Strong programming skills in C/C++ for embedded systems, with experience in assembly language as a plus.

Experience with communication protocols (I2C, SPI, UART, CAN, USB, Ethernet, etc.) and real‑time system constraints.

Familiarity with debugging tools (JTAG, SWD, oscilloscopes, logic analyzers) and embedded development environments.

Experience developing C++ applications for embedded systems.

Proficiency in CI/CD workflow development for embedded firmware projects (e.g., Teamcity, GitLab CI, or similar).
