About the Client  

Join a high-impact modernization initiative for a leading UK PropTech company, where you’ll help transform a mission-critical legacy SaaS/TOM platform into a modern, scalable solution. You’ll dive deep into classic .NET monolith code to uncover and reshape complex business logic—an engaging challenge for engineers who love problem-solving at the architectural level. 

This project offers the rare opportunity to rebuild both backend and frontend from the ground up using modern frameworks, cloud-ready patterns, and clean architecture principles. Expect a strong focus on engineering excellence: analytics and monitoring instrumentation, automated testing, CI/CD maturity, and maintainable code quality. If you want to leave a lasting technical legacy and work in a team that values innovation, this is the project for you.

What You’ll Do

• Define and own the modernization strategy for a legacy .NET application, covering backend, frontend, and cloud architecture
• Design modern solutions based on .NET 6–10, Azure services, monolith decomposition, and event-driven approaches
• Lead the transition from WebForms to Blazor, ensuring scalable UI architecture and smooth migration of business logic
• Architect the decomposition of a monolithic application into domain-aligned services, ensuring reliability, observability, and maintainability
• Collaborate with engineering teams to implement cloud-native patterns (API gateways, messaging, containers, distributed caching, resiliency)
• Oversee application hosting modernization using Azure Container Apps, SQL Server Managed Instances, Azure SQL Database, Azure  Landing Zones, Front Door, and App Insights
• Ensure security best practices, authentication/authorization (OAuth2/OIDC), API security, and cloud compliance standards
• Create architecture documentation, diagrams, guidelines, and technical roadmaps
• Mentor senior engineers and guide development teams through modernization phases
• Participate in design reviews, proof-of-concepts, and technical spike initiatives

What You Bring

• 10+ years of experience in software engineering and architecture with strong foundations in .NET and C#
• Proven experience modernizing legacy .NET 4.x / WebForms systems into modern .NET Core/8+ platforms
• Hands-on expertise designing frontends using Blazor, including component architecture, state management, and integration patterns
• Deep knowledge of Azure cloud services
• Strong understanding of microservice architecture, domain-driven design (DDD), event-driven patterns, and distributed systems
• Experience defining migration roadmaps, refactoring strategies, and modernization patterns (strangler fig, side-by-side refactor, lift & shift + optimize)
• Strong background in CI/CD, DevOps collaboration, and architecture considerations related to observability and performance
• Excellent communication skills, ability to work with stakeholders across technical and business domains

Nice to have

• Experience with message-driven platforms (MassTransit, NServiceBus, MediatR)
• Knowledge of frontend modernization strategies (component libraries, UX migration)
• Previous experience in real estate, facility management, or enterprise asset management domains
• Experience performing architectural assessments, audits, or modernization consulting
