Senior Software Engineer (Managed PostgreSQL)

About the role

Nebius is seeking a Senior Software Engineer to enhance their Managed PostgreSQL service for AI workloads. You will work across the stack, focusing on control plane automation, database performance, and migration tooling to support AI applications. The role involves both engineering development and operational responsibilities to ensure high-quality service delivery.

Responsibilities

• Develop the control plane and lifecycle automation for Managed PostgreSQL — provisioning, HA, failover, backups, PITR, version upgrades, zero-downtime maintenance.
• Tune and harden PostgreSQL itself — replication, WAL, vacuum, query planner, connection pooling, extensions — and turn that into product features and sane defaults customers don't have to think about.
• Build migration tooling that gets customers off AWS RDS, Google Cloud SQL, Azure Database for PostgreSQL, and self-managed clusters with minimal downtime.
• Drive the AI-Postgres story end to end — vector search (pgvector, pgvectorscale), hybrid retrieval, integration with the wider Nebius AI Cloud stack.
• Run the service like an SRE — define SLOs, build observability, lead incident response, feed every postmortem back into the platform.
• Work directly with customers on architecture reviews, performance escalations, and the production problems that don't fit a ticket template.
