Requirements
• Knowledge of C and how programs work:
• Ability to manage memory manually and take care of its initialization
• Knowledge of hardware-dependent concepts: pointers, data layout, stack, bit fields, little/big endian
• Basic data structures
• An idea about registers and machine languages in general
• Some information about weak object symbols, program sections, and linker scripts
• Software development cycle:
• Using the git version control system
• Understanding of toolchains and cross-compilation
• Dealing with heterogeneous build systems (GNU Make, Kconfig, etc.)
• Non-interactive debugging (prints, logs, dump analysis)
• Working with codebases of thousands of files written by hundreds of authors (grepping, ctags, digging in commit history to compensate for the deficiency of documentation)
Nice to have
• Experience with bare-metal programming and hardware abstraction layers
• Experience with (long-running) open-source projects, their mailing lists, and review tools
• Debugging with GDB (remote targets, symbol files, hardware breakpoints)

Ability to manage memory manually and take care of its initialization
Oczekuje się od kandydata umiejętności ręcznego zarządzania pamięcią, co jest typowe dla programowania niskopoziomowego i systemowego, gdzie błędy mogą prowadzić do poważnych problemów.
🟡
An idea about registers and machine languages in general
Wymagane jest podstawowe zrozumienie działania procesora na poziomie sprzętowym, co może sugerować potrzebę głębszego wchodzenia w szczegóły implementacji.
🔴
Working with codebases of thousands of files written by hundreds of authors (grepping, ctags, digging in commit history to compensate for the deficiency of documentation)
Oznacza to pracę z bardzo dużym i potencjalnie chaotycznym kodem, gdzie brak dokumentacji jest normą i trzeba polegać na metodach śledczych.
🟡
Dealing with heterogeneous build systems (GNU Make, Kconfig, etc.)
Kandydat musi być gotowy na pracę z różnorodnymi i potencjalnie skomplikowanymi systemami budowania oprogramowania.
🔴
Non-interactive debugging (prints, logs, dump analysis)
Sugestia, że tradycyjne debuggery interaktywne mogą być niedostępne lub trudne w użyciu, co wymaga umiejętności analizy danych wyjściowych i zrzutów pamięci.
