FYST is a payment infrastructure company built on a modern polyglot stack (Node.js, Go, Python, PostgreSQL, Kafka, Kubernetes) with heavy investment in observability (Grafana, Loki, Jaeger, Tempo). The hiring velocity is accelerating across engineering (41 open roles), finance (19), and legal (17) — a mix that reflects the dual challenge of scaling a fintech platform while managing regulatory complexity. Pain points cluster around building payment processing from scratch, compliance with card-network mandates, and data synchronization — all typical of a young payments company bridging custom merchant needs with Visa/Mastercard rails.
