Senior Software Engineer (Managed PostgreSQL)

About Nebius

Nebius is leading a new era in cloud infrastructure for the global AI economy, building a full-stack AI cloud platform. Listed on Nasdaq (NBIS) and headquartered in Amsterdam.

The Role

We're looking for a Senior Software Engineer to help build the best Managed PostgreSQL for AI workloads — first-class vector search, painless migrations from RDS/Cloud SQL/self-managed clusters, and the operational quality of a mature managed database. You'll work across the stack: control plane and lifecycle automation in Go, Postgres internals and performance, and migration tooling. You're welcome to work from the Amsterdam or London offices, hybrid or remotely from EU timezones.

Your 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.
• Build migration tooling that gets customers off AWS RDS, Google Cloud SQL, Azure Database for PostgreSQL, and self-managed clusters.
• Drive the AI-Postgres story end to end — vector search (pgvector, pgvectorscale), hybrid retrieval.

Nice to Haves

Experience with pgvector/pgvectorscale at scale, background building managed-database control planes (RDS, Cloud SQL, Aiven, Crunchy, Timescale, Supabase, Neon), Kubernetes operators (Go + controller-runtime/kubebuilder), and contributions to PostgreSQL or its extensions.
