Key Responsibilities

•Design, develop, and maintain high-quality applications using React.
•Scale and tune high-throughput PostgreSQL clusters that support continued global expansion and new product initiatives.
•Own PostgreSQL reliability fundamentals: WAL behavior, checkpoints, autovacuum, query planning, locking, replication lag, backup/restore, and capacity planning.
•Help build and operate vector data capabilities, including pgvector and dedicated VectorDB platforms where appropriate.

•Experience with connection pooling and traffic management for PostgreSQL, especially PgBouncer, HAProxy, Kubernetes service routing, or comparable patterns.
•Practical VectorDB or vector search experience, such as pgvector, Qdrant, Milvus, Weaviate, OpenSearch vector search, or similar systems.
