Financial Services Buenos Aires 201–500 employees Founded 2021 Privately Held

Pomelo operates a card and payment infrastructure platform serving Latin American financial institutions. The tech stack reflects a mature, compliance-heavy ops posture: Splunk, Sentinel, Elasticsearch for observability; AWS, GCP, Azure for distributed deployment; and core services in Java, Go, and Kotlin. Active hiring across engineering, legal, and security—with security representing 22% of open roles—signals both regulatory scrutiny and a platform scaling from startup to operational rigor. Projects center on credit backend hardening, payment processor maturation, and RSOC buildout, while pain points cluster around legacy infrastructure migration and regulatory monitoring.
