Senior Database Engineer

Why this role matters As a Senior Database Engineer at Exness, you will join a senior team of database engineers and platform engineers responsible for the company’s large-scale database and data platform infrastructure. The team operates hundreds of production database clusters across PostgreSQL, MongoDB, ClickHouse, Cassandra, and other distributed data systems powering critical global workloads.
