You have deep systems-level experience with Linux, the kind that comes from debugging cryptic kernel errors at 2 AM and knowing which mailing list thread to dig up or which snippets of code in the kernel’s source tree to dig into. You’ll be living close to the kernel, pushing Rust’s concurrency model to its limits, and solving problems that don’t have StackOverflow answers and make even ChatGPT throw its hands up in the air and say “idk.” .
