- - Deploy and operate services in AWS and other cloud providers.
- - Own problems end-to-end—from design through deployment to production support

- - A thoughtful communicator who values clarity and simplicity
- - Comfort working in a fast-paced, early-stage startup environment
- - Experience with event-driven architectures, message queues, or async workflows

- - Experience working in an early stage startup
- - Prior experience building security products or products for technical users
