Senior Core Infrastructure Engineer

About the role

Designs, implements, and optimizes components in distributed systems with an emphasis on scalability, resiliency, and operability. Delivers features and load/performance tests; leverages data plane platforms and distributed state tools for high-volume retrieval, storage, and processing; and reviews peers’ implementations for scalability compliance. Builds fault-tolerant paths (redundancy, replication, automatic failover), applies recovery-oriented principles, and implements retries, circuit breakers, and timeouts. Proactively detects and mitigates issues via tests, alarms, dashboards, and telemetry; authors runbooks and participates in incident response and RCAs. Implements standard replication and synchronization, develops automation/IaC for troubleshooting and maintenance, and applies advanced security controls (encryption, access, remediation) while ensuring change, compliance, and documentation standards are met.

  • Designs and implements functional requirements and testing for assigned features within an existing system.
  • Implements test scenarios (e.g., fault-injection, brown-out) to evaluate system correctness.
  • Implements standard data replication and synchronization techniques to maintain data integrity and availability.
• Operational Troubleshooting & Incident Management
  • Diagnoses, debugs, and resolves issues in system components to support ongoing operation.
  • Implements basic strategies to prevent interruptions, ensuring no maintenance windows are required for customers and users when resolving issues.
  • Designs and implements automation scripts and tooling used to troubleshoot operational issues.
  • Participates in operational support rotations, assisting in incident responses and root cause investigations.
• Compliance & Security
  • Applies advanced security measures to protect data and applications in multi-tenant environments, including encryption and access controls.
  • Implements remediation plans to continuously improve security.
  • Collaborates with the team to ensure cloud infrastructure complies with relevant industry standards and regulations and that documentation is up-to-date.
• Automation & Change Management
  • Maintains automation scripts and tools (e.g., Infrastructure as Code (IaC)) for managing cloud infrastructure.
  • Adheres to change management plans for patching, updating, and rolling back applications.
• Core Responsibilities
  • Planning & Execution: Tracks timelines with minimal supervision, ensuring work is completed in a timely manner and is in alignment with project requirements. Prioritizes and adjusts work as resources or timelines change, with some guidance.
  • Collaboration & Partnership: Collaborates across teams to align on expectations and achieve shared objectives. Builds and maintains a comprehensive understanding of business, stakeholder, and/or customer needs to build and support effective partnerships. Actively listens to diverse perspectives and asks questions to ensure understanding of others.
  • Problem Solving: Independently identifies and addresses standard and non-standard issues in accordance with standard practices, escalating more complex issues as appropriate. Analyzes data and/or information from multiple sources to troubleshoot standard and non-standard errors. Contributes to knowledge sharing and best practices.
  • Continuous Learning: Embraces continuous learning by actively seeking to build knowledge and new skills and/or tools, and staying current with industry trends and best practices. Seeks out and leverages feedback and training to improve skills. Contributes to a culture of continuous learning and knowledge sharing with team members.
  • Continuous Improvement: Develops ideas and recommends updates to increase the efficiency and effectiveness of processes, protocols, and workflows within a team. Seeks input from team members on alternative approaches and methods for improving work.
