Senior / Staff Infrastructure Security Engineer

Job summary

Responsibilities

We’re looking for a Senior or Staff Infrastructure Security Engineer to secure the cloud that runs Suno. That covers our Kubernetes clusters, the GPU compute behind our AI workloads, and the network that connects them.

• Build Suno’s infrastructure threat model across cloud, Kubernetes, GPU compute platforms, and networking, and use it with the Security Lead to decide where to focus first.
• Harden our EKS clusters, GPU compute environments, and infrastructure-as-code pipeline, including who can change infrastructure and how.
• Design paved paths and secure defaults, such as trusted base images, network segmentation, and scoped access, and ship the fixes yourself rather than handing off a list of…
• Define the infrastructure detections and alerts we need beyond out-of-the-box tooling, working with Detection & Response, and be the expert they call when those alerts fire.
• Partner with Platform Engineering and the broader engineering org to land changes in a fast-moving environment, and help shape a growing Security team.

What they're looking for

• At least 7 years of experience in infrastructure security or adjacent fields.
• An engineering background building secure-by-default tooling and paved paths, not primarily running scans and reporting findings.
• Hands-on depth in cloud-native security (AWS preferred; GCP or Azure are fine), plus Kubernetes and container security, including image provenance and software supply chain…
• Strong enough coding skills to build your own tooling and implement fixes without needing another engineer to carry them out.
• End-to-end ownership of security projects, with the comfort to build in a greenfield environment where structure is still taking shape.
