Summary
👤
Senior🎓
Top SchoolRahul Iyengar is a Production Engineer with 13 years of experience building and operating large-scale infrastructure, currently driving reliability at Meta from Seattle. Over seven years at Meta he’s led incident response, redesigned core RPC region selection to cut tail latency, and built investigation and low-level mitigation tooling that materially reduced response time. He combines hands-on systems work—from managing production web server fleets to disaster recovery—with team leadership and mentoring across site reliability and CLI tooling initiatives. Earlier roles in network engineering and product-focused software development sharpened his end-to-end perspective on datacenter, networking, and ingest pipelines. An active contributor to high-profile open-source projects like HHVM, he has made pragmatic performance and HTTP resilience improvements that improved stability at scale. Rahul is known for quickly developing deep domain knowledge under time pressure and translating it into sustainable, systemic solutions.
