Staff Software Engineer, Developer Experience

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

Staff Software Engineer focused on Developer Experience, specifically owning the technical strategy and execution for the agentic developer platform. This role involves defining the architecture for CI, build infrastructure, test experience, delivery systems, and artifact management, with a strong emphasis on evolving agentic systems and autonomous workflows to improve developer productivity.

What you'd actually do

  1. Define and drive the technical strategy for the DevEx platform. Set the long-term architectural direction across CI pipeline infrastructure, test experience, delivery systems, artifact management, and agentic developer tooling, balancing engineering excellence with business priorities and org-wide scale.
  2. Solve the highest-complexity developer productivity problems at CoreWeave. Identify systemic bottlenecks that span teams, design solutions that operate reliably across 40+ data centers, and drive execution from architecture through production.
  3. Lead the agentic developer platform from a technical standpoint. Evolve the architecture of MCP servers, tool integration, and agent-accessible DevEx APIs so that autonomous workflows become a first-class primitive for every engineer at CoreWeave.
  4. Drive cross-team technical initiatives. Work across DevEx, infrastructure, security, SRE, and product engineering to align on platform direction, resolve deep architectural trade-offs, and establish engineering standards that raise the bar org-wide.
  5. Mentor and develop Senior II engineers. Actively coach ICs, elevate technical decision-making across the team, and build the engineering depth needed to sustain DevEx as CoreWeave scales.

Skills

Required

  • 10+ years of software engineering experience with significant time spent building and owning production developer platforms, build infrastructure, or large-scale distributed systems.
  • Demonstrated ability to define and execute multi-year technical strategies across complex, cross-team domains.
  • Deep systems design expertise.
  • Proficiency in Go, Python, or similar languages with a track record of shipping large-scale production services in cloud-native environments.
  • Expertise in Kubernetes and IaaC (Infrastructure as Code) at the platform design level.
  • Experience with or strong leadership interest in AI-native developer tooling, including agentic frameworks, LLM-integrated developer workflows, or autonomous software development agents.
  • Proven ability to influence technical decisions at the organization level, build alignment across teams with competing priorities, and communicate clearly with engineering leadership.
  • A track record of growing senior engineers and building technical strength in the teams around you.

Nice to have

  • Deep expertise in one or more DevEx domains, including large-scale CI, build and test systems (Bazel, Buildkite, remote execution, caching), deployment (GitOps, ArgoCD), artifact storage and distribution, or ephemeral development environment infrastructure.
  • Hands-on 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.
  • Experience architecting and landing agentic systems at scale, including designing MCP servers, agent governance models, or tool-augmented LLM workflows that operate reliably in production with consistent user-facing value-add.
  • Prior experience as a technical lead or system architect on a platform or infrastructure team with broad engineering org impact.
