Architecture Strategy & Planning

  • Develop and evolve the enterprise architecture blueprint, frameworks and target-state architecture, ensuring alignment with long-term business objectives and future-state technology vision.
  • Define and maintain architectural principles, domain strategies, and standardized reference models that support scalable, interoperable, and secure technology ecosystems.
  • Translate corporate strategy, regulatory mandates, and digital transformation goals into clear architectural initiatives and target-state designs.
  • Lead multi-year roadmap development across technology domains including applications, data, integration, infrastructure and security in collaboration with domain architects and delivery teams.
  • Continuously assess technology trends and emerging innovations to guide modernization and strategic platform selection.


Governance & Oversight

  • Chair Architecture & Design Review Boards (ARBs) to review, guide, and approve solution designs, ensuring consistency with enterprise standards and strategic objectives.
  • Define governance processes for architectural compliance, exception management, and deviation tracking across business portfolios and technical teams.
  • Perform architecture assurance and gap assessments to identify technical risk, misalignment, and opportunities for consolidation or optimization.
  • Ensure ongoing enforcement and evolution of architecture policies, design standards, and lifecycle documentation for all enterprise assets.
  • Support audit readiness and regulatory compliance by embedding architecture governance in change delivery.


Collaboration & Stakeholder Engagement

  • Act as a strategic advisor to Head of Architecture, shaping investment decisions and prioritizing technology initiatives based on architectural insights.
  • Work closely with product managers, domain architects, engineers, and business analysts to co-create architectural solutions that meet functional and non-functional requirements.
  • Build alignment across multiple delivery streams and business units to ensure architecture decisions enable reusability, resilience, and cost-effectiveness.
  • Facilitate cross-functional design workshops, architecture forums, and technical deep-dives to enable shared understanding and decision-making.
  • Represent the enterprise architecture function in vendor evaluations, technology partnerships, and RFP/RFI processes.


Architecture Delivery

  • Lead the design and evolution of enterprise-scale platforms, including cloud-native systems, Payment Systems, API gateways, service orchestration layers, event-driven architectures, and data lakes.
  • Guide the definition of architecture enablers and technical epics within agile planning cycles
  • Ensure timely delivery of architecture artifacts and technical blueprints to support sprint-level execution and platform runway readiness.
  • Monitor implementation of architectural designs to ensure conformance with standards and provide hands-on support in resolving complex design challenges.
  • Foster DevSecOps and platform engineering practices by integrating architecture with CI/CD pipelines, security automation, and observability frameworks.


Technical Experience:

  • Proven track record in defining and evolving enterprise-wide architecture strategies, reference models, and technology roadmaps.
  • Deep understanding of enterprise architecture frameworks such as TOGAF, Zachman, or FEAF, and experience applying them in complex organizations.
  • Experience driving architecture transformations aligned to digital business models (e.g., omnichannel, platform as a service, composable architectures).
  • Demonstrated hands-on experience architecting across multiple domains, including:
    • Applications: Monolith to microservices decomposition, modernization, and lifecycle management.
    • Data: Master Data Management (MDM), data lakes, streaming pipelines (e.g., Kafka), and analytics platforms.
    • Integration: API-led design (REST, GraphQL), event-driven architecture, service mesh, and ESB replacement strategies.
    • Infrastructure & Cloud: Hybrid/multi-cloud architectures (AWS, Azure, GCP), container orchestration (Kubernetes), IaaS/PaaS adoption models.
  • Deep understanding of architectural implications for regulatory compliance frameworks (e.g., PCI-DSS, GDPR, ISO 27001).
  • Experience integrating Zero Trust Architecture, identity management (OAuth2, OpenID, SAML), and encryption protocols into enterprise design.
  • Familiarity with architecture risk assessments, threat modelling, and secure-by-design principles.
  • Experience of various software engineering playbook frameworks (Agile development, Automated testing, Code reviews, Continuous delivery, Continuous integration, Machine learning. Observability, Privacy, Reliability, Security)
  • Strong experience in designing high traffic, scalable, reliable, and secure software systems.
  • Knowledge of architectural styles and patterns (e.g., Microservices, SOA, MVC, Event-driven architecture).
  • Understanding of cloud architecture and services (e.g., serverless computing, containerization, orchestration).
  • Experience with data modelling, data warehousing, and data integration.
  • Experience in Mobile App Development and Mini-app Frameworks
  • Experience with architectural modeling tools (e.g., ArchiMate, Sparx EA)
  • Experience leading or supporting large-scale modernization or transformation programs (e.g., core banking revamp, mobile money overhaul, ERP replacement).

Desirable

  • Experience of continuous delivery and release automation processes.
  • Experience in Blockchain Software Architecture, AI/ML-driven decision systems, edge computing, etc
  • Experience in Orchestration Architectural Patterns
  • Knowledge and interest in market leading Payments technologies, suppliers and innovations
  • Understanding of technical and architectural policies and ability to transform that policy into detailed technical design.
  • Experience in Vendor assessment and technical due diligence for major platform selections.
