• Partner with performance teams on scaling, resilience, and low-latency infra work


• Own foundational systems end-to-end and keep them simple, reliable, and easy to operate

Required Qualifications

• 5+ years of experience operating large-scale infrastructure


• Strong programming skills and familiarity with modern infra tooling


• Understanding of hardware, operating systems, and networking
