• Manage own delivery against the strategic architectural roadmap delivery plan by planning and managing business projects as per set protocols and SLA's.
• Measure and monitor risks to the business by conducting reviews on the resiliency of the solution design, ensuring monitoring and system alerts measures are included as part of the solution design.
• Assume accountability for 3rd Level Escalation BAU support to resolve complex problems and provide 1 day a week routine BAU support.
• Write functional requirement/specification documents for technology solutions that meet the intended business requirements including relevant measurement criteria that determine success.
• Ensure that architecture principles and technology standards are consistently applied and updated appropriately and stored in the Technology Reference Model.
• Ensure that all solution designs across all Linux infrastructure platforms going into production have supporting documentation on necessary controls/alerts, contain implementation guidelines, show alignment to the intended operational processes and procedures that will ensure operational readiness at time of handover.
• Ensure all subsequent reported changes to the in-production Linux Infrastructure designs are captured and that documentation of present state designs are updated with a validation of adequacy of solution design controls and alerts.
• Take accountability for ensuring the documentation of the Technology Reference Models (TRM) of the present and future state Linux technology infrastructure architecture as well as design and implementation of the plans to transition to the future state architecture are updated and included in the TRM.
• Conduct market research prior to making recommendations on compute products, services, protocols, and standards in support of the compute procurement and development efforts.
• Perform compute analysis to ensure the design solution meets business requirements by developing and deploying tests and providing statistics and reports measuring performance and effectiveness of solution.
• Identify system optimisations and improvements in both technology and processes that are needed in the current Linux compute and storage infrastructure to ensure high performance and high availability of systems.
• Troubleshoot problems with team members to identify root cause system inefficiencies to ascertain best route of action (i.e. system problem or change in environment due to increased trading)
• Collaborate with other subject matter experts on critical IT projects to ensure that compute issues are addressed throughout the whole project life cycle and measure the impact on business of solution by reviewing test results.
• Take a leadership role in infrastructure projects to design and engineer large scale implementations.
• Analyse existing compute structures to define, design and achieve simplified, modern, application-focused compute architecture's that meet long and short-term goals of the business.
• Take accountability to ensure disaster recovery, BCP (Business Continuity Planning) and security measures are taken into consideration in all solution design processes and that support documentation is provided.
• Maintain all existing and "to be" compute artefacts in the Enterprise Architecture Tool.
