Senior PostgreSQL DBA/SRE (iPaaS, remote, FTE)

Locations: Spain, Bulgaria, or Portugal (relocation assistance may be provided).

Employment: Full-Time.

About the Company/Product:

• A global B2B product company developing a powerful Integration Platform as a Service (iPaaS) that uses AI and machine learning to enable organizations to seamlessly connect data sources, cloud applications, and enterprise systems through low-code/no-code automation.
• The platform handles mission-critical business logic and massive data flows for thousands of organizations worldwide, including Fortune 500 companies, global market leaders, and major tech giants.
• The engineering culture emphasizes technical excellence, strong ownership, and close collaboration across globally distributed, remote-first teams.

What You’ll Do:

We are hiring a Senior DBA/SRE to own the health, performance, and day-to-day operations of the PostgreSQL fleet behind the platform. The fleet is ~180 Aurora PostgreSQL clusters across production data centers worldwide. Some databases hold several terabytes, most clusters already run PostgreSQL 17, and the fleet is set to grow to a multiple of its current size. Your responsibilities may include:

• Keeping the Aurora PostgreSQL fleet healthy across all data centers: building indexes on large and partitioned tables without downtime, analyzing plans, and moving data.
• Handling Aurora configuration (parameters, replicas, failover, capacity) and cost work: rightsizing, merging low-activity databases, and evaluating serverless.
• Taking ownership of the PgBouncer layer, which currently needs an owner and a roadmap.
• Reviewing schemas and data models with product teams, and advising on partitioning, retention, and shared vs. dedicated clusters, backing recommendations with data.
• Working on the performance of the main application and the search queries behind AI features, including research toward a 10,000 jobs/second target.
• Packaging the team's existing zero-downtime upgrade and switchover procedures into versioned, released automation, along with provisioning of databases and users, grants, and schema sync across data centers (Terraform, Ansible, GitOps).
• Deploying tooling for monitoring and managing the PostgreSQL fleet in Kubernetes, and developing monitoring and alerting (exporters, VictoriaMetrics).
• Handling database incidents end-to-end, including root-cause analysis and follow-up fixes, and taking part in resilience projects: a cross-region DR pilot, application reconnect after failover, and CDC pipelines that survive upgrades and failovers.
• Contributing to time-boxed evaluations of new database technologies that end with a decision on what the company adopts.
• Participating in the on-call rotation, with off-rotation time going to uninterrupted project work.

Core Tech Stack: Aurora PostgreSQL, PgBouncer, AWS, Kubernetes, Terraform, Ansible, Linux, VictoriaMetrics, Vault.

What You Have:

• 5+ years of experience operating PostgreSQL in production (DBA, DBRE, or SRE with a database focus) on databases under real load.
• Deep experience with database schemas: design, debugging, and troubleshooting performance issues in production.
• SQL proficiency, query plans, indexing strategy, and performance work on multi-TB tables.
• Expertise in the ecosystem around PostgreSQL, not only the database itself: streaming and logical replication, HA and failover setups (Patroni or equivalent), connection poolers (PgBou
