Software Engineer - Traffic Efficiency
Meta, Menlo Park, California
What you will do
Set technical direction and lead multi-team programs that improve performance, capacity, efficiency, or reliability Diagnose interactions across services, operating systems, network I/O, NICs, CPU and memory, and server platforms using profiling, tracing, telemetry, counters, and controlled experiments Prioritize the highest-leverage opportunities and implement at the right layer, contributing hands-on across layers and partnering where specialized ownership is required Build representative benchmarks and ship changes with monitoring, validation, staged rollout, rollback, and clear ownership Quantify impact and design trade-offs to influence teams outside the engineer's direct ownership Turn regressions and incidents into systemic prevention, reusable methods, and stronger team capability
