About the Job

The Capgemini Financial Services Open Banking Centre of Excellence (COE) partners with leading banks to transform their Digital Client Self Service capabilities through API-first cloud-native solutions. As a Solution Architect you will drive the design and delivery of end‑to‑end digital journeys that require extensive collaboration across groups and functions beyond Corporate Banking. You will play a central role in architecting self‑service capabilities such as CONA, sanctions and mandates journeys ensuring they are secure, scalable, compliant and optimised for a seamless customer experience.

Hybrid Working

The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of Company offices, client sites, and your home, noting that you will be unable to work at home 100% of the time.

Your Role

  • Digital Client Self Service Architecture
  • Lead solution architecture for digital client self-service capabilities enabling the client’s enterprise-wide permissions, mandates, sanctions checks and account services through intuitive digital channels
  • Define target state digital journeys and API-driven architectures that support straight-through real-time and self-service execution for corporate clients
  • End-to-end journey design with cross-group collaboration
  • Own architecture for complex E2E journeys requiring collaboration across the wider Group – retail, wealth, payments, compliance, operations and legal
  • Ensure all upstream and downstream dependencies are captured, orchestrated and aligned with regulatory, operational and customer experience expectations
  • Specialist journey ownership – CONA customer onboarding amendments
  • Architect the API workflow and data models enabling seamless client onboarding and profile amendments across multiple business lines
  • Sanctions journeys – design secure and compliant integrations with sanctions screening platforms ensuring adherence to regulatory obligations, rapid decisioning and traceability
  • Mandates authorisations
  • Define solutions for digital mandate management, including entitlement rules, signing authorities, approval workflows and auditability
  • Solution delivery governance – produce high-quality solution architecture artefacts (API specifications, integration maps, security patterns, sequence diagrams, logical and physical designs)
  • Engage stakeholders through workshops and design forums to align on solution direction and validate business and operational requirements
  • Present solutions to Architecture Review Boards and guide them through governance processes
  • Translate high-level journeys into iterative sprint-ready components in partnership with delivery leads
  • Review designs and code from engineering teams to ensure alignment with architecture principles and end-to-end journey intent
  • Ensure change requests remain aligned with solution integrity and strategic architecture
  • API cloud architecture responsibilities – apply best practices in REST API design, authentication and authorization security patterns, and microservices architecture
  • Promote enterprise-wide standards around API modelling, documentation, versioning and governance
  • Drive adoption of cloud-native approaches ensuring solutions leverage appropriate cloud services, resilience patterns and observability frameworks

Your Skills

  • Strong experience designing digital client self-service platforms, preferably in financial services or corporate banking
  • Proven delivery of E2E cross-functional journeys engaging multiple business units (operations, compliance, legal, customer servicing)
  • Experience architecting journeys related to onboarding, sanctions screening, mandates authorisation or similar regulated workflows
  • Deep knowledge of API architecture, REST design principles, Swagger/OpenAPI, RAML and API security standards
  • Familiarity with API management platforms (MuleSoft, Apigee, Kong, AWS API Gateway)
  • Hands‑on experience with microservices (Java, Spring Boot) and cloud-native deployment patterns
  • Strong understanding of OAuth2, OIDC, FAPI and enterprise security controls
  • Knowledge of observability and monitoring tools such as Splunk or ELK
  • Experience with public cloud platforms, ideally AWS
