Position: Senior Software Engineer, Developer Experience
Location: New York

Core Weave is The Essential Cloud for AI. Built for pioneers by pioneers, Core Weave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence. Trusted by leading AI labs, startups, and global enterprises, Core Weave combines superior infrastructure performance with deep technical expertise to accelerate breakthroughs and turn compute into capability.

Founded in 2017, Core Weave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at .About the Team Core Weave  is The Essential Cloud for AI — the infrastructure that the world's leading AI labs, researchers, and enterprises depend on. The Developer Experience (Dev Ex) team owns the platform, services, and systems that enable every engineer at Core Weave 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.

What You'll DoSet technical direction for key Dev Ex 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 Dev Ex capabilities so engineers can delegate development tasks and move faster in an AI-native way.

Build for real scale. Dev Ex 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 patterns, and consistently raise the quality bar across the team.

Partner closely with infrastructure, security, and product engineering teams to design and implement developer experience foundations that are fast, safe, and compliant d post-mortems and drive continuous improvement cycles that harden Dev Ex systems against failure modes and reduce operational burden for engineering teams.

Set the standard for documentation and onboarding across the platform, so engineering teams at Core Weave can discover, adopt, and self-serve the tools your team builds.

What We're Looking For6+ years of software engineering experience with building production platforms, developer tooling, delivery infrastructure, or distributed storage systems.

Bachelor's degree in Computer Science, Engineering, or a related technical field.

Strong systems design skills. You think in distributed services, event-driven architectures, and APIs. You approach developer platform problems as software engineering problems, not configuration exercises.

Proficiency in Go, Python, or similar languages with production experience shipping services in cloud-native environments.

Deep experience with Kubernetes. You understand how workloads are…
