Platform Architect: Unified Fintech Architecture Leader

Clune Tech Group; Ireland; On-site; EUR 120,000 - 180,000; Full time

Job summary

Fintua, part of CluneTech, is seeking a Principal Platform Architect to own the technical vision of our fintech platform, spanning greenfield design and modernization of production systems.

You will lead unified architecture, manage debt, and steer integration and data lake initiatives, ensuring security, observability and scalable data access.

This role requires a presence in Kilkenny, with a minimum of 2 days per week in the Kilkenny office, and collaboration across global teams.

Responsibilities

• Own end-to-end solution architecture across both new product initiatives and existing production systems, ensuring one coherent architectural vision rather than parallel, disconnected roadmaps
• Assess existing solutions (in-house and acquired/inherited) to identify architectural debt, integration gaps, and duplicated capabilities; define and prioritise a remediation roadmap
• Design new solutions to be integration-ready and debt-conscious from day one - avoiding the creation of tomorrow's legacy problems
• Define target-state architecture and phased migration paths that move legacy systems toward the target state without disrupting live operations
• Establish and enforce architectural guardrails - new and existing - must design against
• Define and drive architectural standards for AI and agentic capabilities across model integration, observability, auditability, security, and responsible AI controls, ensuring solutions are secure, well-engineered, and consistently designed across the enterprise.
• Build and maintain a technical debt register/inventory across the platform, with clear ownership, risk scoring, and business impact tied to each item
• Champion technical debt reduction as a first-class priority in planning cycles, not an afterthought - balancing it explicitly against new feature delivery
• Identify and eliminate redundant systems, data stores, and integration patterns as new solutions come online, rather than letting them accumulate alongside old ones
• Define "definition of done" standards that prevent new debt (test coverage, documentation, decoupling, observability) as part of every solution delivered
• Design the integration layer connecting internal solutions to each other and to external parties
• Establish consistent integration patterns (API-first) to replace ad hoc, point-to-point connections between systems
• Own API strategy and governance across the platform, ensuring internal and external interfaces are consistent, versioned, secure, and well-documented
• Act as the technical lead for evaluating and onboarding new external integrations and partners, assessing architectural and security fit before commitments are made
• Define the architecture and roadmap for a shared data lake enabling every solution on the combined platform to access underlying client data through governed, consistent interfaces
• Design the data model, ingestion pipelines, and access patterns so individual solutions can read data
