## About the Role

We are looking for a Senior Cash & Banking Architect to join a major financial services organisation and support the modernisation of its Cash & Banking technology landscape.

This is a senior architecture role sitting at the intersection of payments, cash management, treasury and technology architecture. You will help shape the future architecture of business-critical banking platforms while working across both modern and legacy technology environments.

We are particularly interested in candidates with strong experience in payments and cross-border payments, who understand the end-to-end payment lifecycle and can translate complex business requirements into scalable technology solutions.

You do not need previous experience within this organisation or detailed knowledge of its existing cash platforms. A strong foundation in payments, banking and architecture is the priority., Payments & Banking

 * Strong experience within the payments domain.
 * Good understanding of cross-border/international payments.
 * Understanding of the complete payment lifecycle through to clearing and settlement.
 * Experience with SWIFT messaging.
 * Knowledge of ISO 20022 and modern payment messaging standards.
 * Familiarity with legacy SWIFT MT messaging alongside newer MX/ISO 20022 standards.
 * Knowledge of cash management and/or treasury concepts.

 * Strong understanding of event-driven architecture.
 * Experience designing API and microservices-based architectures.
 * Strong enterprise integration knowledge.

 * Understanding of integration between mainframe and open-system environments would be advantageous but is not essential.
 * Experience modernising legacy banking or payments platforms would be highly desirable.

Leadership & Stakeholder Management

This is not simply a technical design position. We are looking for an architect who is comfortable operating at a senior level and influencing important technology decisions.

 * Lead architecture and solution-design workshops.
 * Facilitate discussions between business and technology teams.
 * Clearly explain complex architecture decisions.
 * Challenge existing approaches constructively., * Cash Management
 * Treasury Technology
 * Financial Market Infrastructure
 * Clearing & Settlement
 * Post-Trade Technology
 * Banking / Payments Transformation
 * Financial Services Consulting

Previous experience within a CSD or financial-market infrastructure organisation would be valuable, but is not a prerequisite.

## Description

* Define and shape architecture across cash, payments and treasury platforms.
 * Support the modernisation of existing banking and payment systems.
 * Provide architecture expertise across the end-to-end payment lifecycle, including payment initiation, processing, clearing and settlement.
 * Design solutions using event-driven architectures, APIs and microservices.
 * Define integration patterns across multiple platforms and technology environments.
 * Work with both modern platforms and established/legacy banking systems.
 * Support the evolution from legacy messaging and integration approaches towards modern standards and architectures.
 * Lead architecture workshops and working sessions with business and technology stakeholders.
