## About the Role

* 15+ years of experience in IT.
 * 8+ years in platform/solution architecture, including modern core banking in a U.S. banking context.
 * MUST HAVE Deep, hands-on knowledge of the Fiserv ecosystem
 * Finxact experience is strongly preferred (data model, parameterization, APIs, Config-as-Code).
 * Strong command of API-led/event-driven integration patterns and secure, high-volume data flows on AWS (API Gateway; Lambda/EventBridge/Kafka a plus).
 * Understanding of U.S. payments rails (Fedwire, ACH, RTP, FedNow), OFAC screening, cards and lending on a core platform.
 * Rigorous documentation discipline (ADRs, HLDs, data-flow maps); comfortable in a regulated, audit-driven environment.
 * Nice to have MuleSoft (or equivalent iPaaS/API management) experience.
 * At least one prior U.S. regulatory examination experience.
 * Bachelor's degree in Information Technology or related field.

## Description

* Own the architecture of the Fiserv/Finxact platform ecosystem: product-factory model, data model, parameterization limits, ledger/GL structure and Fiserv-native capabilities (payments rails, cards/lending).
 * Define how the Fiserv/Finxact platforms expose and consume APIs, setting integration contracts and standards at the boundary between Finxact and the rest of the ecosystem.
 * Serve as the technical authority on Finxact's operating model, what is achievable via configuration vs. code, and the Fiserv vendor roadmap - ensuring core decisions are defensible before a regulator.
 * Produce and maintain versioned Architecture Decision Records (ADRs) and current platform documentation - examination evidence expected by OCC/FFIEC .
 * Embed platform-level security, resilience and data-governance controls (RBAC/segregation of duties, encryption, audit trails, multi-region resiliency) aligned with InfoSec.
 * Act as the technical counterpart to Fiserv/Finxact and partners, validating solution architecture, configuration approach and delivery model against Itaú's reference architecture.
 * Partner with the Core Banking Engineering Lead, Config Specialists (Core/Deposits, Payments, Cards & Lending), Integrations and Release & Quality to ensure the platform architecture is buildable and audit-ready.
