Principal Core Infrastructure Engineer

About the Role

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.

Responsibilities

• System Design & Architecture - System Scalability:
  • Lead the development and implementation, and begin to architect, components of scalable distributed systems that support horizontal and vertical scaling to meet system demands, including leveraging distributed state management tools.
  • Optimize code and/or systems for large-scale data processing and high-throughput requirements to support hyper-scale systems.
  • Define scalability requirements for owned components and ensure design and implementation requirements are met.
  • Design systems to scale with elasticity (e.g., effectively scaling both up and down).
  • Leverage data plane platforms to effectively handle large-scale data retrieval, storage, and processing.
  • Design performance and load testing.
• System Design & Architecture - System Reliability Design:
  • Build and design fault-tolerant components and systems capable of withstanding in-service updates by implementing redundancy, replication, and automatic failover mechanisms.
  • Design systems to effectively handle service disruptions (e.g., network partitions) by prioritizing consistency, availability, or partition tolerance.
  • Implement and optimize approaches to handle network unreliability, including load-shedding, throttling, and rate-limiting.
  • Design components and systems that are durable and adhere to service level objectives (SLOs), setting expectations for availability and durability of other computing services within the department.
• System Design & Architecture - System Reliability Performance:
  • Define key performance indicators (KPIs) and telemetry to identify gaps or issues in running systems.
  • Build and customize moderately complex dashboards, telemetry systems, and alerting mechanisms to proactively monitor components and system health.
• System Design & Architecture - Correctness / Availability:
  • Design and implement functional and correctness requirements for feature sets and/or systems in new or existing systems.
  • Design complex test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness.
  • Implement data replication and synchronization techniques to maintain data integrity and availability.
• Operational Troubleshooting & Incident Management:
  • Take a proactive role in diagnosing, debugging, and resolving issues in active components and systems to support ongoing operation, and mentor others in these processes.
  • Implement strategies to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues.
  • Maintain expertise in owned components and systems to ensure effective troubleshooting and performance.
  • Meet operational readiness expectations through design and implementation.
  • Serve in operational support rotations, providing guidance in incident response and root cause investigations.
• Compliance & Security:
  • Implement robust security measures to protect data and applications in multi-tenant environments, including encryption techniques and access controls.
  • Execute remediation plans to address identified security gaps.
  • Ensure cloud infrastructure is in compliance with industry standards and regulations and that documentation is up to date.
• Automation & Change Management:
  • Develop and maintain automation scripts and tools (e.g., Infrastructure as Code (IaC)) to manage cloud infrastructure.
  • Create and adhere to change management plans for patching, updating, and rolling back applications, and begin designing systems and components to allow for automation of these processes.
• Planning & Execution:
  • Manage and coordinate moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative.
  • Efficiently delegate, monitor, and prioritize work across multiple projects, providing technical oversight and adjusting plans to address shifts in resources or timelines.
• Collaboration & Partnership:
  • Collaborate across the organization to align on expectations and achieve shared objectives.
  • Leverage understanding of business leaders, stakeholders, and/or customers to ensure proposed solutions meet their needs.
  • Support inclusivity by actively seeking and listening to diverse perspectives, ensuring others feel heard and respected.
• Problem Solving:
  • Identify and address moderately complex issues by analyzing a wide range of data and/or information to identify solutions in accordance with standard practices.
  • Proactively escalate unresolved or critical issues with a thorough assessment and suggest potential solutions.
  • Review, contribute to, and document problem-solving strategies.
• Continuous Learning:
  • Pursue learning opportunities to expand knowledge and skills and/or tools in new areas and stay abreast of the latest industry trends and best practices.
  • Proactively seek and leverage ongoing feedback and training to improve skills.
  • Coach and mentor junior team members, fostering continuous learning and knowledge sharing within and across teams.
• Continuous Improvement:
  • Develop ideas, recommend updates, and/or collaborate on the implementation of process improvements to increase the efficiency and effectiveness of processes, protocols, and workflows across teams, and evaluate the impact on key stakeholders.
  • Solicit feedback from others on ideas for alternative approaches and methods for continued improvement.
• Performance and Development:
  • Contribute to the talent development pipeline by participating in candidate interviews, assessing candidates, and providing hiring recommendations.
