Lead Engineer
NuCypher; San Francisco, CA (remote possible)

NuCypher is a cryptography company that builds privacy-preserving infrastructure and protocols. We are backed by Y Combinator and Polychain Capital.

A successful candidate will lead engineering for the new open-source cryptographic product from the ground up. They will work on problems at the forefront of cryptography and have a leadership role in design decisions of the system. As such, competency in algorithms and low-level design is a must. An interest in compilers and/or optimization would be nice to have.

Given the nature of an early stage product, a successful candidate should work in a fast and iterative style when it comes to prototyping. They will be be motivated by solving tough open-ended problems. Additionally, they should be highly comfortable working in a system programming language such as C or Rust (whether through work experience or side projects).

We offer extremely competitive compensation and a highly flexible working environment (remote-first, headquartered in San Francisco).
