About the role

Senior Software Engineer to design, build, and operate scalable, reliable web services in a distributed-systems environment, focusing on security products and services that protect customer data, enforce access decisions, and provide trustworthy building blocks for the CoreWeave platform.

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, 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.

Qualifications

  • 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.
