Senior Software Engineer, IAM

What You’ll Do

As a Senior Software Engineer on the Identity & Access Management (IAM) team, you will play a key role in designing, building, scaling, and maintaining CoreWeave’s rapidly expanding IAM platform. You will leverage your experience in distributed systems to design, extend, and harden a platform that secures our high-performance cloud infrastructure. You’ll be working at the intersection of design, developer experience, and platform architecture to help scale our services to the next order of magnitude. Here are just a few of the interesting and exciting things you’ll be doing:

• Architect and build high-scale, low-latency distributed systems that power CoreWeave’s identity, authentication and authorization services
• Design and implement customer-facing and internal APIs and backend services that underpin our IAM platform
• Optimize system performance to ensure that services remain highly available and performant under unpredictable load patterns
• Collaborate cross-functionally with stakeholders across the business, including product managers, designers and TPMs, to shape the team’s strategy and roadmap
• Drive operational excellence by participating in on-call rotations and building automated tooling for monitoring, alerting, and incident response
• Demonstrate and shape best-practices in software engineering by embracing AI for development, insisting on maintainable and testable code, and participating in thorough code reviews
• Work with incredible people in a supportive, iterative, high-trust, agile environment

Who You Are

• Experience: Minimum of 5 years of professional experience developing, operating and maintaining backend services in a production environment
• Programming: Strong proficiency developing software in one or more of our preferred languages (Go, TypeScript, Python)

• Observability: Fluency with best practices in observability (logging, metrics, dashboards, alerting)
• Database design: Solid understanding of relational databases, schema design, and SQL
• Testing and quality: Strong commitment to automated testing (unit, integration, and E2E) and CI/CD pipelines
• Ownership: Demonstrated ownership of code quality, performance, and maintainability from development through production
• Security: Experience with authentication, authorization and security best practices
• Problem solving: A proven track record of debugging complex performance bottlenecks and distributed system failures in a production environment
