Senior Infrastructure Engineer

📋 Job Overview

Boundless is coordinating GPU compute at scale as it becomes a leader in AI. As a Senior Infrastructure Engineer (GPU Compute), you'll build and operate the compute fabric that powers our AI inference workloads — a large, heterogeneous, globally distributed GPU fleet spanning consumer cards (including RTX 5090) and datacenter hardware. Your job is to keep that fleet full, fast, cheap, and always on: orchestrating workloads across regions and providers, squeezing every bit of performance out of the hardware, and driving down cost per GPU-hour. This role rewards engineers who want to go deep on bare-metal and GPU optimization.

You should be comfortable operating with a high degree of autonomy, navigating ambiguity, and defaulting to a strong bias for action.

🏢 About Boundless Networks, Inc.

Boundless is a company at the forefront of AI compute infrastructure, focusing on GPU orchestration and optimization for large-scale inference workloads.

🎯 The Role

You will be responsible for operating a heterogeneous, multi-region GPU fleet using tools like SkyPilot, Kubernetes/k3s, and cloud + on-prem providers. You'll build patterns for scheduling inference workloads across the entire fleet reliably, maximize GPU utilization, and optimize bare-metal and GPU performance.

✅ Key Responsibilities

• Operate a heterogeneous, multi-region GPU fleet (consumer + datacenter, including RTX 5090) using tools like SkyPilot, Kubernetes/k3s, and cloud + on-prem providers.
• Build the patterns that let us schedule inference workloads across the entire fleet reliably.
• Maximize GPU utilization across inference workloads.
• Own workload placement across spot, on-prem, and cloud capacity, keeping the "always-on inference substrate" saturated and economical.
• Go deep on GPU performance — PCIe P2P, ReBAR, NUMA topology (e.g. EPYC SP5), CUDA/driver tuning, memory configuration, and network topology — to push throughput per node.
• Build secure fleet access (Tailscale, Teleport), robust observability and alerting, and zero-downtime rollouts across a distributed node fleet.
• Drive down $/GPU-hr through spot instance management, intelligent workload placement between on-prem and cloud, and resource scheduling — without sacrificing reliability.

📌 Required Qualifications

• 5+ years of infrastructure/DevOps experience operating large-scale production systems
• Deep expertise in Kubernetes, Docker, and container orchestration at scale
• Strong Linux systems administration skills
• Proficiency in infrastructure-as-code tools (Terraform, Ansible, Pulumi)
• Track record of managing mission-critical, high-throughput systems
• Strong infrastructure-as-code background in heterogeneous environments
• Proficiency in at least one common scripting or programming language (Python, Bash, TypeScript, Go, etc.)
• Comfort navigating ambiguity with a strong bias for action

⭐ Desirable Experience

• Experience with GPU computing infrastructure (CUDA, bare-metal optimization, kernel tuning)
• Experience operating ML training or other large-scale distributed compute infrastructure
• Experience with GPU fleet orchestration (SkyPilot, Ray, Slurm)
• Familiarity with fleet access and networking tooling (Tailscale, Teleport)
• Knowledge of network optimization and topology design
• Experience with multi-region, globally distributed systems
• Proficiency in Rust or low-level systems programming
• Experience with on-premises data center operations

🎁 Benefits

Competitive salary (proposed band b/t US$175k and $250k annually) + equity allocation
Health, dental, vision (for U.S. employees; region-adjusted globally)
Flexible PTO
Professional development and conference travel budget
Remote-first with regular off-sites and a high-trust, high-velocity team environment

🛂 Visa & Eligibility

Candidates must include a public GitHub profile in their application. The GitHub profile should demonstrate a minimum of 1 year of activity/history. Applications that do not include a GitHub profile, or show insufficient activity, will not be considered.
