Infrastructure Architect

Key Responsibilities
Infrastructure Architecture & Planning

• Define and maintain the target-state infrastructure architecture across data centres, cloud platforms, and edge environments.

• Lead the roadmap for infrastructure modernization including virtualization, hyperconverged systems, containerization, and network overlays.

• Establish infrastructure patterns and blueprints for compute, storage, backup, disaster recovery (DR), and network architectures.

• Align infrastructure strategy with enterprise architecture principles, performance objectives, and service-level agreements (SLAs).

Cloud and Hybrid Enablement

• Drive hybrid and multi-cloud architecture strategy across AWS, Azure, and private cloud (e.g. Open Stack, VMware).

• Architect secure, compliant infrastructure-as-code pipelines, integrating Terraform, Ansible, or similar tools.

• Guide cloud landing zone design, VPC architecture, identity federation, and interconnect strategies.

• Ensure observability, cost governance, and elasticity in cloud-native workloads.

Security, Resilience & Compliance

• Embed security-by-design principles into infrastructure blueprints, including micro segmentation, encryption and zero-trust access.

• Architect HA/DR solutions across critical systems, ensuring geographic redundancy and failover readiness.

• Ensure infrastructure compliance with PCI-DSS, ISO 27001, and local regulatory requirements.

• Support infrastructure risk assessments and penetration testing preparation.
Governance & Collaboration

• Participate in Architecture Review Boards to assess infrastructure impact and conformance to strategy.

• Collaborate with Dev Ops, SRE, security, and operations teams to promote infrastructure reliability and automation.

• Engage with vendors, cloud providers, and technology partners for capability assessment and solutioning.

• Produce and maintain infrastructure architecture documentation, standards, and runbooks.

Key performance indicators
Infrastructure Strategy & Alignment

• Deliver infrastructure blueprint aligned to EA target architecture within 90 days.

• Define scalable deployment topologies for critical systems (e.g., mobile money platforms, APIs, microservices clusters).

• Champion use of infrastructure blueprints and reusable templates to reduce config drift and accelerate onboarding.

Cloud Modernization & Optimization

• Enable at least 3 legacy workloads for cloud readiness with full infra-as-code deployment.

• Design secure, multi-cloud landing zones with federated identity, policy enforcement, and network segmentation.

• Develop migration playbooks and automated cutover strategies to enable safe cloud transitions.
Resilience, DR, Security & Observability

• Deploy observability and automation across ?60% of critical systems.

• Establish platform SLAs and work with Tech Ops to monitor, improve uptime and performance.

• Ensure all infra configs comply with internal baselines and pass automated security scans.

• Integrate infra security with SIEM, SOAR, and vulnerability tools in collaboration with cybersecurity teams.

Technical Experience:
Essential:

• 8+ years in infrastructure or cloud architecture roles in high-availability environments.

• Strong background in data center and cloud network architecture, compute and virtualization, storage and backup, hybrid cloud design, IaC and automation, CI/CD and infrastructure observability.

• Experience with platform engineering, service mesh, and secure enclave deployment.

• Familiarity with Fintech or payments-grade infrastructure standards.

• Clear understanding of layered security, zero trust, and identity federation.

• Demonstrated hands-on experience architecting

Infrastructure: 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.

• Strong experience in designing…
