Database Administrator (DBA) – PostgreSQL / AWS

Job Mission

We are looking for a DBA with solid PostgreSQL fundamentals, a curious and analytical mindset, and a strong willingness to develop their expertise alongside an experienced DBA. The candidate will be responsible for administering, monitoring, and optimizing our databases, particularly in mission-critical, high-volume transactional production environments.

The candidate will work closely with development, architecture, and production teams, as well as an experienced DBA who will provide guidance and mentorship on advanced PostgreSQL and AWS topics.

Key Responsibilities

• Administer and maintain PostgreSQL databases (configuration, backups, recovery, monitoring).
• Monitor database performance and participate in investigating and resolving production incidents.
• Analyze and optimize SQL queries, indexes, and execution plans (EXPLAIN / ANALYZE).
• Identify connection issues, long-running transactions, locks, and resource consumption bottlenecks.
• Participate in database maintenance and optimization activities (VACUUM, AUTOVACUUM, PostgreSQL statistics).
• Work with AWS database services and monitoring tools, including RDS / Aurora PostgreSQL, CloudWatch, and Performance Insights / Database Insights.
• Contribute to technical improvements, including partitioning, data volume management, migrations, and performance optimization.
• Participate in advanced investigations (XID wraparound, idle in transaction, bloat, contention), with guidance from experienced technical team members.
• Document incidents, technical analyses, and operational procedures.

Candidate Profile

Degree in Computer Science, IT, or a related field, with at least 5 years of experience in database administration.

Required Skills

• Good hands-on knowledge of PostgreSQL, preferably in production environments.
• Strong SQL skills and a good understanding of query optimization and indexing.
• Understanding of transactions, locking mechanisms, and PostgreSQL maintenance processes.
• Experience in database monitoring, troubleshooting, and incident resolution.
• Good knowledge of Linux/Unix environments.

Preferred Skills

• Experience with AWS RDS / Aurora PostgreSQL, CloudWatch, Performance Insights, and RDS Proxy.
• Familiarity with partitioning, VACUUM / AUTOVACUUM, and large database management.
• Basic understanding of replication, high availability, and disaster recovery.
• Knowledge of Oracle Database (a plus, not mandatory).
• Experience in banking or high-volume transactional environments.

Personal Attributes

• Strong analytical and problem-solving skills, with a structured approach to technical investigations.
• Self-motivated, curious, and eager to learn.
• Ability to collaborate effectively with development and production teams.
• Fluency in English (written and spoken) is mandatory, with the ability to communicate effectively in technical discussions and collaborate with international teams.

We value candidates with strong PostgreSQL fundamentals and a genuine willingness to learn and grow, rather than those who already master every advanced technical topic listed above.
