Senior Software Engineer (Developer Experience)

About this role

• CoreWeave is The Essential Cloud for AI™ — the infrastructure that the world’s leading AI labs, researchers, and enterprises depend on. The Developer Experience (DevEx) team owns the platform, services, and systems that enable every engineer at CoreWeave to build and ship software faster, more safely, and with greater confidence
• Our scope spans the full developer lifecycle: onboarding, developer environments, CLIs, SDKs, CI (continuous integration) and build infrastructure, test experience, delivery systems, artifact storage and distribution, internal developer platforms, and the agentic AI tooling that is redefining how engineers move from idea to production
• This is a high-leverage technical leadership role. You won’t be operating tooling — you’ll be designing and building the platforms other engineers depend on every day. The work you do will directly shape developer velocity, system reliability, and the agentic developer experience across a rapidly scaling engineering organization
• Set technical direction for key DevEx platform subsystems. Drive architectural decisions across SDKs, CLIs, inner development loop, CI pipeline infrastructure, test experience, artifact management, developer environments, and agentic tooling. Lead multi-quarter initiatives from design through production
• Design and build the core services that power developer productivity. Build pipeline services, test experience platforms, progressive rollout systems, artifact registries, ephemeral development environments, and the APIs that tie them together
• Architect and evolve our agentic developer platform. Elevate agentic DevEx capabilities so engineers can delegate development tasks and move faster in an AI-native way
• Build for real scale. DevEx systems must reliably serve thousands of application instances and engineering workflows across 40+ data centers with diverse infrastructure profiles
• Mentor other senior and mid-level engineers, own design reviews, establish engineering pat...
