Senior C++ Developer

Accelya is looking for an experienced Senior C++ Developer who enjoys working at a low level, focusing on performance, efficiency, and direct control over system resources. If you thrive in writing code without relying on higher-level libraries and find satisfaction in optimizing every aspect of performance, this role is for you.

In this position, you will work on building efficient, low-overhead software solutions for both Windows and Linux environments, creating custom data structures, algorithms, and memory management solutions.

Key Responsibilities:

• Design, develop, and optimize low-level C++ code, focusing on performance and efficiency with minimal reliance on higher-level abstractions.
• Write custom data structures and algorithms tailored to system needs, ensuring high performance and low resource usage.
• Handle manual memory management, optimize CPU cycles, and implement custom allocators and memory pools for performance-critical applications.
• Troubleshoot and debug complex performance issues, memory leaks, and low-level system bugs using tools such as GDB and WinDbg.
• Maintain a strong focus on writing clean, maintainable code while ensuring high performance and stability across both Windows and Linux platforms.
• Write and execute unit tests to validate system-level software, ensuring high standards of reliability and performance.

Required Skills and Experience:

• Hands-on experience in C++ programming, with a focus on low-level, system-level, and performance-critical applications.
• Solid experience with manual memory management, including custom allocators, raw pointers, and low-level resource management.
• Strong knowledge of multi-threading, synchronization, and concurrency in C++, using primitives such as atomic operations, spinlocks, and mutexes.
• Expertise in systems programming and understanding of OS internals on both Windows and Linux (kernel, memory management, file systems, etc.).
• Ability to optimize software for both CPU cycles and memory usage, ensuring high efficiency and minimal resource consumption.
• Proficient in debugging and profiling tools.
• Extensive experience with CMake, Visual Studio, GCC, or other build and development tools on both Windows and Linux platforms.
• Experience with unit testing frameworks such as Google Test.
• Strong understanding of system architecture, including hardware-software interaction, CPU, memory, and I/O.
• Experience working in containerized environments.
