Work type: remote
Location: Remote - United States
Salary: $165,000 – $185,000/yr
Type: Full-time
This role is designed for a heavyweight infrastructure expert with at least 7 years of experience in high-performance computing (HPC) or hyperscale environments. You are the ideal candidate if you possess a rare blend of networking expertise (InfiniBand/RoCE) and physical facility awareness. You should be comfortable calculating power envelopes and thermal loads just as easily as you design non-blocking network topologies for tens of thousands of GPUs. The compensation is competitive ($165k–$185k) for a fully remote U.S. role, but the real draw is the benefits package. Vultr offers 100% company-paid medical/dental premiums, a 4% 401(k) match with immediate vesting, and a unique longevity program including a one-month paid sabbatical every five years. As a mid-level architect in a company recently valued at $3.5 billion, you’ll have a front-row seat to scaling one of the world's largest private clouds. **You might be a good fit if you...** * Can design complex network fabrics like Clos or Dragonfly while accounting for switch radix and link speeds. * Have deep knowledge of GPU hardware (NVIDIA/AMD), NVLink, and PCIe node topologies. * Enjoy the "Tetris" of capacity planning—maximizing GPU density within strict power and cooling limits. * Are a documentation pro who can translate vendor SKUs into scalable architectural templates.
## Who We Are
Vultr is on a mission to make high-performance cloud infrastructure easy to use, affordable, and locally accessible for enterprises and AI innovators around the world. With 32 global cloud data center locations, Vultr is trusted by hundreds of thousands of active customers across 185 countries for its flexible, scalable, global Cloud Compute, Cloud GPU, Bare Metal, and Cloud Storage solutions. In December 2024 Vultr announced an equity financing at a $3.5 billion valuation. Founded by David Aninowsky and self-funded for over a decade, Vultr has grown to become the world’s largest privately-held cloud infrastructure company.
## Vultr Cares
Vultr is looking for an AI Cluster Architect who will be responsible for creating and refining large-scale GPU cluster architectures within strict power and infrastructure limits. This role focuses heavily on power-aware design: starting from a fixed power envelope, the architect determines the optimal number of GPUs while accounting for the full stack of services needing to be deployed—compute nodes, storage systems, networking fabric, cooling, and facility constraints. This role requires deep experience navigating heterogeneous environments, multiple generations of hardware, and end user requirements.
The architect must understand how different GPU SKUs, NICs, switches, and fabrics interact at scale, including their individual and aggregate power and thermal characteristics. They will evaluate multi-plane, rail-optimized, and tiered fabric designs across technologies like InfiniBand, RoCE, and SpectrumX to ensure the networking architecture supports the intended GPU count without overrunning facility limits or switch radix and/or topology constraints. This role balances customer-specific requirements for compute, storage, and service density, ensuring that the final cluster design maintains acceptable levels of GPU and fabric performance, while maximizing the number of usable GPUs within the total power budget.
