The opportunityTechnology leaders are facing a new architecture problem.Cloud, data, AI, enterprise platforms and increasingly agentic systems can no longer be treated as separate transformation agendas. Decisions made across these layers determine an organisation's speed of innovation, technology economics, resilience, interoperability and ability to scale AI safely.Deloitte Africa Engineering, AI & Data Advisory is looking for an exceptional Senior Manager – Platform, Architecture & Modernisation Advisory to help executives navigate these decisions and translate them into executable transformation programs.This is not a conventional enterprise architecture or solution architecture role.It is a senior consulting and practice-building position for someone who can challenge technology strategy, make complex architecture choices understandable to executives, create investable modernisation pathways and mobilise engineering teams to execute them.Your mandateAs capability steward, you will build and lead Deloitte Africa's Advisory proposition around the technology foundations required for modern digital and AI-enabled enterprises.You will connect strategic intent to the architecture decisions required to make it real.Your mandate spans:Technology decision advisory.
