PostgreSQL

Key Responsibilities:

Database Installation & Configuration:

• Install and configure

  PostgreSQL databases

  in production and development environments.
• Perform

  database migrations

  from older systems or versions to the latest PostgreSQL versions.
• Set up

  replication

  and

  failover

  processes for high availability.

Database Maintenance & Administration:

• Monitor and ensure

  database performance

  is optimized (e.g.,

  query performance

  ,

  indexing

  ,

  disk I/O

  , etc.).
• Perform

  backup

  and

  restore operations

  to ensure data integrity and disaster recovery.
• Regularly update and patch the database to the latest version for security and performance.

• Data integrity checks

  ,

  data migrations

  , and management of

  schemas

  and

  tables

  .

Performance Tuning & Optimization:

• Use performance monitoring tools to identify and resolve performance issues such as slow queries and

  resource bottlenecks

  .
• Optimize SQL queries and

  database design

  to ensure efficient performance at scale.
• Create and maintain

  indexes

  and optimize the

  query execution plan

  for critical applications.

Security Management:

• Ensure the security of the database by managing

  access control

  ,

  user roles

  , and

  permissions

  .
• Implement

  encryption

  for data in transit and at rest.
• Regularly audit database access and activities to ensure compliance with security standards.

Replication & High Availability:

• Configure and maintain

  PostgreSQL replication

  (both

  master-slave

  and

  multi-master

  ) setups for high availability.
• Manage

  clustering

  and

  failover

  procedures to ensure database uptime.

Backup & Recovery:

• Implement a reliable

  backup

  strategy using tools like

  pg_dump

  ,

  pg_basebackup

  , or

  continuous archiving

  .
• Ensure

  point-in-time recovery

  (PITR) is set up and functional.
• Perform periodic testing of

  disaster recovery

  procedures.

Troubleshooting & Support:

• Provide day-to-day support for

  PostgreSQL databases

  including diagnosing and resolving database-related issues.
• Troubleshoot database

  connectivity issues

  , performance bottlenecks, and integrity problems.
• Respond to critical issues or outages promptly to restore database availability.

Collaboration & Documentation:

• Collaborate with development teams to optimize database queries and ensure database performance.
• Document database configurations, procedures, backup strategies, and any changes made to the system.
• Maintain clear and accurate records of database incidents, tickets, and resolutions.

Capacity Planning & Scalability:

• Plan for

  capacity

  and growth in database storage and resources to meet organizational needs.
• Perform scalability testing to ensure the database can handle increasing loads efficiently.

Required Qualifications:

• 2-5 years of experience

  as a

  PostgreSQL Database Administrator

  or similar database management role.
• Solid experience with

  PostgreSQL installation

  ,

  configuration

  , and

  maintenance

  .
• Proficient in

  SQL

  (including complex queries, joins, etc.) and

  PostgreSQL-specific functions

  .
• Hands-on experience with

  PostgreSQL replication

  ,

  clustering

  , and

  high availability

  setups.
• Experience with

  backup and restore strategies

  ,

  disaster recovery

  procedures, and

  point-in-time recovery

  .
• Strong troubleshooting skills for

  database performance

  issues, including

  query optimization

  and

  indexing

  .
• Experience with

  monitoring tools

  (e.g.,

  pgAdmin

  ,

  Nagios

  ,

  Prometheus

  ,

  Grafana

  ) to analyze database performance.
• Knowledge of

  security best practices

  and managing user roles and permissions in PostgreSQL.
• Familiarity with PostgreSQL

  extensions

  like

  PostGIS

  (for geospatial data) or

  pg_partman

  for partition management is a plus.
• Familiarity with

  cloud platforms

  (AWS RDS, Azure Database for PostgreSQL) is an advantage.
• Bachelor's degree in

  Computer Science

  ,

  Information Technology

  , or related field.
