Lydia operates a 100% mobile banking platform launched in 2011, built on React + TypeScript frontend infrastructure with Go and Python backend services, deployed on GCP. The hiring mix is heavily weighted toward sales (16 roles) and support (5) relative to engineering (5), with a majority of open positions at intern level — typical of a scaling fintech managing user growth and onboarding. Active projects center on regional commercial expansion and Sumeria card partnerships, while stated pain points indicate focus on distributed-system performance, fraud mitigation, and product-release reliability.
