Sr Software Engineer, Core Infrastructure

As a Senior Core Infrastructure Engineer, you will design and develop major new features within existing systems, playing a key role in driving engineering excellence. You'll help elevate development practices, operational efficiency, team ownership, and mentoring culture. You may also collaborate with teams across the organization. You will write secure, maintainable, and robust code along with comprehensive tests. You'll lead the design and implementation of features and subsystems, ensuring their operational readiness and excellence.

You will actively participate in planning and risk mitigation for systems and services across the organization. You'll work independently on most projects, occasionally requiring guidance in areas that demand deep industry experience - such as designing secure, high-performance, scalable systems or managing complex cross-team dependencies. You'll frequently identify and resolve issues without needing assistance, lead root cause analysis efforts, and recommend effective solutions.

You'll also build new metrics and dashboards to enhance visibility and situational awareness. Additionally, you'll identify and implement improvements that reduce operational overhead, increase availability, improve compliance with organizational standards, and minimize technical debt.

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.

• 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
• Collaborates across teams to align on expectations and achieve shared…
