At Staffy, we are looking for a C++ Developer to join the core engineering team behind a high-performance trading platform operating in demanding fintech environments.
This role is focused on the evolution and modernization of a mission-critical platform handling real-time APIs, low-latency execution, and extremely high transaction volumes. The environment requires strong systems-level thinking, deep understanding of performance optimization, and the ability to work on resilient, highly available architectures where stability and efficiency are critical.

Contribute to the migration of 40+ legacy MFC dialogs into modernized UI components.
Analyze and optimize memory utilization, concurrency, resiliency, and runtime performance.
Ensure high availability, fault tolerance, and operational stability across critical platform services.
Collaborate with engineering teams to improve scalability, performance, and platform reliability.
Perform AI-assisted development workflows, ensuring code quality and architectural consistency.
Participate in architectural discussions, technical reviews, and performance optimization initiatives.
Troubleshoot complex production issues in latency-sensitive environments.
Work within highly secure environments where source code and systems cannot rely on public cloud infrastructure.
