Senior Platform Security Engineer (Zero Trust and Platform Security)

Role Overview

Senior Platform Security Engineer focused on Zero Trust and Platform Security within a GPU-native cloud platform for AI training/inference and HPC workloads. You will bridge the existing production platform with a next-generation orchestration architecture, owning critical orchestration components with deep hands-on engineering.

Missions / Responsibilities

• Design, build, and operate the compute orchestration layer for a cloud-native GPU platform.
• Maintain and evolve CloudStack-based deployments while contributing to the design of the next-generation compute platform.
• Collaborate with networking, storage, and platform engineers to integrate core platform primitives.

Requirements

• Experience running GPU-heavy infrastructure for AI training, inference, or HPC workloads.
• Proven experience with large-scale distributed compute environments (neo-cloud, hyperscaler, or HPC provider).
• Strong experience with CloudStack internals (extending and maintaining platform functionality).
• Production experience operating cloud orchestration platforms.
• Experience designing/operating control-plane services for infrastructure platforms.
• Experience maintaining or extending large Java codebases (preferably in infrastructure/platform contexts).
• Strong programming skills in Go and Python for cloud-native platform components.
• Familiarity with workflow orchestration systems, e.g. Argo Workflows.
• Deep practical knowledge of Kubernetes internals and Slurm scheduling systems.
• Experience building/operating compute orchestration layers for large-scale clusters.
• GPU infrastructure experience including passthrough, NVIDIA MIG, scheduling, and GPU lifecycle management.
• Understanding of GPU virtualization/passthrough (e.g., QEMU PCI passthrough, NVIDIA MIG).
• Familiarity with virtual/distributed networking: OVS, OVN, VPC networking, RDMA/RoCE, ECMP, EVPN/VXLAN, leaf-spine fabrics.
• Ability to solve complex implementation/operational problems across CloudStack, Kubernetes, Slurm, and workflow orchestration; improve orchestration quality via code/automation and practical design decisions.
• Comfortable mentoring peers and improving documentation, operational workflows, and platform reliability.
• Ability to independently own major compute-orchestration initiatives from design through rollout and operational stabilization.

Nice to Have

• Strong platform security/Zero Trust alignment (implied by role title) applied to orchestration/control-plane components.
