Core Infrastructure Engineer 2

Job description

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. 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.
