Infoplus Technologies UK Limited; Greater London; On-site; GBP 90,000 - 130,000; Full time

Job summary

Infoplus Technologies UK Limited is seeking a Solution Architect to govern the end-to-end architecture for a debit-card platform integration within a leading UK banking environment. The role spans design across cloud and on-premises, connecting card-management, payment-gateway and core banking services via APIs, events and batch interfaces.

You will drive architecture decisions, define integration patterns for REST/SOAP, and ensure security, resilience and production-readiness across multiple

Qualifications

• Strong experience designing large-scale enterprise solutions in banking, cards, payments or core-banking integration.
• Architecture expertise across APIs, microservices, event-driven services and batch integration patterns.
• Hands-on knowledge of Java and Spring Boot solution ecosystems, with the ability to guide engineering design and implementation.
• Experience designing solutions on Google Cloud Platform and Kubernetes-based platforms, including hybrid cloud and on-premises integration.
• Strong understanding of API management and security, integration gateways, authentication, encryption and secrets management.
• Experience with Kafka or equivalent event-streaming platforms, cloud storage and data-integration patterns.
• Experience producing architecture artefacts and presenting solution decisions to engineering, security, infrastructure and governance stakeholders.
• Knowledge of CI/CD, automated quality controls and operational tooling such as Jenkins, Harness, Splunk or Dynatrace.
• Effective stakeholder communication, facilitation and technical leadership across multi-disciplinary and distributed teams.
• Ability to define and assure non-functional requirements for availability, resilience, scalability, latency, security, observability and recoverability.
• Knowledge of debit-card lifecycle journeys, card ordering, lost-and-stolen servicing, PIN management, voice authorisation, renewals and reissue processes.
• Experience integrating legacy mainframe or card platforms using SOAP, ISO 8583, files and modern API or event-based patterns.
• Knowledge of Apigee, HashiCorp Vault, Google Cloud Storage, OpenShift or equivalent technologies.
• Familiarity with financial-services architecture governance, security controls and production-readiness processes.
• Understanding of BIAN-aligned APIs or enterprise data-model standards.

Responsibilities

• Own the end-to-end solution architecture for the TM-Vault integration, covering lookup services, the core-banking integration layer and changes across card-management, payment-gateway and clearing systems.
• Translate business outcomes and functional journeys into target-state architecture, solution designs, interface specifications and delivery roadmaps.
• Define integration patterns for REST and SOAP APIs, event-driven interactions and batch processing across cloud and on-premises environments.
• Lead architecture decisions for hosting, data movement, caching, orchestration, resilience, security, performance and observability.
• Produce and govern architecture artefacts, including high-level and low-level designs, interface contracts, data flows, non-functional requirements and architecture decision records.
• Work with product owners, integrators, engineers, DevOps, QE and service teams to shape the backlog and ensure design intent is maintained through build, test and release.
• Coordinate with dependent platform teams and architecture forums to resolve cross-system dependencies and secure required approvals.
• Assess legacy integration constraints and define pragmatic transition approaches that minimise throwaway change and support coexistence during migration.
• Provide technical assurance through design reviews, implementation oversight, risk management and production-readiness assessments.
• Support knowledge transfer, documentation and handover to engineering and service teams, including operational monitoring and support requirements.
