Infrastructure Systems Engineer III or Sr...

This role will be responsible for designing, building, and operating the foundational infrastructure that powers the company’s technology platform. This includes compute, storage, networking, and container infrastructure supporting enterprise applications, internal platforms, and hybrid cloud environments.

This role focuses on delivering reliable, scalable, and automated infrastructure platforms across data centers and cloud environments. Infrastructure engineers operate the foundational platforms that support modern workloads, including virtualization platforms, storage systems, networking, and container infrastructure such as Kubernetes clusters.

RESPONSIBILITIES

• Key Responsibilities

Infrastructure Engineering

• Design, deploy, and operate infrastructure platforms including compute, storage, networking, and container infrastructure

• Build and maintain scalable infrastructure across on-premises data centers and cloud environments

• Operate and support Kubernetes clusters and their underlying infrastructure

• Ensure high availability, reliability, and performance of infrastructure systems

• Support hybrid infrastructure environments and platform services that run on top of them

Automation & Infrastructure as Code

• Develop and maintain infrastructure automation using modern programming languages (Go, Python, Java)

• Implement infrastructure provisioning and configuration through infrastructure-as-code tools such as Terraform

*Bachelor’s degree in management information systems (MIS), computer science, or related technical field; or equivalent work experience. (Typically, four years of related, progressive work experience would be needed for candidates applying for this position who do not possess a bachelor’s degree.)

• Six years of experience in infrastructure, platform, or site reliability engineering roles for the level III

• Strong experience working with Linux systems and distributed infrastructure environments

• Proficiency in at least one modern programming language, such as Go, Python, or Java

• Experience automating storage provisioning, data protection, and lifecycle management using infrastructure-as-code or API-driven approaches

• Experience with software-defined or distributed storage architectures designed to run on commodity hardware

• Experience automating backup, restore, and recovery workflows to reduce manual intervention and operational risk

Core Technical Experience

Experience across several of the following areas:

• Linux systems and core infrastructure fundamentals

• Kubernetes and container orchestration platforms

• Infrastructure as code and declarative system design (e.g., Terraform, GitOps)

• Distributed systems and large-scale infrastructure environments

• Observability and monitoring using open-source tooling (e.g., Prometheus, Grafana, OpenTelemetry)

• Distributed storage systems and concepts (e.g., Ceph or similar technologies)

• Networking fundamentals in distributed and cloud-based environments

• API-driven infrastructure and automation systems

• Infrastructure security practices, including identity, access, and secrets management

• Hybrid infrastructure spanning on-premises data centers and cloud environments

Preferred Qualifications:

• Experience operating Kubernetes clusters at scale

• Experience with GitOps workflows such as ArgoCD or Flux

• Experience supporting streaming data platforms or messaging systems

• Experience with SQL, NoSQL, or graph databases

• Contributions to open-source infrastructure or platform projects
