Senior Specialist Field Engineer - Compute Infrastructure

Title: Senior Specialist Field Engineer - Compute Infrastructure Location: London, UK

About the role

As a Senior Specialist Field Engineer - Compute Infrastructure at CoreWeave, you'll own the technical path for some of our largest customers as they go from facility and rack design to a validated, production-ready supercomputer. Working alongside the teams that build and operate each layer, you are the deep technical expert who turns raw data center hardware—racks, GPUs, high-speed fabric, firmware—into reliable compute that customers can train and inference on at scale, spanning infrastructure engineering, provisioning, validation, operations, and support.

You'll engage hands-on across the entire customer lifecycle: leading new GPU cluster bring-up and acceptance, driving InfiniBand/RoCE fabric validation and HPC performance benchmarking, defining how we operate customer bare-metal fleets at rack-level-and-up (IT service, break-fix, network, and firmware), and standing up locked-down, security-sensitive environments for our most strategic AI customers. You'll partner closely with Data Center Operations, Fleet Operations, Networking, and Product Engineering, and your work in the field will directly shape how CoreWeave delivers compute infrastructure. If you're driven by innovation, thrilled by the possibilities of what specialized compute can enable, and eager to be part of a team that's shaping the future, then CoreWeave is the place for you. Join us and let's embark on this adventure together!

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 offerings, focusing on bare-metal compute infrastructure and end-to-end cluster delivery within high-performance compute (HPC) environments.
• Own the technical path from facility and rack design to a validated, production-ready supercomputer—spanning logical design, infrastructure engineering, provisioning, validation, operations, and support.
• Lead bring-up and acceptance of new large-scale GPU clusters, driving InfiniBand/RoCE fabric validation, HPC performance benchmarking (e.g., NCCL, ib_write_bw), and remediation of fabric, optics, firmware, and node-level issues to meet customer performance targets.
• Define and operationalize models for managing customer bare-metal fleets at rack-level-and-up—IT service, break-fix, network and firmware management—including Bare Metal as a Service (BMaaS) and customer self-service patterns.
• 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 showcase the value and viability of CoreWeave's solutions within specific environments.
• Drive technical leadership and direction during customer meetings, presentations, and workshops, addressing any technical queries or concerns that arise.
• Act as a virtual member of CoreWeave's Compute Infrastructure, Fleet Operations, and Networking engineering teams, identifying opportunities for product enhancement and collaborating with engineers to implement your suggestions.

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 building or operating distributed systems or HPC/cloud services, with an expertise focused on bare-metal compute infrastructure and large-scale GPU cluster delivery
• Experience with modern rack-scale GPU server hardware (e.g., NVIDIA HGX, GB200/GB300, and Vera Rubin NVL72 systems)
• Expertise with high-speed interconnects (InfiniBand, RoCE, NVLink)
• Expertise with the firmware/BMC/BIOS layer
• Hands-on experience bringing up, validating, and operating large GPU clusters—including bare-metal PXE boot, hardware health, fabric validation, and HPC acceptance/performance testing—and integrating bare metal with orchestration layers such as Kubernetes and Slurm
• Expert-level Linux system administration and command-line troubleshooting, paired with strong networking fundamentals (routing, fabric topologies, TCP/IP)
• Proven track record with building customer relationships, communicating clearly and the ability to break down complex technical concepts to both technical and non-technical audiences

Preferred experience:

• Operating security-sensitive, air-gapped, or otherwise locked-down customer environments
• Scripting and automation related to bare-metal provisioning, infrastructure validation, and lifecycle management (Python, Bash, Ansible, or similar)
• Designing AI supercomputers from MEP designs
• Delivering bare-metal infrastructure at scale for large strategic customers or AI research labs
• Building solutions across multi-cloud or hybrid environments
