Director, Core Infrastructure Engineering

** Job Description*
* Leads a multple teams to implement strategies for the architecture and delivery of interdependent, scalable distributed systems that meet organizational and customer demands. Orchestrates cross-group optimization for high‑throughput, large‑scale data processing; aligns stakeholders on scalability requirements; and oversees elastic designs and effective use of data plane platforms. Provides strategic oversight for fault‑tolerant, in‑service‑upgradable architectures, sets direction for partition‑aware design choices, and leads initiatives to harden networks via load‑shedding, throttling, and rate‑limiting.

Establishes expectations for formal verification and peer reviews, and sets SLO‑aligned durability and availability standards across the department. Drives KPI and telemetry strategies; directs creation of complex dashboards and alerting for proactive health assurance; and ensures functional/correctness validation, data replication, and synchronization meet organizational needs. Guides organization‑wide incident management and operational readiness, eliminating customer maintenance windows and ensuring consistent SOPs.

Provides strategic security guidance (encryption, access controls), oversees remediation and compliance documentation, and sponsors automation (IaC) and change‑management alignment so systems can be safely patched, updated, and rolled back at scale.

** Responsibilities*
* ** Key Responsibilities*
* ** System Design & Architecture - System Scalability:*
* + Implements strategies across multiple teams or groups for the architecture and design of interdependent scalable distributed systems, including the use of distributed state management tools, ensuring organizational and system demands are met.

+ Spearheads code and/or system optimization initiatives for large-scale data processing and high-throughput requirements across multiple areas, driving improvements that support hyper-scale systems.

+ Facilitates collaborations to define system scalability requirements, ensuring the defined requirements meet customer expectations.

+ Oversees the design of interdependent systems to scale with elasticity (e.g., effectively scaling both up and down).

+ Drives the effective use and implementation of data plane platforms for large-scale data operations.

** System Design & Architecture - System Reliability Design:*
* + Provides strategic oversight for the architecture of fault-tolerant interdependent systems capable of withstanding in-service updates by overseeing implementation across teams of redundancy, replication, and automatic failover mechanisms.

+ Influences and sets direction for designing systems to effectively handle service disruptions (e.g., network partitions) by prioritizing consistency, availability, or partition tolerance.

+ Leads strategic optimization initiatives for handling network unreliability, including directing the design of load-shedding, throttling, and rate-limiting techniques.

+ Holds teams accountable for leveraging formal verification techniques to verify system designs and conduct peer reviews across teams.

+ Drives the design of systems that are durable and adhere to service level objectives (SLOs), developing standards for availability and durability of other computing services across the department.

** System Design & Architecture - System Reliability Performance:*
* + Drives strategies for defining key performance indicators (KPIs) and telemetry to identify risks, gaps, or cyclical dependencies in running systems, ensuring alignment with organizational goals.

+ Directs the creation and customization of complex dashboards, telemetry systems, and alerting mechanisms that proactively monitor and ensure optimal system health across teams.

** System Design & Architecture - Correctness / Availability:*
* + Implements strategies to effectively determine if systems are meeting functional and correctness requirements, and encourages teams to identify improvement opportunities.

+ Provides thought leadership on processes for formally verifying complex features to ensure system design correctness.

+ Oversees the implementation of data replication and…
