Knowledge of asymmetric cryptography and architecture/design principles is essential. You should be comfortable with AI tools (Claude, Codex, ChatGPT) and thrive in dynamic, fast-paced environments.
Preferred qualifications include C/C++ library development, PostgreSQL experience, system-level services, OS API interaction (serial ports, block devices), and binary serialization protocols. Bonus skills include robotics software development and WPF/XAML with MVVM patterns.
