Senior Software Engineer (Developer Experience)

CoreWeave; York and North Yorkshire; On-site; GBP 90,000 - 150,000; Full time

Job summary

CoreWeave is seeking a high-impact leader to shape the Developer Experience platform. You will set direction for DevEx subsystems, drive multi-quarter initiatives, and build core services that accelerate developer productivity across AI tooling and cloud-native environments.

You will mentor engineers, design scalable architectures, and collaborate with infrastructure, security, and product teams to deliver fast, safe, and compliant foundations at scale.

Qualifications

• 6+ years of software engineering experience with building production platforms, developer tooling, delivery infrastructure, or distributed storage systems.
• Experience setting technical direction, making architectural trade-offs, and driving engineering decisions as teams scale.
• Strong systems design skills across distributed services, event-driven architectures, and APIs.
• Deep experience with Kubernetes, understanding workload packaging, scheduling, and cluster integration.
• Proficiency in Go, Python, or similar languages with production experience shipping cloud-native services.
• Effective cross-functional collaboration to align stakeholders and translate complex trade-offs.
• Hands-on experience with artifact management (distributed storage, caching, versioning, multi-region distribution).
• Experience designing progressive delivery systems (SLO-based gates, multi-stage pipelines, Kubernetes operators).
• Experience building or extending CI and build infrastructure (GitHub Actions, Buildkite, Bazel).
• Direct experience building agentic systems (MCP servers, LLM workflows) within DevEx platforms.
• 6+ years of software engineering experience building production platforms or distributed systems.

Responsibilities

• Set technical direction for DevEx platform subsystems and drive architectural decisions across SDKs, CLIs, CI pipelines, and artifact management.
• Lead multi-quarter initiatives from design through production.
• Design and build core services powering developer productivity such as pipeline services and agentic tooling.
• Architect and evolve the agentic developer platform to accelerate engineering throughput.
• Scale DevEx systems to thousands of instances across data centers; ensure reliability and safety.
• Mentor senior and mid-level engineers and establish engineering patterns and quality bars.
• Collaborate with infrastructure, security, and product teams to ensure fast, safe, and compliant foundations.
• Lead post-mortems and continuous improvement cycles to harden systems.

Job description

• 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 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 at scale
• Lead post-mortems and drive continuous improvement cycles that harden DevEx 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 CoreWeave can discover, adopt, and self-serve the tools your team builds

Experience with or strong technical interest in LLM-integrated developer tooling, such as agent frameworks, MCP-style tools, or AI-assisted developer workflowsProven track record of setting technical direction, making sound architectural trade-offs, and driving engineering decisions that hold up as systems and teams scaleExperience mentoring engineers and consistently raising the technical quality bar of the teams you work onStrong systems design skills. You think in distributed services, event-driven architectures, and APIs. You approach developer platform problems as software engineering problems, not configuration exercisesDeep experience with Kubernetes. You understand how workloads are packaged, scheduled, and managed at the cluster level, and can design platform services that integrate at that layerProficiency in Go, Python, or similar languages with production experience shipping services in cloud-native environmentsEffective cross-functional collaborator. You can align stakeholders, influence without authority, and translate complex technical trade-offs for technical and non-technical audiences alikeHands-on experience with artifact management, including distributed storage, caching, versioning, or multi-region artifact distribution (e.g. JFrog Artifactory, Cloudsmith, or custom-built 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 environmentsExperience building or extending CI and build infrastructure at scale, including GitHub Actions, Buildkite, Bazel, or similar build systemsDirect experience building agentic systems, including MCP servers, tool-augmented LLM workflows, and incorporating these capabilities into DevEx platform features with consistent value-add6+ years of software engineering experience with building production platforms, developer tooling, delivery infrastructure, or distributed storage systems
