Senior PostgreSQL DBA | Scale & Automation Engineer

Workato; Portugal; Presencial; EUR 60 000 - 85 000; Tempo integral

Resumo da oferta

Workato is seeking a Senior PostgreSQL DBA to own data-layer operations across production clusters. You will design indexes, optimize queries on multi-terabyte datasets, manage Aurora PostgreSQL on AWS, and maintain connection pooling with PgBouncer.

You will split time between on-call support and longer-term reliability automation, collaborating with application teams on data-model decisions and implementing IaC with Terraform and Ansible.

Qualificações

• 5+ years of hands-on operational PostgreSQL experience (DBA / database reliability role).
• Strong command of query plans, indexing strategy, and performance work on multi-TB tables.
• Production experience with managed PostgreSQL (Aurora or RDS) and a clear-eyed view of its constraints.
• Working proficiency with Terraform and Infrastructure-as-Code practices; comfortable in Linux.
• Experience with connection pooling (PgBouncer or similar) in production.
• Practical experience with logical replication, major-version upgrades, and low-downtime migration techniques.
• Scripting ability (Bash, Python or GO) and an automation-first mindset.
• Experience with cloud infrastructure (AWS preferred); strong incident-management and RCA skills.

Responsabilidades

• Own day-to-day PostgreSQL operations across all production data centers: index creation on large/partitioned tables, query-plan analysis, schema reviews, data migrations.
• Partner with application teams on data-model decisions - design, partitioning, retention, consolidation vs. standalone clusters - and push back with data when a design won't scale.
• Operate and tune Aurora PostgreSQL: parameter groups, replicas, failover behavior, capacity planning.
• Run and evolve our PgBouncer connection-pooling layer.
• Turn manual runbooks into released, repeatable automation: seamless upgrade, switchover, database/user provisioning, grants management (Terraform + Ansible).
• Drive incident response and RCAs for database-related issues, and land the follow-up actions.
• Maintain and improve database observability (postgres_exporter, VictoriaMetrics dashboards and alerts).
• Take part in the team's duty rotation handling developer requests, with protected focus time off-duty.
