[Remote] Senior Software Engineer, Data Center Infrastructure Tooling

Note: The job is a remote job and is open to candidates in USA. CoreWeave is a leading provider of AI-focused cloud infrastructure solutions. They are seeking a Senior Software Engineer to design, build, and own the data layer, APIs, and services for their internal tooling, aimed at managing complex data center infrastructure across multiple sites.ResponsibilitiesData 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 scaleHigh-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 datasetsThe backend architecture from the ground up: service structure, data access patterns, caching strategy, and API contracts designed to scale with the team and product scopeIntegrations with internal/external systems and data sources that feed infrastructure planning, ensuring the platform reflects real-world state and planned builds accuratelyDeployment and operational infrastructure for the services you build, including Kubernetes manifests, CI/CD pipelines, observability, and reliability practicesSkillsStrong proficiency in Go. You should be comfortable writing performant, well-structured services and have opinions about how to organize a Go codebase as it growsDeep 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 rowsExperience 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 consumeProven 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 areFamiliarity with authentication, authorization, and backend security best practices for internal toolingExperience owning deployment and operations for the services you build: Kubernetes, CI/CD pipelines, monitoring, alerting, and incident response. You ship it, you run itGenuine 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 coolingStrong 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 evolvingAbility 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 APIsComfort 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 performance5+ years of professional backend engineering experience, with meaningful senior-level ownership of production systems and the data layers behind themStrong 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 discussionsStrong sense of ownership for the systems you build and the people who depend on themDirect experience with datacenter operations, infrastructure planning, or familiarity with DCIM tools like NetBox, Infrahub or SunbirdExperience with CockroachDB specifically, including its distributed SQL model and operational characteristicsExperience 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 workflowsExperience with event-driven architectures, change data capture, or audit logging for compliance-sensitive systemsBenefitsMedical, dental, and vision insurance - 100% paid for by CoreWeaveCompany-paid Life InsuranceVoluntary supplemental life insuranceShort and long-term disability insuranceFlexible Spending AccountHealth Savings AccountTuition ReimbursementAbility to Participate in Employee Stock Purchase Program (ESPP)Mental Wellness Benefits through Spring HealthFamily-Forming support provided by CarrotPaid Parental LeaveFlexible, full-service childcare support with Kinside401(k) with a generous employer matchFlexible PTOCatered lunch each day in our office and data center locationsA casual work environmentA work culture focused on innovative disruptionRemote work may be considered for candidates located more than 30 miles from an office, based on role requirements for specialized skill setsCompany OverviewCoreWeave provides cloud infrastructure services designed to support artificial intelligence and high-performance computing workloads.
