Key Responsibilities

• Configure MongoDB replica sets and sharded clusters based on application requirements to ensure optimal performance and reliability.
• Set up MongoDB Backup and Restore Service (BRS) and Ops Manager, onboarding replica sets and sharded clusters for monitoring and management.
• Implement security measures, including X.509 and TLS authentication, to comply with industry standards, such as those set by Apple.
• Automate backup, restore, and monitoring processes using Python and shell scripting to streamline database management.
• Design, install, and configure multi-node MongoDB sharded clusters and replica sets on Linux platforms. Add or remove replica and shard nodes as required.
• Create text indexes for querying specific documents with string content and ensure optimal shard key selection for even data distribution.
• Convert replica sets to sharded clusters to accommodate data growth and improve query performance.
• Manage upgrades and migrations of replica sets and sharded clusters, specifically from version 4.0 to 4.xx.
• Deploy, migrate data, monitor system performance, analyze usage patterns, and tune MongoDB instances for optimal performance.
• Maintain in-depth knowledge of Ops Manager, including upgrades, group and project configurations.
• Configure SSL key files to enhance security across all MongoDB instances.
• Document MongoDB installation processes, operational procedures, security measures, and auditing practices across multiple environments.
• Analyze query plans, optimize performance at both host and database levels, and implement effective sharding strategies (range-based and hash-based).
• Oversee the migration of MongoDB clusters to AWS, ensuring a seamless transition with minimal downtime.
