Frontend Engineer, DC infrastructure Tooling

CoreWeave•Sunnyvale, CA

7h•$143,000 - $210,000•Hybrid

About The Position

CoreWeave is building one of the world's largest AI-focused cloud infrastructure platforms. We're standing up new data centers at an extraordinary pace, and the complexity of planning, tracking, and orchestrating each build demands purpose-built tooling that doesn't exist today. We're forming a new team dedicated to building that tooling in-house. The goal: a high-performance internal platform that gives network engineers, fleet engineers, and operations teams the ability to plan, visualize, and manage massive amounts of physical infrastructure across dozens of sites. As the founding frontend engineer on this team, you'll own the UI layer for these tools. You'll work alongside backend engineers to build applications that handle the full scope of datacenter infrastructure: network switches, GPUs, servers, optical transceivers, PDUs, cooling systems, cable cutsheets, rack elevations, overheads, and more. Performance is non-negotiable. These tools need to render and interact with millions of objects per build without breaking a sweat. You'll make foundational technology decisions, establish the patterns and architecture that the team builds on, and have a direct hand in how quickly CoreWeave brings data centers online.

Requirements

Deep proficiency with TypeScript and React. You should be the kind of engineer who understands React's rendering model at a low level and can make deliberate decisions about when and how components re-render.
Demonstrated experience building interfaces that handle large, complex datasets with extreme performance requirements: virtualized rendering, canvas or WebGL-based visualization, efficient DOM management, or similar techniques.
Strong understanding of frontend architecture: component design, state management (particularly for complex, interconnected data models), data fetching and caching patterns, and build tooling.
Experience designing and consuming APIs with attention to type safety, pagination, caching, and error handling.
Track record of frontend performance optimization: bundle analysis, runtime profiling, and making data-heavy UIs feel fast under real load.
Genuine curiosity about (or direct experience with) physical datacenter infrastructure. The ideal candidate has a working understanding of servers, GPUs, network switches, optical transceivers, structured cabling, power distribution, and cooling. You don't need to be a network engineer, but you should be someone who finds this domain interesting and wants to understand how these systems relate and fit together.
Ability to work directly with infrastructure engineers (the end users of what you build) to understand their workflows, identify pain points, and translate complex operational processes into clean, usable interfaces.
Comfort working on a newly formed team where you'll be making early architectural decisions that compound over time. We need someone who is deliberate about tradeoffs and can move quickly without being reckless or sacrificing performance.
7+ years of professional frontend engineering experience, with meaningful senior-level ownership of production systems. For Staff level: demonstrated ability to make foundational architectural decisions and influence technical direction beyond your immediate team.
Strong communication skills. You'll be working across network engineering, fleet engineering, operations, and design. You need to explain technical decisions clearly and advocate for frontend concerns in cross-functional discussions.
Strong sense of ownership for the systems you build and the people who depend on them.

Nice To Haves

Direct experience with datacenter operations, infrastructure planning, or familiarity with DCIM tools like NetBox or Sunbird.
Experience working alongside backend teams writing Go, and comfort collaborating on API design across the stack.
Exposure to Infrastructure-as-Code, Kubernetes, or cloud platform concepts. You won't be directly deploying infrastructure, but understanding the ecosystem helps you build better tools for the engineers who do.
Experience with frontend observability, CI/CD pipelines, and modern build systems. We're building this team's practices from scratch, and having strong opinions about how to ship tooling matters.
Familiarity with authentication, authorization, and frontend security best practices for internal tooling.

Responsibilities

Extremely high-performance interfaces for visualizing and planning datacenter infrastructure, often rendering massive amounts of structured records (device inventories, cable plans, rack assignments, power allocations) with sub-second interaction and filtering.
Interactive planning tools for rack elevations, floor layouts, power distribution, and network topology that let engineers design, model, and validate builds before physical work begins.
Data-dense views and dashboards that serve as the authoritative source for build planning and asset tracking across CoreWeave's global footprint.
The frontend architecture from the ground up: component library, state management, data fetching patterns, and build tooling designed to scale with the team and product scope.
Tight integrations with backend APIs (likely gRPC, GraphQL, or REST), collaborating closely with backend engineers to shape API contracts that support the performance and data complexity the UI demands.
