Job description

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.

Internal Responsibilities

• Key Responsibilities
  • System Design & Architecture - System Scalability:
    • Implements and contributes to the development for components of distributed systems that support horizontal and vertical scaling including leveraging distributed state management tools.
    • Optimizes code and/or systems for large-scale data processing in large-scale systems.
    • Implements scalability requirements for assigned components and reviews implementation of team members.
    • Leverages components of data plane platforms to handle large-scale data retrieval, storage, and processing.
    • Implements performance and load testing.
  • System Design & Architecture - System Reliability Design:
    • Collaborates with team to build fault-tolerant components capable of withstanding in-service updates by implementing redundancy, replication, and automatic failover mechanisms.
    • Applies recovery-oriented computing principles to design components that effectively handle service disruptions.
    • Implements retry mechanisms, circuit breakers, and timeouts to help handle network unreliability.
  • System Design & Architecture - System Reliability Performance:
    • Implements tests and alarm configurations to proactively detect and address issues/failures.
    • Supports efforts to recover from failures by drafting and executing runbooks and operational procedures.
    • Builds and customizes dashboards, telemetry systems, and alerting mechanisms to monitor component health.
  • System Design & Architecture - Correctness / Availability:
    • Designs and implements functional requirements and testing for assigned features within an existing system.
    • Implements tests 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:
    • 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:
    • 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
