Job description

1. 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.

2. Resilience and High Availability

• Provide specialist expertise for services requiring continuous 24×7 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.

3. 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.

4. 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.
