About the role

Key responsibilities & impact

Own the end-to-end solution architecture for complex, business-critical payment capabilities across multiple products, services, channels, and integration points
Define current, target, and transition architectures, and maintain technology roadmaps that guide platform modernisation and investment decisions
Turn business, product, regulatory, security, and operational needs into architecture principles, solution designs, and practical guidance for delivery teams
Lead architecture governance by creating and reviewing solution proposals, architecture decisions, interface specifications, and other key design documents
Define responsibilities for services and establish integration patterns for APIs, event-driven messaging, and batch processing
Ensure solutions meet requirements for resilience, availability, performance, scalability, observability, security, operability, upgradeability, and backward compatibility
Collaborate with product management, engineering, security, operations, and client-facing teams to resolve cross-functional trade-offs and align priorities
Provide architectural leadership for strategic client engagements, proposals, and complex implementations, presenting options and recommendations to technical and executive audiences
Support delivery teams during implementation, confirm adherence to agreed designs, and address significant departures from target architecture or enterprise standards
Mentor architects and senior engineers, strengthen architecture practices, and serve as a recognised authority on payments and platform architecture

Requirements

What you’ll need

Extensive experience designing and delivering enterprise-scale software platforms throughout the development lifecycle, from iterative delivery to production deployment
Proven experience leading the architecture of complex, distributed, microservices-based systems across multiple teams and organisational boundaries
Demonstrated ownership of end-to-end solution architecture, target-state roadmaps, architecture governance, and major technical decisions
Deep knowledge of API design, event-driven architecture, domain-driven design, service decomposition, and systems integration
Strong understanding of distributed systems, including data consistency, idempotency, fault tolerance, circuit breaking, asynchronous processing, and backward-compatible change
Strong technical expertise in Java and JVM-based enterprise platforms, relational databases such as Oracle or PostgreSQL, and modern software delivery practices
Experience designing secure, resilient, highly available, scalable, observable, and operationally manageable systems for business-critical environments
Ability to influence senior stakeholders, guide decisions where priorities compete, and explain complex architecture clearly to technical and non-technical audiences
Track record of leading architecture across several concurrent initiatives and mentoring architects, technical leads, and engineering teams
Sound judgement when assessing architecture options in terms of business value, risk, cost, delivery impact, and long-term maintainability
Working knowledge of Agile delivery at scale and the ability to work effectively in organisations that use both iterative and plan-driven delivery models
Deep knowledge of financial services and payments, including payment orchestration, clearing and settlement, payment networks, SWIFT, and ISO 20022
Experience modernising large payment platforms and defining clear responsibilities across payment initiation, payment execution, and integration services
Experience with event streaming, event sourcing, CQRS, workflow modelling, and API specifications using technologies or standards such as Kafka, BPMN, OpenAPI, and YAML
Experience with container platforms and cloud-native architecture, including Docker, Kubernetes, and public, private, or hybrid cloud environments
Knowledge of distributed data platforms, including relational, NoSQL, and horizontally scalable databases
Experience creating architecture views such as context, container, sequence, domain, and deployment diagrams
Understanding of platform engineering and delivery practices such as infrastructure automation, contract testing, end-to-end testing across products, distributed tracing, and automated provisioning
Broad knowledge of infrastructure architecture, including networking, compute, storage, databases, security, middleware, identity, and systems management
