Backend Software Engineer building services for Qrypt's quantum security products, primarily in Rust. Work covers backend services and APIs that move quantum entropy and keys, the entropy-as-a-service platform, and appliance reliability at scale. Stack includes Rust, with some C++ and Python, on Linux.

Qrypt's mission is to protect the world's data and restore privacy. Qrypt hardens cybersecurity and future-proofs encryption against quantum attacks by eliminating key transmission. Qrypt's unique technology independently generates symmetric keys at multiple endpoints for critical workflows today. We are a passionate team of engineers, physicists, and cryptographers committed to transforming the way the world safeguards data and communications! 

Qrypt is looking for a Backend Software Engineer to build the services behind our quantum security products. You will write and ship backend software — primarily in Rust — that moves quantum entropy and keys, powers our entropy-as-a-service platform, and makes our appliances work reliably at scale. You will use AI-assisted development tooling as a core part of how you work, while owning the correctness and quality of everything you ship.
