Banking Tallinn, Harju 1,001–5,000 employees Founded 2017 Privately Held

Luminor operates a regional bank serving ~870,000 clients across Estonia, Latvia, and Lithuania with an engineering-forward organization actively migrating from legacy monoliths to cloud-native infrastructure. The tech stack shows mature data (Kafka, Spark, Airflow, dbt, Snowflake, BigQuery) and shifting application security posture (adopting SAST/DAST/IAST, integrating CI/CD controls), while active hiring in engineering (75 roles), data (36), and security (28) signals a multi-year infrastructure modernization tied to regulatory compliance — anacredit, corep reporting, and PCI-DSS are core project drivers, not afterthoughts.
