Senior C++ Developer

Job Description

Position Overview

We are seeking an experienced Windows C++ Senior Software Engineer with strong, hands-on expertise in Win32 and MFC. This role is focused on enhancing and maintaining a complex legacy desktop application built heavily on MFC. The ideal candidate is someone who has deep exposure to large, intricate Windows codebases—not simply general-purpose or historical C++ experience.

This is a high-visibility role requiring direct customer engagement and the ability to deliver confidently without a learning curve on Win32/MFC fundamentals.

Key Responsibilities

• Enhance, maintain, and modernize a complex, legacy MFC-based Windows desktop application.
• Work through tightly coupled UI logic, large view hierarchies, and challenging architectural areas in an existing MFC codebase.
• Collaborate closely with customers, providing technical credibility and professional communication in a visible engagement.
• Serve as a primary strong C++ engineer within the project team.
• Work across the Windows desktop stack, ensuring seamless integration within the existing Win32/MFC architecture.
• Ensure high reliability, stability, and maintainability of the application with minimal oversight.
• Contribute to reducing technical risk by bringing proven, demonstrable Windows C++ expertise.

Qualifications

Required Skills & Experience

• 7 to 10 Years of strong, recent, and hands-on experience in Windows-native C++ development, specifically with Win32 API and MFC (not general or outdated C++ work).
• Experience modernizing legacy Windows applications.
• Beneficial would be experience working on computational science and computational solvers. Experience in optimisation, parallelisation, multithreading, mathematical models, complex data models. Familiarity with COM Windows debugging tools, or Visual Studio diagnostics.
• Understanding performance optimization in MFC/Win32.
• Ability to navigate and refactor large legacy codebases.
• Proven experience maintaining or improving complex legacy MFC applications, including areas with poor coding practices or deep UI coupling.
• Ability to be productive immediately, without ramp-up time on Win32/MFC fundamentals.
• Strong problem-solving capabilities within Windows desktop environments.
• Comfort working directly with customers—professional communication, credibility, and clarity are essential.
• Demonstrated history of delivering high-quality software with low risk of escalation due to skill gaps.
