About The Role

Leads development and begins architecting components of scalable, elastic distributed systems for the Network Automation Team. Defines and enforces scalability requirements for owned components; optimizes code and data paths for high‑throughput, hyper‑scale workloads; and leverages data plane platforms for large‑scale retrieval, storage, and processing. Designs fault‑tolerant, in‑service‑upgradable systems using redundancy, replication, failover, and policies for partitions, applying load‑shedding, throttling, and rate‑limiting to handle network unreliability while meeting SLOs. Establishes KPIs and telemetry; builds proactive dashboards and alerts; and designs complex validation (fault injection, brownouts), replication, and synchronization for correctness and durability. Proactively diagnoses and resolves production issues, mentors peers, and ensures operational readiness. Implements robust security controls, executes remediation, maintains compliance documentation, and develops IaC and automation that enable safe patching, updates, and rollbacks within change‑management plans.

We are seeking a Core Infrastructure Engineer to design, build, and operate the distributed systems that power reliable, secure, and scalable cloud services. This role combines hands-on engineering, systems thinking, operational leadership, and mentorship.

This position is based out of Nashville,TN.

Key Responsibilities

System Design & Architecture: Scalability

Lead the development, implementation, and architectural evolution of scalable distributed-system components that support horizontal and vertical growth, including distributed state-management tools.
Optimize code and systems for large-scale data processing and high-throughput workloads in hyperscale environments.
Define scalability requirements for owned components and ensure designs and implementations satisfy them.
Design for elastic capacity, enabling systems to scale up and down efficiently with demand.
Use data-plane platforms to support large-scale data retrieval, storage, and processing.
Design and execute performance and load-testing strategies.

System Design & Architecture: Reliability

Build fault-tolerant components and systems that withstand in-service updates through redundancy, replication, and automatic failover.
Design systems to manage service disruptions, including network partitions, with explicit tradeoffs among consistency, availability, and partition tolerance.
Implement and optimize resilience mechanisms for network unreliability, including load shedding, throttling, and rate limiting.
Design durable components and systems that meet service-level objectives (SLOs) and establish clear availability and durability expectations for dependent services.

System Reliability: Performance, Observability & Correctness

Define key performance indicators (KPIs) and telemetry that reveal gaps and issues in production systems.
Build and tailor dashboards, telemetry pipelines, and alerting mechanisms to proactively monitor component and system health.
Design and implement functional and correctness requirements for features and systems, whether new or existing.
Design complex test scenarios, including fault-injection and brownout testing, to validate system correctness.
Implement data replication and synchronization techniques that preserve data integrity and availability.

Operational Troubleshooting & Incident Management

Proactively diagnose, debug, and resolve issues in active components and systems; mentor others in effective troubleshooting practices.
Implement approaches that avoid customer maintenance windows when resolving issues and minimize service interruption.
Maintain deep expertise in owned components and systems to enable effective troubleshooting and performance optimization.
Meet operational-readiness expectations through thoughtful design and implementation.
Participate in operational support rotations and provide leadership during incident response and root-cause investigations.

Security, Compliance & Change Management

Implement security measures for multi-tenant environments, including encryption and access controls that protect data and applications.
Execute remediation plans to close identified security gaps.
Ensure cloud infrastructure complies with applicable industry standards and regulations, with current supporting documentation.
Develop and maintain automation tools and infrastructure-as-code (IaC) to manage cloud infrastructure.
Create and follow change-management plans for patching, updates, and rollbacks; design systems that increasingly automate these processes.

Core Responsibilities

Planning & Execution

Manage and coordinate moderately complex work, tracking timelines and deliverables to ensure timely, high-quality completion. Delegate, prioritize, and provide technical oversight across multiple projects, adapting plans as resourcing or timelines change.

Collaboration & Partnership

Collaborate across the organization to align expectations and achieve shared objectives. Apply an understanding of leaders, stakeholders, and customers to ensure solutions meet real needs, and actively seek diverse perspectives so colleagues feel heard and respected.

Problem Solving

Analyze a broad range of data and information to resolve moderately complex issues using sound engineering practices. Escalate critical or unresolved issues with a clear assessment and proposed options, and document problem-solving approaches for reuse.

Continuous Learning & Mentorship

Expand knowledge of new technologies, tools, and industry practices. Seek and apply feedback to improve performance, and coach junior team members through active knowledge sharing within and across teams.

Continuous Improvement

Develop ideas and recommend or implement process improvements that increase the efficiency and effectiveness of team workflows. Solicit feedback on alternative approaches and assess the impact on key stakeholders.
