ING Poland is a 5,000+ person banking operation migrating core infrastructure to public cloud (GCP, Azure, AWS) while phasing out Hadoop/Cloudera — a multi-year modernization that spans data architecture, retail product development (embedded finance, credit cards), and customer-facing digitalization. The hiring mix (finance, engineering, sales, product, data) reflects simultaneous regulatory compliance work and expansion into advisory services, with intern-to-senior ratios suggesting knowledge transfer as legacy systems transition.
