About The Position

The Senior Core Infrastructure Engineer designs, implements, and optimizes distributed-system components, emphasizing scalability, resiliency, and operability. The role delivers features and load/performance tests; uses data-plane platforms and distributed-state tools for high-volume retrieval, storage, and processing; and reviews implementations for scalability compliance. The engineer builds fault-tolerant systems using redundancy, replication, and automatic failover; applies recovery-oriented design principles; and implements retries, circuit breakers, and timeouts. The role proactively detects and mitigates issues through tests, alarms, dashboards, and telemetry; authors runbooks; and participates in incident response and root-cause investigations. It also covers data replication and synchronization, operational automation and Infrastructure as Code, advanced security controls, and adherence to change-management, compliance, and documentation standards.

Responsibilities

Implement and contribute to distributed-system components that support horizontal and vertical scaling, including use of distributed-state management tools.
Optimize code and systems for large-scale data processing and use data-plane platform components for large-scale data retrieval, storage, and processing.
Implement scalability requirements for assigned components and review team members’ implementations.
Implement performance and load testing.
Collaborate on fault-tolerant components that withstand in-service updates through redundancy, replication, and automatic failover.
Apply recovery-oriented computing principles and implement retries, circuit breakers, and timeouts to handle service disruptions and network unreliability.
Implement tests and alarm configurations to proactively detect and address issues or failures.
Draft and execute runbooks and operational procedures to support recovery from failures.
Build and customize dashboards, telemetry, and alerting to monitor component health.
Design and implement feature requirements and tests, including fault-injection and brown-out scenarios, and implement data replication and synchronization to maintain integrity and availability.
Diagnose, debug, and resolve component issues; implement strategies to avoid customer maintenance windows; and develop troubleshooting automation and tools.
Participate in operational support rotations, incident response, and root-cause investigations.
Apply advanced security measures, including encryption and access controls, implement security remediation plans, and help ensure cloud infrastructure complies with applicable standards and regulations with current documentation.
Maintain automation scripts and tools, including Infrastructure as Code, and follow change-management plans for patching, updates, and rollbacks.
Track timelines, complete work in alignment with project requirements, and adjust priorities as resources or timelines change.
Collaborate across teams, align expectations, and build understanding of stakeholder and customer needs.
Identify and address standard and non-standard issues, analyze information from multiple sources, escalate complex issues as appropriate, and contribute to knowledge sharing.
Build skills and stay current with industry trends and best practices; use feedback and training to improve.
Recommend process, protocol, and workflow improvements, seeking input on alternative approaches.
