Senior Application Architect - Azure, Application Modernisation

Why This Role?

We're looking for a Senior Application Modernisation Architect to help organisations unlock greater value from their application estate. Working across both pre-sales and delivery, you'll engage directly with customers, shape modernisation strategies, influence technical decisions and help deliver transformational cloud-native solutions. This is an opportunity to combine architecture, consulting and hands-on technical expertise while helping build and grow a rapidly expanding practice.

What You'll Be Doing

Lead customer discovery workshops to understand application landscapes, business challenges and transformation goals
Shape application modernisation strategies and cloud adoption roadmaps aligned to business outcomes
Design modern application solutions leveraging Microsoft Azure and cloud-native technologies
Support technical sales activities through solution design, proposals, presentations and customer demonstrations
Develop Statements of Work including scope, assumptions, delivery approach and effort estimation
Conduct application portfolio assessments, dependency analysis and modernisation planning
Define migration and transformation approaches using recognised frameworks including 7Rs
Provide architectural guidance across modernisation and software development initiatives
Collaborate with architects, engineers and delivery teams to ensure successful implementation
Contribute to service development, sales enablement content, case studies and solution accelerators
