Principal Core Infrastructure Engineer
Senior Distributed Systems Architect (IC4)
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 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, 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 that enable safe patching, updates, and rollbacks within change-management plans.
Responsibilities
System Design & Architecture
System Scalability
- Lead the development and implementation, and begin to architect scalable distributed systems that support horizontal and vertical scaling to meet system demands, leveraging distributed state management tools.
- Optimize code and system performance for large-scale data processing and high-throughput requirements for hyper-scale systems.
- Define scalability requirements for owned components and ensure design and implementation requirements are met.
- Design systems to scale elastically (e.g., effective scaling up and down under demand).
- Leverage data plane platforms to enhance large-scale retrieval, storage, and processing.
- Design performance and load testing frameworks for validation before deployment.
System Reliability Design
- Build fault-tolerant components and systems capable of in-service updates, using redundancy, replication, and automatic failover.
- Design systems to handle service disruptions (e.g., network partitions) while prioritizing consistency, availability, or partition tolerance (CAP theorem).
- Implement and optimize load-shedding, throttling, and rate-limiting for resilience against network unreliability.
- Ensure components and systems adhere to Service Level Objectives (SLOs), setting clear availability and durability expectations across teams.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
System Reliability Performance
- Define and monitor key performance indicators (KPIs) and telemetry to identify system gaps.
- Build and customize dashboards, telemetry systems, and alerting mechanisms to proactively track component and system health.
Correctness & Availability
- Design and implement functional requirements for feature sets in new or existing systems.
- Develop complex test scenarios (e.g., fault injection, brownouts) to validate system correctness.
- Implement data replication and synchronization to ensure data integrity and high availability.
Operational Troubleshooting & Incident Management
- Proactively diagnose, debug, and resolve active production issues, ensuring ongoing system stability.
- Implement no-downtime troubleshooting to prevent disruptions during customer-facing operations.
- Maintain deep expertise in owned components to support efficient incident resolution.
- Operational readiness: Contribute to design and implementation ensuring readiness before deployment.
- Serve in rotational operational support, guiding incident response and performing root cause analysis.
Compliance & Security
- Implement robust security controls (e.g., encryption, access management) for multi-tenant environments.
- Execute remediation plans for security vulnerabilities and exploited gaps.
- Ensure cloud infrastructure compliance with industry standards and regulations, maintaining up-to-date documentation.
Automation & Change Management
- Develop and maintain automation scripts and tools (IaC, scripting) for cloud infrastructure management.
- Create and adhere to change management plans for patching, updating, and rolling back applications.
- Begin designing systems/tooling to enable automated patching, updates, and rollbacks.
Core Responsibilities
Planning & Execution
- Manage and coordinate complex tasks in moderately-sized projects or initiatives, monitoring timelines and deliverables to ensure adherence.
- Efficiently delegate, monitor, and prioritize work across multiple projects, providing technical oversight and adjusting strategies for resource constraints.
