Platform Architect

Fintua is a global leader in indirect tax compliance and tax technology. Our all-in-one platform streamlines global VAT compliance, recovery, eInvoicing and payments, helping businesses navigate the complex indirect tax landscape with ease and confidence.

Fintua is part of CluneTech, a suite of companies providing cutting-edge solutions that simplify global business. We have been recognised as a Great Place to Work for 11 consecutive years, a Best Workplace for Women for the past 7 years and most recently, a Best Workplace in Tech for the past 6 years.

This role requires a minimum of 2 days per week in our Kilkenny office.

We're looking for a Principal Platform Architect to own the technical vision and architectural integrity of our fintech platform — spanning both new solution design and existing systems already in production. This is a dual mandate: architect greenfield capabilities while simultaneously rationalizing and modernizing what's already built, so the platform grows as one coherent system rather than a collection of point solutions.

You'll be the primary technical authority ensuring that as we expand — new products, new markets, new acquisitions, new integrations — the platform stays unified, secure, and maintainable rather than accumulating fragmentation and technical debt.

A central focus of this role is seamless integration: making sure new and legacy solutions interoperate cleanly, share common data and identity models, and are built (or refactored) against a consistent set of architectural standards. You will also lead the strategy and implementation path toward a shared data lake / data platform, giving individual solutions across the combined platform governed, real-time access to underlying client data — eliminating duplicated data stores, inconsistent client views, and brittle point-to-point integrations between systems.

The Principal Platform Architect owns architecture strategy, standards and target-state design. Engineering Leads remain accountable for delivery execution and team management
