Job summary

CoreWeave is hiring a Senior Software Engineer for Security Products to design, build, and operate scalable backend services in a distributed environment. You will contribute to security-critical building blocks, shape API contracts, and ensure reliability across on-premises and cloud integrations.

You will collaborate with product and security teams, focusing on secure, observable, and maintainable systems while delivering high-quality backend services in Go and other languages.

Qualifications

• Strong professional experience building and operating production backend services and improving 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.

Responsibilities

• 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 with metrics, logs, traces, dashboards, and actionable alerts.
• Participate in design reviews, code reviews, incident response, and post-incident improvements.
• Collaborate with Product, Security Engineering, Infrastructure, and partner teams for secure and usable platform capabilities.
• Design and support integrations with customers’ on-premises and cloud environments and with their security products.
• Work with customers and internal stakeholders to understand integration constraints and guide secure adoption.
