Qualifications

• At least 6 years of experience building and operating large-scale networking or infrastructure systems.

• Investigate complex networking issues across the stack, from the kernel and data plane to distributed systems and edge networking.
• Drive performance and reliability improvements through systematic profiling and tuning.
• Partner with engineers across the company to build a platform that is stable, predictable, and secure.
