Senior Engineer, CoreWeave

• The ideal candidate combines strong software-engineering fundamentals with sound judgment around reliability, security boundaries, failure modes, and operational trade-offs
• Strong professional experience building and operating production backend services and improving their reliability, performance, and maintainability.
• Experience designing and implementing RESTful and/or gRPC APIs
• Deep understanding of distributed-systems principles, including consistency, concurrency, fault tolerance, networking, and service-to-service communication
• Fluency in Go, Java, C++ or Python; willingness to work primarily in Go
• Experience with relational or distributed data stores, asynchronous processing, and service integration patterns
• Strong testing practices, including unit, integration, contract, load, and failure-mode testing as appropriate
• Ability to communicate technical decisions clearly in design documents, reviews, and cross-functional discussions
• Sound judgment when working with sensitive data, trust boundaries, authorization decisions, and security-sensitive failure modes
• This position requires access to export controlled information. To conform to U.S. Government export regulations applicable to that information, applicant must either be (A) a U.S. person, defined as a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (green card holder), (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, (B) eligible to access the export controlled information without a required export authorization, or (C) eligible and reasonably likely to obtain the required export authorization from the applicable U.S. government agency. CoreWeave may, for legitimate business reasons, decline to pursue any export licensing process

You will work on foundational security products and services that protect customer data, enforce access decisions, and provide trustworthy building blocks for the CoreWeave platform
• This role is a strong fit for an engineer who enjoys solving complex backend problems end to end, from API and service design through implementation, testing, deployment, observability, and production operations. You will work closely with engineers, product managers, security specialists, and infrastructure teams to turn ambiguous requirements into secure, maintainable systems
• You will also help integrate CoreWeave security services with customers’ on-premises and cloud environments, including the identity, key-management, and security products they already use. You will have meaningful ownership of technical direction and delivery while helping raise the engineering bar across the team
• Design and implement scalable, reliable backend services using REST and/or gRPC APIs
• Define clear API contracts, service boundaries, data models, and integration patterns
• Own services through their full lifecycle: architecture, implementation, testing, deployment, observability, on-call support, and continuous improvement
• Improve service reliability through effective error handling, retries, timeouts, idempotency, back-pressure, capacity planning, and graceful degradation
• Establish and use service observability, including metrics, logs, traces, dashboards, and actionable alerts to understand system health and customer impact
• Participate in design reviews, code reviews, incident response, and post-incident improvements
• Collaborate with Product, Security Engineering, Infrastructure, and partner teams to deliver secure and usable platform capabilities
• Design and support integrations with customers’ on-premises and cloud environments and with their security products, such as identity providers, key-management services, HSMs, SIEMs, and policy or access-control systems
• Work with customers and internal stakeholders to understand integration constraints, define reliable contracts, and guide secure adoption across heterogeneous environments
• Make pragmatic trade-offs between near-term delivery, long-term maintainability, performance, and operational risk
• Mentor engineers and contribute to a culture of technical excellence, ownership, and continuous learning
• In your first three months, you will develop a deep understanding of the team’s systems and customers, and contribute to production services. You will take ownership of meaningful technical problems and improve the clarity, reliability, and operational readiness of the services you support
• Over time, you will deliver secure and dependable capabilities, influence architecture beyond your immediate area, improve API and service reliability, and help the team scale its engineering practices as the Security Products portfolio grows
• Build foundational security capabilities for an AI-native cloud platform
• Solve challenging problems at the intersection of security, distributed systems, cloud infrastructure, and customer experience
• Work on services where correctness, reliability, and thoughtful security design matter every day
