About The Position

ITTConnect is seeking a Fiserv platform expert for a direct-hire, full-time position with a client in Miami. The Core Banking Platform Architect owns the architecture of the Fiserv/Finxact platform ecosystem, including its product-factory model, data model, parameterization limits, ledger and general-ledger structure, and native capabilities for payments, cards, and lending. The architect defines API exposure and consumption, integration contracts, and standards at the boundary between Finxact and the broader ecosystem.

The role serves as the technical authority on Finxact’s operating model, configuration-versus-code capabilities, and the Fiserv vendor roadmap. It produces and maintains versioned Architecture Decision Records and current platform documentation to support OCC/FFIEC examination evidence. The architect embeds security, resilience, and data-governance controls aligned with InfoSec, acts as the technical counterpart to Fiserv/Finxact and delivery partners, and collaborates with engineering, configuration, integration, and release teams to ensure the architecture is buildable and audit-ready.

Requirements

• 15+ years of experience in IT.
• 8+ years in platform or solution architecture, including modern core banking in a U.S. banking context.
• Deep, hands-on knowledge of the Fiserv ecosystem.
• Strong command of API-led and event-driven integration patterns and secure, high-volume data flows on AWS.
• Understanding of U.S. payments rails (Fedwire, ACH, RTP, FedNow), OFAC screening, cards, and lending on a core platform.
• Rigorous documentation discipline, including ADRs, HLDs, and data-flow maps; comfort working in a regulated, audit-driven environment.
• At least one prior U.S. regulatory examination experience.
• Bachelor’s degree in Information Technology or a related field.

Nice To Haves

• Finxact experience, including its data model, parameterization, APIs, and Config-as-Code.
• AWS experience with API Gateway; Lambda, EventBridge, or Kafka experience is a plus.
• MuleSoft or equivalent iPaaS/API management experience.

Responsibilities

• Own the architecture of the Fiserv/Finxact platform ecosystem, including the product-factory model, data model, parameterization limits, ledger/GL structure, and Fiserv-native capabilities for payments, cards, and lending.
• Define how Fiserv/Finxact platforms expose and consume APIs, including integration contracts and standards between Finxact and the broader ecosystem.
• Serve as the technical authority on Finxact’s operating model, configuration-versus-code capabilities, and the Fiserv vendor roadmap; ensure core decisions are defensible before regulators.
• Produce and maintain versioned Architecture Decision Records (ADRs) and current platform documentation as examination evidence for OCC/FFIEC.
• Embed platform-level security, resilience, and data-governance controls—including RBAC, segregation of duties, encryption, audit trails, and multi-region resiliency—in alignment 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, configuration specialists, Integrations, and Release & Quality to ensure platform architecture is buildable and audit-ready.
