When recruiting a Rust developer, a thorough understanding of the language and its standard library is crucial. The candidate should demonstrate skills in writing efficient, secure code and applying Rust features such as ownership, borrowing, and lifetimes.

It is important that the Rust developer has experience in system programming. Familiarity with issues such as memory management, concurrency and system interfaces is important, as Rust is often used in systems with high performance and security requirements.

The candidate should be proficient in the use of Cargo and Crates.io and familiar with other Rust ecosystem tools that support the build, test and dependency management process. Familiarity with development environments and debuggers that support Rust is also important.

A Rust developer should have experience integrating Rust with other programming languages such as C, C++ or Python, which is often required for projects using existing libraries or systems. Familiarity with FFI (Foreign Function Interface) is essential here.

It is important that a Rust developer has experience developing applications that run on different operating systems, such as Linux, Windows, and macOS. The ability to ensure compatibility and optimisation for different platforms is valued in wide-ranging projects.

Communication skills and the ability to work in a team are key, as Rust projects often require collaboration with other developers, engineers and analysts. The candidate should collaborate effectively and communicate progress and technical issues.
