Software Engineer, Infrastructure
Build and maintain infrastructure for a large fleet of GPU servers, including provisioning, health monitoring, diagnostics, recovery, storage optimization, and Linux tuning for AI workloads. Requires 3+ years managing large-scale bare-metal/cloud fleets, strong Python and deep Linux expertise.
About the job
Key Responsibilities
- Build and maintain Python fleet tracking system that manages the full lifecycle of servers including contracting and procurement, target use, pricing, availability, health, RMAs, etc.
- Build server management tooling that automates provisioning, health checks, GPU diagnostics, recovery and alerting.
- Create and maintain metrics, dashboards, and alerting for hardware health across the fleet (GPU errors, disk failures, network issues, thermals).
- Leverage AI to an extreme level to build tools and automate alerting and recovery.
- Implement and enforce OS-level security: hardening baselines, SELinux/AppArmor policies, SSH key management, vulnerability scanning, and compliance automation.
- Manage and optimize distributed and local storage systems supporting model weights, checkpoints, and ephemeral scratch: NVMe arrays, NFS, parallel file systems, and object storage.
- Tune Linux systems for AI workloads: kernel parameters, NUMA topology, CPU pinning, hugepages, I/O schedulers, and GPU driver stack optimization (NVIDIA drivers, CUDA, container runtimes).
- Develop a suite of automated error detection and recovery processes.
- Work with partners to solve technical issues.
Requirements
- 3+ years experience managing bare-metal and cloud based server fleets at scale (100+ nodes).
- Strong software engineering skills in Python; you write production tooling, not scripts.
- Deep Linux systems knowledge: boot process, kernel tuning, networking, storage, systemd, cgroups, namespaces, performance profiling.
- Strong experience with configuration management and infrastructure-as-code: Ansible, Terraform, cloud-init.
- Solid understanding of storage technologies: LVM, RAID, NVMe, NFS, Lustre or GPFS, and Linux I/O stack tuning.
- Familiarity with hardware diagnostics and failure modes (GPUs, NVMe, NICs, memory).
- Experience building internal tools or dashboards for infrastructure visibility.
- Excellent communication and ability to drive technical decisions across teams.
- Self-starter who executes quickly, takes ownership, and constantly seeks improvement.
Nice-to-Haves
- Familiarity with network configuration and diagnostics (VLAN, VXLAN, ECMP, BGP, tcpdump).
- Experience with NVIDIA GPU infrastructure: driver management, health monitoring, DCGM, NVLink/NVSwitch diagnostics, RDMA, InfiniBand/RoCEv2.
- Experience with AMD GPUs.
- Experience with bare metal and VM provisioning (PXE/iPXE, Kickstart, libvirt, Qemu/KVM).
- Experience with compliance frameworks relevant to cloud providers (SOC 2, ISO 27001).
