Library Software Engineer - Rust

Requirements:

• You have professional experience writing and deploying Rust code in production.
• You have significant experience building and maintaining native libraries (C/C++/Rust) that interoperate with other languages.
• You’re attentive to details and can build software with very low defect rates. You appreciate simplicity as a tool to accomplish this.
• Hands-on experience in software design and leading refactoring initiatives to improve the architecture of complex software libraries.

• Contribute to building a vibrant Rust community within Datadog.
