We are looking for a Senior Architect to help modernize a large, long-standing desktop product built on Microsoft
technologies. The system has evolved over many years and now needs architectural simplification, performance
improvements, and modernization to support future growth. This is a hands-on, core engineering architect role
Key Responsibilities
Study an existing complex desktop application architecture and identify performance and scalability
bottlenecks.
Redesign and modernize core business logic, workflows, and system layers.
Drive migration from legacy .NET Framework to .NET Core, handling real-world dependency and
compatibility challenges.
Redesign inter-component communication (e.g., replacing legacy remoting with contemporary approaches).
Produce a working architectural model within a short timeframe.
Ensure designs meet very strict performance and latency requirements.
Work closely with existing engineering teams and bring a fresh architectural perspective.
Required Experience & Skills
Robust experience as a software / system architect on large, complex products (not just greenfield apps).
Deep hands-on background with Microsoft technologies:
o C#, .NET Framework / .NET Core, COM/DCOM, .NET Remoting
o Experience with legacy components, interop, or mixed-technology systems
Robust understanding of:
o Performance-critical systems
o Low-latency and high-throughput architectures
o Multi-layered desktop or system software
Nice to Have
Experience modernizing legacy systems.
Exposure to C++ or hardware-adjacent software.
Experience working with WPF / MVVM.
Ideal Candidate Profile
Someone who has seen multiple real-world architectures and understands trade-offs.
Comfortable with messy legacy systems and improving them step by step.
Practical, hands-on, and performance-driven.
Experience
12+ years of experience in .NET development
At least 3+ years of recent experience as a Technical Architect in .NET
