Rural broadband provider with hybrid FTTM
Boundless Networks, Inc. · United States (Remote) · Full-time · Posted 2026-08-03
Salary: USD 175,000–250,000
Workplace: remote
Department: Boundless Team
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.
What You'll Do
GPU Fleet Orchestration: 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.
Compute Scheduling & Utilization: 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.
Bare-Metal & GPU Optimization: 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.
Reliability, Access & Observability: Build secure fleet access (Tailscale, Teleport), robust observability and alerting, and zero-downtime rollouts across a distributed node fleet.
Cost Optimization: Drive down $/GPU-hr through spot instance management, intelligent workload placement between on-prem and cloud, and resource scheduling — without sacrificing reliability.
Nice to Have

Rural broadband provider with hybrid FTTM
Boundless Networks provides high-speed broadband in rural and hard-to-reach areas of the North of England using its own private network. Its Fibre-to-the-Mast setup brings fibre to masts and then uses wireless links to deliver services up to 1 Gbps to homes and businesses without a traditional phone line. It combines full-fibre and fixed-wireless technologies and operates independently, with a 2021 partnership where Quickline acquired a 51% stake to scale the hybrid network while Boundless continues to operate under its own name. Its goal is to close the digital divide by expanding reliable, gigabit-capable last-mile connectivity in Yorkshire and nearby counties.
