Infrastructure Systems Engineer III or Sr - Linux

This position may be filled at multiple levels depending on the candidate’s experience and qualifications.

We are building a modern, software‑defined infrastructure platform designed to support the next generation of applications across the organization.

This platform is designed around open‑source technologies, commodity hardware, and automation‑first principles. It provides the core compute, storage, networking, and container runtime capabilities required to run distributed systems at scale across both data centers and cloud environments.

This is a greenfield engineering effort focused on defining how infrastructure is built and operated using code, APIs, and declarative systems, with reliability, observability, and repeatability designed in from the start.

• Linux‑first systems design
• Kubernetes as a core abstraction layer
• Infrastructure‑as‑code and Git Ops workflows
• Open observability standards (Prometheus, Open Telemetry)
• Distributed, software‑defined storage and networking

Engineers on this team build and own foundational systems that applications across the organization rely on for secure, reliable operation.

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.
