Senior Software Development Engineer - AWS Cryptography, Transport libraries
About The Position
The Transport Libraries team within AWS Cryptography builds and maintains open-source TLS and QUIC libraries (s2n-tls, s2n-quic) that protect data in transit across all of AWS. We're looking for an experienced software developer passionate about practical cryptography, open source, and building at scale. You'll work on post-quantum cryptography, leverage GenAI to accelerate secure transitions, and help ensure every byte moving in and out of the cloud is protected. If you're excited about implementing cryptography that secures millions of connections and want to contribute to some of the most security-critical open-source libraries in the industry, we'd love to talk.
