About the Role
We are looking for a hands-on .NET Solutions Architect to lead the modernization of a large-scale enterprise platform.
This role focuses on reverse engineering legacy systems, uncovering hidden business logic, and designing scalable, cloud-ready architectures that will define the platform's future.
You will play a critical role in evaluating the existing system, defining target architecture, and ensuring a scalable, secure, and future-ready solution aligned with business goals.
Key Responsibilities
- Analyze and assess the existing .NET application (architecture, codebase, dependencies, and data flows)
- Define and own the modernization roadmap from current .NET to the latest .NET (Core / .NET 8+) stack
- Design and implement a microservices-based architecture using modern design patterns
- Lead the migration to AWS Cloud, defining cloud-native architectures and best practices
- Establish standards for API design, service communication, security, and observability
- Guide teams on strangler, re-platforming, and re-engineering strategies
- Work closely with product owners, business stakeholders, and engineering teams
- Review and approve architecture designs, code standards, and technical implementations
- Ensure scalability, performance, resiliency, and cost optimization in the target architecture
- Mentor senior and mid-level engineers on cloud and microservices best practices
- Drive governance, risk mitigation, and technical decision-making across the program
