• Develop and maintain Modern C++ software supporting high-speed PCIe and Ethernet data streaming (100–400 Gbps).
• Perform system-level integration, testing, and validation of hardware and software components.
• Debug and troubleshoot issues across the stack, including device registers, drivers, and application software.
• Collaborate with cross-functional engineering teams to ensure reliable system integration and operation.

🧠Required Qualifications

• Bachelor’s or master’s degree in computer engineering, Electrical Engineering, Computer Science, or a related field.
• Strong experience with Modern C++ and object-oriented software design.
• Experience developing or integrating hardware control software.
• Solid understanding of modern I/O architectures, particularly PCIe and high-speed Ethernet systems.
• Experience debugging across hardware, drivers, and application layers.
• Development experience in Linux and/or Windows environments.
• English level: B2+

🌟Preferred Qualifications

• Strong experience debugging complex, multi-layer system issues.
• Experience with multithreaded and high-performance software design.
• Familiarity with instrument control systems or electronic test and measurement environments.
• Experience with cross-platform development (Windows, Linux, Embedded Linux).
• Knowledge of Python, C#, or other supporting languages.
• Experience with test automation, CI/CD pipelines, or DevOps workflows.
• Strong analytical and problem-solving skills and ability to collaborate in distributed engineering teams.
