Senior Specialist Field Engineer - Compute Infrastructure

CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence.

The Field Engineering organization at CoreWeave is dedicated to ensuring every customer running AI workloads at scale has a seamless, reliable, and high-performance experience. This team supports the infrastructure that powers the AI revolution—working across data centers, hardware systems, and customer workloads to maintain the integrity of our cloud platform and shape the CoreWeave product roadmap.

As a Specialist Field Engineer – Compute Infrastructure, you will own the technical path for our largest customers from facility and rack design to a validated, production-ready supercomputer. You will be the deep technical expert who turns raw data center hardware—racks, GPUs, high-speed fabric, firmware—into reliable compute that customers can train and infer on at scale. Your work will span infrastructure engineering, provisioning, validation, operations, and support.

In this role, you will:

• Serve as the primary technical point of contact for customers, establishing strong technical relationships and ensuring their success with CoreWeave’s cloud infrastructure.
• Own the technical path from facility and rack design to a validated, production-ready supercomputer—spanning design, engineering, provisioning, validation, operations, and support.
• Lead bring-up and acceptance of new large-scale GPU clusters, drive InfiniBand/RoCE fabric validation, HPC performance benchmarking, and remediate fabric, optics, firmware, and node-level issues to meet performance targets.
• Define and operationalize models for managing customer bare-metal fleets at rack-level and above—including IT service, break-fix, network, and firmware management.
• Partner with Data Center Operations, Fleet Operations, and Networking teams to align facility, hardware, and fabric readiness with customer go-live timelines and operational SLAs.
• Review and advise on customer-facing technical contract terms, including service scope, operational responsibilities, SLAs, isolation requirements, and support boundaries.
• Lead proof of concept initiatives to demonstrate CoreWeave’s solutions within specific environments.
• Drive technical leadership during customer meetings, presentations, and workshops, addressing technical queries or concerns.
• Act as a virtual member of CoreWeave’s Compute Infrastructure, Fleet Operations, and Networking engineering teams, identifying product enhancement opportunities.
• Offer insights on product features, functionality, and performance, contributing to product strategy and architecture discussions.
• Stay informed on Kubernetes, cloud computing, and infrastructure trends, sharing thought leadership with customers and stakeholders.
• Lead the prototyping and initiation of research and development efforts for emerging products and solutions.
• Represent CoreWeave at conferences and industry events, traveling as required.

Who you are:

• B.S. in Computer Science or a related technical discipline, or equivalent experience.
• 7+ years of proven experience as a Solutions Architect, Field Engineer, Infrastructure/Systems Engineer, or Technical Account Manager in Cloud Infrastructure, focusing on bare-metal compute and large-scale GPU cluster delivery.
• Fluency in cloud computing concepts, architecture, and technologies with hands-on experience designing and implementing cloud solutions.
• Proven track record building customer relationships, communicating clearly, and breaking down complex technical concepts for diverse audiences.
• Deep expertise with modern rack-scale GPU server hardware, high-speed interconnects, and firmware/BMC/BIOS layers.
• Expert-level Linux system administration and command-line troubleshooting, with strong networking fundamentals (routing, fabric topologies, TCP/IP).
• Hands-on experience bringing up, validating, and operating large GPU clusters—including bare metal PXE boot, hardware health checks, fabric validation, HPC acceptance/performance testing, and integration with orchestration layers such as Kubernetes and Slurm.
• Preferred experience operating security-sensitive, air-gapped, or otherwise locked-down customer environments.
• Experience with scripting and automation related to bare-metal provisioning, infrastructure validation, and lifecycle management (Python, Bash, Ansible, or similar).
• Experience designing AI supercomputers from MEP designs.
• Experience delivering bare-metal infrastructure at scale for large strategic customers or AI research labs.
• Experience building solutions across multi-cloud or hybrid environments.
