NuCypher (YC S16) | Engineering Lead | San Francisco, CA & REMOTE | FULL-TIME | VISA

NuCypher is hiring an engineering lead to help build a new open-source cryptosystem leveraging post-quantum cryptography. A successful candidate does not need to have prior experience in cryptography as they will work very closely with a cryptographer to build out the system. However, they should be a quick learner and comfortable around math (e.g. linear algebra, probability, number theory).

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 competitive compensation and a highly flexible working environment.

Responsibilities:

  * Design and build the core infrastructure of a new cryptographic system (alongside a cryptographer);
  * Lead the engineering side of the product;
  * Implement cryptographic primitives (including zero-knowledge proofs and fully homomorphic encryption) and write robust, security-first code that will run in high-risk, adversarial environments;
  * Contribute to research;
  * Improve engineering standards, tooling, and processes.

Competencies:

  * Proficient in a system programming language such as C or Rust (also open to those proficient in a functional programming language);
  * Competency in algorithms and low-level design;
  * Confidence working with multiple programming languages;
  * Comfortable around math;
  * Excellent communication skills and the ability to explain complex technical issues to a non-technical audience.

Bonus Points:

  * Math background and/or strong interest in math;
  * Background in compilers and/or optimization;
  * Familiarity with applied cryptography and advanced cryptographic concepts like lattice-based cryptography and zero-knowledge proofs;
  * Experience with designing and/or implementing large-scale distributed systems;
  * Any experience, professional or amateur, working in security engineering, appsec, or other information security roles is a plus (hackers are welcome!).

Please send your CV and a code sample you’re proud of to careers@nucypher.com

NuCypher is looking for generalist engineers to join us in building the future of decentralized privacy-preserving technologies, including proxy re-encryption and fully homomorphic encryption.

Responsibilities:

* Design, build, and maintain the core infrastructure powering our decentralized network;

* Review team members’ code to collaboratively identify bugs and correct security issues;

* Help establish threat models against our decentralized network and protocol.

Competencies:

* Deep knowledge of Python, Go, Javascript, Rust, or C;

* Familiarity with public-key cryptography and related cryptosystems, and the OpenSSL APIs;

* Familiarity with DevOps, CI/CD processes (CircleCI experience a plus!), git, automated testing (such as pytest), and other software development best practices;

* Verbal and written technical English.

Bonus Points:

* Experience with AWS deployment and management (IAM, ec2, s3, etc);

* Familiarity with applied cryptography literature/papers, and advanced cryptographic concepts like lattice-based cryptography and zero-knowledge proofs;

* Experience with designing and/or implementing large-scale distributed systems;

* Experience working with Ethereum, other blockchain ecosystems, or managing any decentralized network at scale (not necessarily blockchain-related) is a major plus;

* Deep understanding or knowledge of consensus networks and protocols, specifically as they relate to cryptocurrencies and other blockchain applications;

* Any experience, professional or amateur, working in security engineering, appsec, or other information security roles is a major plus (hackers are welcome!).
