Core Infrastructure Engineer

Job Description

Implements and optimizes components within existing distributed systems under guidance. Applies basic scalability requirements, conducts performance/load testing, and configures resiliency features (retries, circuit breakers, timeouts) to handle network variability. Builds telemetry, alerts, and runbook-driven procedures; delivers scoped features and fault-injection tests; and helps implement basic data replication and synchronization. Assists with on-call rotations, uses automation/IaC scripts to troubleshoot, and follows change, security, and compliance procedures (encryption, access controls, remediation plans) while escalating complex issues to senior engineers.

• –Assist in the implementation of components of distributed systems that support horizontal and vertical scaling under the guidance of senior engineers.
• –Optimize code segments and/or systems for large-scale data processing with oversight from senior engineers.
• –Implement scalability requirements for assigned components.
• –Learn about the use of data plane platforms for large-scale data retrieval, storage, and processing.
• –Execute performance and load testing, with guidance.

• –Collaborate with the team to build fault-tolerant components capable of withstanding in-service updates by learning about redundancy, replication, and automatic failover mechanisms.
• –Learn about recovery oriented computing principles and assist in applying them to component designs.
• –Configure and test retry mechanisms, circuit breakers, and timeouts to help handle network unreliability, with guidance

• –Implement testing and alarming configurations to detect issues/failures.
• –Support efforts to recover from failures by drafting and executing runbooks and operational procedures, under guidance.
• –Help build dashboards, telemetry systems, and alerting mechanisms to monitor component health.

• –Implement functional requirements and testing for assigned features within an existing system.
• –Implement test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness, under guidance.
• –Help implement basic data replication and synchronization techniques to maintain data integrity and availability.

• –Assist in diagnosing and debugging issues in system components to support ongoing operation, under supervision.
• –Follow protocols to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues.
• –Run basic automation scripts and tooling to troubleshoot
