Key Responsibilities

• Analyze and understand a large, complex legacy C++ codebase.
• Troubleshoot and resolve deep system-level issues such as memory leaks, heap/stack corruption, race conditions, and performance bottlenecks.
• Lead modernization efforts including code refactoring, partial rewrites, and design improvements, using static code analysis, AI-assisted tools, and manual reviews.
• Drive architectural evolution towards a stateless microservices-based architecture.
• Collaborate with stakeholders to define technical strategy and roadmap alignment.
• Design and implement high-performance, scalable, and maintainable components in C++.
• Perform rigorous performance testing, benchmarking, and tuning across bare metal, virtualized, and containerized environments.
• Ensure code quality and reliability through best practices and tool usage (valgrind, ASan/TSan, perf, gdb, etc.).
• Provide mentorship and technical guidance to development teams.
• Collaborate cross-functionally with QA, DevOps, and Product Management.

Required Skills and Experience

• Expert-level proficiency in C++

  (including modern standards up to C++17/20), STL, and low-level system programming.
