Manages team delivering scalable distributed systems and components on a 2–4 quarter horizon. Standardizes engineering practices and scalability requirements across teams; oversees optimization for high‑throughput, hyper‑scale workloads; and ensures effective use of distributed state tools and data plane platforms. Guides teams to design fault‑tolerant, in‑service‑upgradable systems, set SLO‑aligned durability/availability targets, and implement resiliency mechanisms (load‑shedding, throttling, rate‑limiting). Provides oversight for KPIs, telemetry, and moderately complex dashboards; directs design of functional/correctness requirements, fault‑injection tests, and replication/synchronization strategies. Ensures proactive incident management, operational readiness, and on‑call coverage; drives encryption/access control practices, remediation plans, and compliance documentation. Oversees development and maintenance of automation/IaC and partners with teams on change‑management plans enabling safe patching, updates, and rollbacks.
