EPI Company Tech Stack

European payments infrastructure and digital wallet platform

Financial Services Brussels, Brussels Region 201–500 employees Founded 2020 Privately Held

EPI operates as the technical and operational backbone of Wero, a pan-European digital wallet backed by 16 major banks. The stack—Kotlin, Java, Kubernetes, AWS, MongoDB—reflects a modern microservices architecture built for scale, while active hiring skews heavily toward senior engineers and product (69 senior, 22 lead roles across 126 open positions) rather than sales, suggesting a product-first, infrastructure-heavy organization. Current project work centers on payment settlement, fraud detection, GDPR/PSD2 compliance, and wallet integration—signaling execution across both core platform stability and regulatory complexity.
