Job summary

Saige Partners in San Jose is seeking a hands-on systems engineer to own end-to-end software spanning Linux, Kubernetes, and cloud platform interfaces. You will work across kernel and user-space boundaries, develop operators and automation, and collaborate with hardware teams to deliver observable, scalable solutions for enterprise storage.

This onsite role demands strong systems design, debugging, and performance tuning in lab and production environments.

Qualifications

• Experience with Linux kernel and host OS integration.
• Strong understanding of distributed systems concepts.
• Familiarity with observability, debugging and tracing in complex systems.
• Knowledge of memory management concepts (e.g., NUMA, cgroups) is a plus.

Responsibilities

• Architect and implement end-to-end systems software across Linux and Kubernetes environments.
• Design solutions spanning kernel/user-space, container runtimes, and Kubernetes APIs/CRDs.
• Develop and maintain Kubernetes operators, controllers, and automation services using Go.
• Collaborate with kernel, firmware, and hardware teams to translate platform capabilities into Kubernetes workflows.

Job description

Join us at Saige Partners, where we aim to shape your future and be the solution that propels your career forward! Onsite in San Jose, CA

What You’ll Do

Work across the full stack: from host memory and device behavior in Linux, to node agents and container runtime interactions, to Kubernetes resource orchestration, controllers, and cluster-level lifecycle management. This is a hands‑on systems role for an engineer who is comfortable working across boundaries that are often split between kernel and cloud platform teams.

• Architect and implement end‑to‑end systems software for advanced platform and memory technologies across Linux and Kubernetes environments.
• Design solutions that span: o Linux kernel and host OS integration o user‑space system services and node agents o container runtime / kubelet interaction points o Kubernetes APIs, controllers, CRDs, and orchestration workflows
• Develop software for resource discovery, reservation, activation, resize, release, rollback, and reconciliation in clustered environments.
• Build and maintain Kubernetes operators, controllers, and automation services using Go, client‑go, controller‑runtime, and related frameworks.
• Collaborate with Linux, firmware, and hardware teams to translate low‑level platform capabilities into safe, observable, Kubernetes‑manageable workflows.
• Work on Linux‑side integration for areas such as memory lifecycle, hotplug behavior, NUMA awareness, cgroups, device/resource management, and system telemetry.
• Define interfaces between host software and cluster control‑plane components, including state models, failure handling, and recovery behavior.
• Develop node‑local software and control‑plane services that coordinate host state, platform services, and Kubernetes objects.
• Drive architecture for reconciliation, idempotency, concurrency control, and fault recovery across distributed components.
• Create observability for controller behavior, node readiness, resource lifecycle progress, and failure analysis.
• Partner with internal teams across kernel, systems architecture, firmware, validation, and platform software to bring proof‑of‑concept software into robust internal infrastructure.
• Support bring‑up, debugging, validation, and performance tuning in lab and pre‑production environments.

Join our team and help shape the future of enterprise storage technology. Your work will have a global impact, powering performance‑driven solutions for the world’s most demanding applications.
