Job summary

fal is building a scalable generative media platform and you will own the software and processes that keep thousands of GPU servers healthy. You will write production tooling in Python, automate provisioning and monitoring, and drive security and reliability decisions across teams.

You’ll work on OS hardening, storage architectures, and high-availability systems while collaborating with partners to resolve complex infrastructure challenges and enable rapid AI development.

Qualifications

• 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 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.

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 episodic 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
