The Security Products organization builds the identity, authorization, cryptography, key management, and trust capabilities that help customers securely run sensitive workloads on CoreWeave. We work across product and infrastructure boundaries to deliver security-critical services that are dependable, standards-based, and simple to use.

We are looking for a Senior Software Engineer to design, build, and operate scalable, reliable web services in a distributed-systems environment. 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.

The ideal candidate combines strong software-engineering fundamentals with sound judgment around reliability, security boundaries, failure modes, and operational trade-offs. 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.

• 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
