Native Developer Jobs in California (NOW HIRING)

Job Summary:
CoreWeave is The Essential Cloud for AI™, delivering a platform of technology and tools for innovators to build and scale AI. The Principal Software Engineer for Developer Experience will define the long-term technical direction, improve developer productivity, and lead cross-team initiatives to enhance engineering velocity and software quality.
Responsibilities:
• Define and drive the technical strategy for Developer Experience across build systems, test systems, delivery platforms, developer tooling, and agentic engineering capabilities.
• Own delivery at scale. Define and drive the strategy for how code goes from commit to production reliably and quickly. Attack the bottlenecks — CI/CD throughput, build and test times, deployment safety, rollback speed, and release orchestration — across a large, multi-team codebase.
• Architect and evolve the core services, APIs, SDKs, and software abstractions that power how engineers build, test, deploy, and operate software at CoreWeave.
• Lead cross-team technical initiatives that improve engineering velocity, software quality, and system reliability at organizational scale.
• Solve high-complexity software engineering problems involving distributed systems, service architecture, performance, scalability, concurrency, and failure handling.
• Identify systemic bottlenecks in developer workflows and design durable software solutions that reduce friction without increasing operational complexity.
• Establish technical standards and best practices for code quality, maintainability, testability, observability, and long-term system design across the engineering organization.
• Partner with infrastructure, security, SRE, and product engineering teams to ensure DevEx systems integrate cleanly into the broader technical ecosystem.
• Mentor senior engineers, raise the technical bar across teams, and help grow the next generation of staff-plus engineering leadership.
• Design agent-safe developer interfaces and tooling that integrate LLM-driven workflows into the build, test and code review lifecycle - ensuring automation, AI-assisted tooling and human-in-the-loop systems are first class , well governed parts of developer experience.
• Define and maintain the internal developer platforms' golden paths, service templates, and paved road abstractions that make it easy for engineers to do the right thing by default.
Qualifications:
Required:
• 10+ years of software engineering experience, including significant time designing, building, and owning large-scale production software and distributed systems.
• Proven ability to define multi-year technical strategy and execute across complex, cross-team domains.
• Deep systems design expertise with strong opinions on API design, service architecture, data models, software abstractions, correctness, scalability, and long-term maintainability.
• Strong software engineering fundamentals and proficiency in Go, Python, or similar languages, with a track record of shipping high-quality production services in cloud-native environments.
• Deep experience debugging complex production issues and reasoning through distributed system behavior, performance bottlenecks, and failure modes.
• Strong experience designing developer-facing software such as internal platforms, APIs, CLIs, SDKs, workflow engines, or other tooling that engineers rely on every day.
• Deep understanding of Kubernetes and modern software delivery environments, with the ability to make sound architectural decisions in cloud-native systems.
• Demonstrated ability to influence technical decisions at the organizational level and communicate clearly with both technical and non-technical stakeholders.
• A track record of mentoring senior engineers and raising technical quality across teams.
Preferred:
• Deep expertise in one or more DevEx domains such as build systems, test infrastructure, CI/CD, remote execution, caching, artifact systems, or developer environments.
• Hands-on experience designing and operating large-scale distributed services that support high-throughput engineering workflows.
• Experience building internal developer products with a strong focus on usability, API ergonomics, adoption, and long-term maintainability.
• Experience with AI-native developer tooling, including LLM-integrated workflows, agentic frameworks, MCP-style tooling, or autonomous developer agents with strong safety and governance patterns.
• Prior experience serving as a technical lead or system architect on a software platform with broad organizational impact.
• Kubernetes operator development, CRD design, or control-plane work — especially in the context of managing developer workloads or CI/CD infrastructure on Kubernetes.
• Prior experience at a cloud infrastructure company, hyperscaler, or HPC environment where engineering scale and compute heterogeneity create unique DevEx challenges.
• Familiarity with container runtimes, OCI image standards, or artifact distribution systems at scale.
