Senior Software Engineer, Developer Experience

Weights & Biases Weights & Biases · Data AI · Bellevue, WA +4 · Technology

Senior Software Engineer focused on Developer Experience (DevEx) at CoreWeave, an AI cloud provider. The role involves designing and building platforms, services, and systems that enhance developer productivity, reliability, and the adoption of agentic AI tooling across the engineering organization. Key responsibilities include setting technical direction, architecting agentic developer platforms, and ensuring systems scale to serve thousands of instances.

What you'd actually do

  1. Set technical direction for key DevEx platform subsystems. Drive architectural decisions across CI pipeline infrastructure, test experience, artifact management, developer environments, and agentic tooling. Lead multi-quarter initiatives from design through production.
  2. 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.
  3. 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.
  4. Build for real scale. DevEx systems must reliably serve thousands of application instances and engineering workflows across 40+ data centers with diverse infrastructure profiles.
  5. Mentor Senior I and mid-level engineers, own design reviews, establish engineering patterns, and consistently raise the quality bar across the team.

Skills

Required

  • 7+ years of software engineering experience with building production platforms, developer tooling, delivery infrastructure, or distributed storage systems.
  • Strong systems design skills.
  • Proficiency in Go, Python, or similar languages with production experience shipping services in cloud-native environments.
  • Deep experience with Kubernetes.
  • Experience with or strong technical interest in LLM-integrated developer tooling, such as agent frameworks, MCP-style tools, or AI-assisted developer workflows.
  • Proven track record of setting technical direction, making sound architectural trade-offs, and driving engineering decisions that hold up as systems and teams scale.
  • Effective cross-functional collaborator.
  • Experience mentoring engineers and consistently raising the technical quality bar of the teams you work on.

Nice to have

  • Experience building or extending CI and build infrastructure at scale, including GitHub Actions, Buildkite, Bazel, or similar build systems.
  • Experience designing and operating progressive delivery systems at scale, including SLO-based quality gates, automated multi-stage pipeline orchestration, and custom Kubernetes operators, across heterogeneous deployment environments.
  • Hands-on experience with artifact management, including distributed storage, caching, versioning, or multi-region artifact distribution (e.g. JFrog Artifactory, Cloudsmith, or custom-built systems).
  • Direct experience building agentic systems, including MCP servers, tool-augmented LLM workflows, and incorporating these capabilities into DevEx platform features with consistent value-add.
