Core Infrastructure Engineer

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. Key Responsibilities System Design & Architecture - System Scalability: –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. System Design & Architecture - System Reliability Design: –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 System Design & Architecture - System Reliability Performance: –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. System Design & Architecture - Correctness / Availability: –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. Operational Troubleshooting & Incident Management: –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 operational issues. –Participate in operational support rotations, assisting in incident responses and root cause investigations. Compliance & Security: –Assist in implementing basic security measures to protect data and applications in multi-tenant environments, including encryption and access controls. –Assist in the execution of remediation plans to address identified security gaps, under supervision. –Support the creation and updating of documentation to ensure cloud infrastructure is in compliance with relevant industry standards and regulations. Automation & Change Management: –Assist in maintaining basic automation scripts and tools (e.g., Infrastructure as Code (IaC)). –Adhere to change management plans for patching, updating, and rolling back applications, under guidance Core Responsibilities Planning & Execution: –Track timelines with minimal supervision, ensuring work is completed in a timely manner and is in alignment with project requirements. –Prioritize and adjust work as resources or timelines change, with some guidance Collaboration & Partnership: –Collaborate within the team to better understand expectations and achieve shared objectives. –Leverage a foundational understanding of business, stakeholder, and/or customer needs to build partnerships with limited guidance. –Actively listen and ask questions to enhance collaboration. –Build a basic understanding of business, stakeholder, and/or customer needs with guidance. Problem Solving: –Identify and address issues, escalating problems to senior staff as needed in accordance with standard procedures. –Compile and review data and/or information from multiple sources to troubleshoot standard and non-standard errors. Continuous Learning: –Seek opportunities to gain knowledge and learn new skills and/or tools aligned with industry trends and best practices. –Utilize feedback and training to improve skills. –Participate in a culture of continuous learning and knowledge sharing. Continuous Improvement: –Implement updates to processes, protocols, and workflows to increase efficiency and effectiveness as directed, with some guidance. –Contribute to ideation for future process improvements.
