Senior Software Engineer II, Applied Training

What You’ll Do A lab signs with CoreWeave. 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. This is the problem. We're building the Applied Training team to fix it. In This Role, You Will Contribute to the roadmap for Applied Training — figure out what actually unlocks new workloads and what's just nice to have Work directly and closely with customers, and other teams inside CoreWeave that are building cloud native primitives: compute, storage, networking, etc. 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 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 Write documentation for running popular OSS training frameworks on CoreWeave to unblock customers and help them succeed 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 Who You Are 8–12+ years building distributed systems, ML infrastructure, or developer platforms Real Kubernetes experience: custom controllers, operators, scheduling, CRDs, workload orchestration at scale — not just deploying things to Kubernetes or cluster administration You understand what makes researchers productive: code distribution matters, fast iteration cycles matter, workflows that don't require becoming infrastructure experts matter Familiarity with training: how distributed jobs get scheduled, how ranks initialize, what breaks at scale You’ve shipped infrastructure that other people rely on daily — not prototypes, production systems Strong communicator who can work with customers and translate researcher complaints into system designs Preferred Experience building internal ML platforms or research clusters at a company doing large-scale training Familiarity with agentic AI: RL training with rollouts, agent evaluation, sandbox isolation for running untrusted code Background with Slurm, Ray, or similar workload orchestration, and opinions on where they fall short Experience with container runtimes, isolation (gVisor, Kata), or serverless platforms OSS contributions to Kubernetes SIGs, Ray, PyTorch, or similar What We Offer The base salary range for this role is $182,000 - $242,000.
