Principal Core Infrastructure Engineer

Principal Core Infrastructure Engineer Leads development and begins architecting components of scalable, elastic distributed systems. Defines and enforces scalability requirements for owned components; optimizes code and data paths for highthroughput, hyperscale workloads; and leverages data plane platforms for largescale retrieval, storage, and processing. Designs faulttolerant, inserviceupgradable systems using redundancy, replication, failover, and policies for partitions, applying loadshedding, throttling, and ratelimiting to handle network unreliability while meeting SLOs. Establishes KPIs and telemetry; builds proactive dashboards and alerts; and designs complex validation (fault injection, brownouts), replication, and synchronization for correctness and durability. Proactively diagnoses and resolves production issues, mentors peers, and ensures operational readiness. Implements robust security controls, executes remediation, maintains compliance documentation, and develops IaC and automation that enable safe patching, updates, and rollbacks within changemanagement plans.
