essential. Documenting configurations, architecture decisions, and standard operating procedures will be necessary to ensure smooth operations and knowledge sharing within the team. To qualify for this role, you should have 3-5 years of experience as a DBA or in a similar role managing MongoDB, Elasticsearch, and PostgreSQL. A solid understanding of data modeling principles across both NoSQL and SQL paradigms is required, along with expertise in replica sets, indexes, and aggregation pipelines in MongoDB. Proficiency in managing PostgreSQL installations, including roles, extensions (e.g., PostGIS, pg_stat_statements), and vacuuming strategies is essential. Preferred qualifications include PostgreSQL certification or equivalent experience, MongoDB DBA Certification, and experience with TimescaleDB, Redis, ClickHouse, or other database technologies. Familiarity with CI/CD pipelines, infrastructure as code (IaC), and working in cloud platforms like AWS, GCP, or DigitalOcean would be beneficial for this role. Strong analytical and problem-solving skills, along with a detail-oriented mindset, are key attributes for success in this position.,
