Windows Software Developer – Performance Diagnostic Toolsets

At Quest Global, it’s not just what we do but how and why we do it that makes us different. With over 25 years as an engineering services provider, we believe in the power of doing things differently to make the impossible possible. Our people are driven by the desire to make the world a better place—to make a positive difference that contributes to a brighter future. We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster.

Key Responsibilities

1. Develop and maintain Windows-based diagnostic toolsets to analyze and visualize system performance across different hardware configurations.
2. Focus on UI/UX design to ensure tools are intuitive and user-friendly, enabling seamless navigation and interaction for developers and engineers.
3. Integrate power measurement APIs to track and display real-time system power consumption, CPU/GPU/other resource usage, and other performance metrics.
4. Implement data visualization techniques, transforming raw data into easily understandable graphs, charts, and tables to highlight performance bottlenecks.
5. Work closely with system performance teams to identify key metrics and integrate those into the diagnostic toolset for comprehensive monitoring.
6. Ensure scalability and performance of diagnostic tools across different system environments, from basic desktop machines to high-end computing setups.
7. Write clean, efficient, and well-documented code using modern Windows development technologies and practices (e.g., C++, .NET, Win32 APIs).
8. Troubleshoot and resolve bugs or performance issues in diagnostic tools, ensuring they provide accurate insights into system health and performance.
