Core Infrastructure Engineer 2

About the Role

As a Software Engineer on the Virtual Networking Gateways team, you will design, build, maintain, and test automation for provisioning, deploying, managing, and operating OCI virtual networking fleets. You will participate directly in fleet operations and change management.

Key Responsibilities

• Design, build, maintain, and test automation for provisioning, deploying, managing, and operating OCI virtual networking fleets.
• Participate directly in fleet operations and change management.
• Work primarily in Terraform and Python, contributing to deployment pipelines.
• Improve reliability by writing unit, integration, and end-to-end tests.
• Create and maintain operational runbooks.
• Manage assigned work, maintain clear status in the team’s work-tracking system, and triage overlapping requests from partner service teams.
• Assess requests in the context of fleet scale, available capacity, operational risk, and cost.
• Recognize when a request is disproportionate to the existing environment.
• Engage partner teams directly to clarify requirements and develop feasible approaches, escalating when appropriate.
• 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 operational issues.
• Participate in operational support rotations, assisting in incident responses and root cause investigations.
• 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.
• 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.
• 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.
• 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.
• 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.
• 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.
• Implement updates to processes, protocols, and workflows to increase efficiency and effectiveness as directed, with some guidance.
• Contribute to ideation for future process improvements.
