Job description

Infrastructure Architecture and Design

Design and review infrastructure architectures for large-scale Internet services. Develop infrastructure designs covering compute, virtualization, networking, storage, operating systems and supporting infrastructure services. Design private virtualization and NFV environments for production Internet services. Define redundancy, fault tolerance and appropriate failure domains. Review infrastructure sizing, capacity, scalability and performance requirements. Ensure infrastructure designs support required service availability and performance objectives. Develop and maintain reference architectures and proven infrastructure design patterns.

Resilience and High Availability

Provide specialist expertise for services requiring continuous 24x7 operation. Design systems to eliminate or minimize single points of failure. Review high-availability, clustering and redundancy architectures. Assess infrastructure and component failure scenarios and their potential service impact. Review backup, restoration and disaster recovery strategies. Define appropriate recovery and service continuity approaches. Design and review infrastructure for stringent service availability requirements, including Five Nines (99.999%) availability where applicable. Ensure resilience considerations cover technology, operational processes and realistic failure scenarios.

Scalability and Performance

Provide infrastructure expertise for platforms supporting large subscriber populations and high service loads. Conduct capacity and growth planning. Define appropriate horizontal and vertical scaling strategies. Review infrastructure performance and resource utilization. Identify potential system and network bottlenecks. Review service dependencies and their impact on scalability and availability. Define appropriate monitoring and observability requirements. Ensure infrastructure can be expanded or upgraded while minimizing impact to production services.

Solution Design Assurance

Participate in Service Excellence technical governance for significant, complex or high-risk ISS projects. Review proposed solution architectures and infrastructure designs. Validate technical assumptions and dependencies. Identify architecture, resilience, scalability, security and operational risks. Assess whether proposed designs are practical to implement, operate and support. Review complex or non-standard infrastructure designs. Challenge technical assumptions constructively and recommend alternative approaches where appropriate. Verify that important operational considerations have been addressed before implementation.

Requirements

The Infrastructure Architect is expected to be a highly experienced technical professional with at least 10 years of relevant industry experience, including substantial practical involvement in: Infrastructure and solution architecture. Large-scale production system design. Implementation and commissioning. Infrastructure migration and transformation. High-availability systems. Production operations and troubleshooting. Performance and capacity engineering. Disaster recovery and service continuity. Major production incidents and root-cause analysis.
