Core Infrastructure Engineer 2

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.
