Fintech Engineer

Overview

Fintech engineers build the systems that move money — payment rails, mobile wallets, lending platforms, and the ledgers that record every cent. The job exists at the intersection of distributed systems, financial regulation, and adversarial security: a single off-by-one in a ledger is a refund storm; a missed KYC check is a regulator fine. The role is large and growing in mobile-money markets (M-Pesa, MTN MoMo in Africa) and Latin American neobanks (Nubank, Mercado Pago), where billions of users transact daily through APIs that didn't exist a decade ago. SFIA 9 maps this cluster across BURM (business risk management), DESN (systems design), and SCTY (information security).

“You start the morning triaging an overnight reconciliation break — a card processor's webhook missed a refund event, and the ledger now disagrees with the acquirer's report by $1,432. You write a replay script, fix the drift, and add a guardrail. After standup, you scope a KYC pipeline upgrade so the compliance team can onboard SMEs in three more countries. Afternoon is split between reviewing a teammate's idempotency change to the payouts API, debugging why a fraud model is flagging legitimate Nigerian transactions, and writing the RFC for migrating internal messages to ISO 20022.”
