Role Title: Solution Architect – Azure Platform Migration Location: United Kingdom, India Client: Leading MNCs Mode: Hybrid (London, UK/ Hyderabad, India) Type: Contract - 6 Months extendable *Any one Certification is mandatory - AZ 305 or AZ 400 AZ 500*

*Job Description* We are seeking a senior Solution Architect to lead a high-priority migration of a retail group’s digital platform into a new group-wide Azure environment. This is a rebuild-from-scratch migration, not a lift-and-shift. The architect will conduct deep technical discovery across approximately 50 applications (including 20–25 Azure PaaS applications), identify architectural dependencies, and close the gap between board-level cost expectations and actual technical effort.

The role requires producing detailed Low-Level Designs (LLDs), leading a pilot migration to establish cost and effort benchmarks, and implementing a parallel migration strategy to ensure zero disruption to live systems. The architect will work alongside active development teams to ensure the migration progresses without impacting ongoing delivery.

*Key Responsibilities* Perform deep discovery and audit of 20–25 Azure PaaS applications. Analyse complex integrations including Azure Data Factory and Databricks. Develop Low-Level Designs maintaining Azure App Services, API Management, and Azure SQL architecture. Introduce new group standards including private endpoints and private DNS zones. Design and implement geo-replicated disaster recovery across UK South and UK West using an active-passive manual failover model. Design security integration with SAS Web Application Firewalls (WAF) in front of public-facing Application Gateways. Conduct code-level audits of .NET and TypeScript applications to identify hard-coded hostnames, IP addresses, and Key Vault references. Lead a pilot migration batch to benchmark effort, cost, and timelines for full-platform migration. Communicate technical risks, cost drivers, and resource requirements to senior leadership.

*Requirements* Extensive hands-on experience with Azure App Services, API Management, and Azure SQL Databases. Strong Infrastructure as Code expertise (Terraform preferred, Bicep acceptable). Deep understanding of private endpoints, subnet configuration, and private DNS zone management. Experience migrating large Azure SQL databases and managing cutover window constraints. Strong experience with CI/CD pipelines for multi-environment and multi-region deployments. Proven experience executing parallel migration strategies with zero-downtime cutovers. Strong stakeholder management skills with ability to justify architectural decisions to senior leadership. Software engineering background (preferably .NET) with ability to review source code dependencies.
