They have thousands of GPUs waiting. Their first month? Spent on cluster setup instead of research. Building deployment scripts, fighting container images, wiring up job orchestration. They came to train models. Instead, they're doing operations.</p> <p class="font-claude-response-body break-words whitespace-normal">This is the problem. We're building the Applied Training team to fix it.</p> <p class="font-claude-response-body break-words whitespace-normal">You'll be an early member of a small team, responsible for our Kubernetes-native research cluster platform, or the sandbox client for agentic training and evaluation, or possibly a new project altogether. The goal is specific: give every CoreWeave customer the research infrastructure that currently only exists inside frontier labs.</p> <h3 class="font-claude-response-body break-words whitespace-normal"><strong>In this role, you will:</strong></h3> <ul class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">Contribute to the roadmap for Applied Training — figure out what actually unlocks new workloads and what's just nice to have</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Work directly and closely with customers, and other teams inside CoreWeave that are building cloud native primitives: compute, storage, networking, etc.</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">For the research cluster platform: design and build a complete research cluster experience — CLI, job configuration schema, Kubernetes operators, daemons — solving the problems researchers actually hit: code distribution, checkpoint-triggered evaluation, cross-cluster scheduling, programmatic job control</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">For sandbox infrastructure: own the Python SDK and work in a tight loop with the backend team, enabling RL training runs to spawn thousands of isolated containers for agent rollouts and agent benchmarks at scale</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Write documentation for running popular OSS training frameworks on CoreWeave to unblock customers and help them succeed</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Work with infrastructure teams and customers directly — the customers are large AI labs running thousands of GPUs; understand how they structure their internal supercomputing stacks and bring that knowledge back to what we build</li> </ul> <h3 class="font-claude-response-body break-words whitespace-normal"><strong>Who You Are:</strong></h3> <ul class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="font-claude-response-body whitespace-normal break-words pl-2">8–12+ years building distributed systems, ML infrastructure, or developer platforms</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Real Kubernetes experience: custom controllers, operators, scheduling, CRDs, workload orchestration at scale — not just deploying things to Kubernetes or cluster administration</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">You understand what makes researchers productive: code distribution matters, fast iteration cycles matter, workflows that don't require becoming infrastructure experts matter</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Familiarity with training: how distributed jobs get scheduled, how ranks initialize, what breaks at scale</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">You've shipped infrastructure that other people rely on daily — not prototypes, production systems</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Strong communicator who can work…
