Principal Core Infrastructure Engineer - AI Infrastructure
About The Position
The Principal Core Infrastructure Engineer designs, implements, tests, and optimizes components of large-scale distributed systems and data-plane services, with emphasis on scalability, resiliency, availability, and operability. The role builds scalable data-processing systems using distributed state, replication, synchronization, and high-volume retrieval and storage patterns, and strengthens reliability through redundancy, automatic failover, recovery-oriented design, retries, circuit breakers, and timeouts. The engineer develops performance, load, reliability, and fault-injection tests; creates observability and operational tools such as dashboards, alarms, telemetry, runbooks, and automation; and diagnoses production problems while participating in on-call rotations, incident response, and root-cause analysis. The position also develops infrastructure automation and Infrastructure as Code for maintenance and troubleshooting, and applies security controls such as encryption, access controls, and vulnerability remediation in multi-tenant environments. Work must be performed onsite near Nashville, Tennessee; candidates must live nearby or be willing to relocate.
Requirements
- Must live near Nashville, Tennessee, to regularly go into the office, or be willing to relocate for onsite work.
- Bachelor's or master's degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience.
- At least 7 years of professional software-development experience; advanced degree holders may have fewer years of experience.
- Proficiency in at least one object-oriented or systems programming language, such as Java, C++, C#, or Go.
- Experience building or operating scalable, highly available distributed systems or cloud infrastructure.
- Experience with system-level testing and automation, including performance, load, reliability, or fault-injection testing.
- Understanding of distributed-systems concepts, data structures, algorithms, operating systems, networking, and secure software-development practices.
- Strong debugging, problem-solving, communication, and cross-functional collaboration skills.
Nice To Haves
- Experience with cloud platforms such as Oracle Cloud, AWS, Azure, or Google Cloud.
- Experience with data-plane platforms, distributed storage, microservices, state management, replication, or large-scale data processing.
- Experience with observability, incident management, Infrastructure as Code, and production service operations.
- Familiarity with compliance requirements and security controls for cloud infrastructure.
Responsibilities
- Design, implement, test, and optimize components of large-scale distributed systems and data-plane services.
- Build for horizontal and vertical scale using distributed state, replication, synchronization, and high-volume data-processing patterns.
- Strengthen service reliability through redundancy, automatic failover, recovery-oriented design, retries, circuit breakers, and timeouts.
- Develop and execute performance, load, and fault-injection tests to validate scalability, correctness, availability, and operational readiness.
- Create dashboards, alarms, telemetry, runbooks, and automation to detect issues proactively and accelerate recovery.
- Diagnose production issues, participate in on-call rotations and incident response, and contribute to root-cause analyses and durable corrective actions.
- Develop infrastructure automation and Infrastructure as Code for safe maintenance, troubleshooting, patching, updates, and rollbacks.
- Apply security controls, including encryption, access controls, and vulnerability remediation, in multi-tenant environments.
- Review peer implementations for scalability compliance.
- Meet change, compliance, and documentation standards.
