Applied cryptographer_
Remote or New York · full-time
Break and fix cryptographic code in the wild, then teach the workflows to find what you found.
What you'll do
Audit cryptographic implementations as they actually ship — key handling, protocol state machines, randomness, signature and encryption misuse, padding and nonce mistakes — and turn each class of bug into a registry workflow that finds it. Own the cryptography benchmarks on the bench. Publish what you find, after disclosure.
What we look for
You have broken or fixed real cryptographic code, not just read about it. You read specifications and papers for pleasure and can tell a textbook weakness from an exploitable one — and prove which is which. You are at home in at least two of Rust, Go, C and Python, and in the libraries those languages use for cryptography.
What we offer
Your work is public under your name and run by everyone on the platform. The strongest models, the budget to run them, and a bench that tells you honestly whether your workflow works.
