Principal Core Infrastructure Engineer
Senior Distributed Systems Engineer (IC4)
Leads development and begins architecting components of scalable, elastic distributed systems. Defines and enforces scalability requirements, optimizes code and data paths for high-throughput, hyper-scale workloads, and leverages data plane platforms for large-scale retrieval, storage, and processing. Designs fault-tolerant, in-service-upgradable systems using redundancy, replication, failover, and policies for partitions, while applying load-shedding, throttling, and rate-limiting 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 Infrastructure as Code (IaC) and automation to enable safe patching, updates, and rollbacks within change-management plans.
Responsibilities
System Design & Architecture
System Scalability
- Lead development, implementation, and early architecture of scalable distributed systems supporting horizontal/vertical scaling (e.g., distributed state management tools).
- Optimize code/data paths for high-throughput, hyper-scale workloads.
- Define and enforce scalability requirements for owned components.
- Design elastic systems (e.g., auto-scaling up/down).
- Leverage data plane platforms for large-scale data retrieval, storage, and processing.
- Design and execute performance/load testing.
