You think at scale, connecting your work to the larger company mission and building solutions that support a high-growth, global organization.

What We’re Looking for (Minimum Qualifications)

Extensive experience coding with Rust, particularly in systems programming and async frameworks like Tokio or async-std
Proven expertise in building resilient, observable, and horizontally scalable distributed systems
Strong understanding of Linux fundamentals, including networking, namespaces, sockets, and kernel-user space interaction
Proficiency in container-based environments, Git, CI/CD workflows, and performance instrumentation

What Will Make You Stand Out (Preferred Qualifications)

Proven ability to leverage AI technologies and workflows to drive measurable operational efficiency
Experience with systems languages like C/C++ or Go, particularly in performance-critical environments
