ABOUT THIS ROLE 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, and other infra teams the ability to plan, visualize, and manage massive amounts of infrastructure across hundreds of sites. As a senior backend engineer on this team, you'll help design, build, and own the data layer, APIs, and services that power these tools.  The goal is to build bespoke software to model our infrastructure at both a physical and logical level to drive planning, coordination, automation, of some of the most advanced AI datacenters.   The team will also include frontend engineers that you will need to work closely to bring rich user experiences built on top of your backends.. You'll also own how these services are deployed and run in production including scaling, redundancy and monitoring . WHAT YOU'LL BUILD * Data models and APIs that capture the complexity of datacenter infrastructure: devices, connectivity, cabling, power, cooling, and spatial relationships across racks, rows, and floors. The schema needs to be expressive enough to model reality and performant enough to query at scale. * High-throughput API services in Go (gRPC, GraphQL, and/or REST) that support the data density and interaction speed the frontend demands, including complex filtering, aggregation, and bulk operations across large datasets. * The backend architecture from the ground up: service structure, data access patterns, caching strategy, and API contracts designed to scale with the team and product scope. * Integrations with internal/external systems and data sources that feed infrastructure planning, ensuring the platform reflects real-world state and planned builds accurately. * Deployment and operational infrastructure for the services you build, including Kubernetes manifests, CI/CD pipelines, observability, and reliability practices. WHAT WE'RE LOOKING FOR CORE TECHNICAL SKILLS * Strong proficiency in Go. You should be comfortable writing performant, well-structured services and have opinions about how to organize a Go codebase as it grows. * Deep experience with relational databases, specifically PostgreSQL and CockroachDB. You should understand query planning, indexing strategies, schema design for complex relational data, and how to keep queries performant as data grows to millions of rows. * Experience designing and building APIs (gRPC, GraphQL, and REST) with attention to type safety, pagination, caching, filtering, and error handling. You'll be shaping API contracts directly with the frontend engineer, so you need to understand what makes an API pleasant and performant to consume. * Proven experience of performance optimization on the backend: query optimization, connection pooling, caching layers, profiling under load, and understanding where bottlenecks actually live rather than where you assume they are. FAMILIARITY WITH AUTHENTICATION, AUTHORIZATION, AND BACKEND SECURITY BEST PRACTICES FOR INTERNAL TOOLING. * Experience owning deployment and operations for the services you build: Kubernetes, CI/CD pipelines, monitoring, alerting, and incident response. You ship it, you run it. DOMAIN & PROBLEM-SOLVING * 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. * Strong data modeling instincts. The hardest problem on this team is capturing the real-world complexity of datacenter infrastructure in a schema that's both accurate and capable of evolving. * Ability to work directly with infrastructure engineers (the end users of what you build) to understand their workflows, identify pain points, and translate messy real-world processes into clean data models and APIs. * 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. EXPERIENCE & LEADERSHIP * Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field. * 5+ years of professional backend engineering experience, with meaningful senior-level ownership of production systems and the data layers behind them. * Strong communication skills. You'll be working across network engineering, fleet engineering, operations, frontend, and design. You need to clearly explain technical decisions and advocate for backend considerations in cross-functional discussions. * Strong sense of ownership for the systems you build and the people who depend on them. NICE TO HAVE * Direct experience with datacenter operations, infrastructure planning, or familiarity with DCIM tools like NetBox, Infrahub or Sunbird. * Experience with CockroachDB specifically, including its distributed SQL model and operational characteristics. * Experience building systems that handle complex graph-like or hierarchical relational data (asset trees, network topologies, dependency graphs). * Exposure to Infrastructure-as-Code, Terraform, or GitOps workflows. * Experience with event-driven architectures, change data capture, or audit logging for compliance-sensitive systems. WHY THIS ROLE IS DIFFERENT This isn't building another REST API in front of a simple CRUD database. We are building bespoke software which will be critical to the success of  building  some of the largest AI-focused data centers in the world.  The data is complex, the relationships are real, and the performance bar is high. If you've been looking for backend work where the data modeling is genuinely hard and the impact is tangible, this is it. WHY COREWEAVE? At CoreWeave, we work hard, have fun, and move fast!  We’re in an exciting stage of hyper-growth that you will not want to miss out on. We’re not afraid of a little chaos, and we’re constantly learning.
