C++ Developer

Overview

We are seeking a highly skilled C++ Engineer to design, develop, and optimize high-performance software applications. The ideal candidate has deep knowledge of C++ (modern standards), software architecture, and performance-critical systems, with experience building reliable and scalable applications.

Key Responsibilities

  • Design, implement, and maintain software components using modern C++ (C++11/14/17/20).

  • Write efficient, high-performance, and maintainable code for complex systems.

  • Collaborate with cross-functional teams (QA, DevOps, Product) to deliver end-to-end solutions.

  • Debug, profile, and optimize code for performance, scalability, and memory usage.

  • Ensure software reliability through testing, code reviews, and documentation.

  • Integrate applications with third-party libraries, frameworks, and APIs.

  • Contribute to software architecture and system design discussions.

  • Maintain knowledge of industry trends, best practices, and emerging C++ standards.

Qualifications

  • Bachelors degree in Computer Science, Engineering, or related field (or equivalent experience).

  • Proven experience as a C++ Software Engineer, Backend Developer, or similar role.

  • Strong proficiency in C++ (C++11 and later), including STL and templates.

  • Solid understanding of object-oriented programming, memory management, and concurrency.

  • Experience with multi-threaded and real-time applications.

  • Knowledge of data structures, algorithms, and system-level programming.

  • Familiarity with build systems (CMake, Make) and version control (Git).

  • Experience with Linux/Unix environments.

Nice-to-Have Skills:

  • Exposure to performance-critical systems (low latency, embedded systems, or high-frequency trading).

  • Knowledge of network programming (TCP/UDP, sockets, gRPC).

  • Familiarity with Python or scripting languages for tooling and automation.

  • Experience with GPU programming (CUDA, OpenCL) or parallel computing.

  • Understanding of databases and distributed systems.
