Senior Backend Software Engineer leading design and development of backend services and APIs at Qrypt, primarily in Rust. Responsibilities include end-to-end ownership of backend architecture, reliability, and performance, plus mentoring and code review standards. Work supports quantum entropy and key delivery, the entropy-as-a-service platform, and appliances, with C++ and Python also used.

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.
