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.

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.
• Contributes to knowledge sharing and best practices

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
• 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 feedbac
