Fabric believes hardware determines the boundaries of humanity's collective creativity and imagination. We are building hardware for the next generation of cryptography because we believe in creating a more trustworthy world with secure, private computation at its core. Just as encryption and decryption enabled the Internet as we know it, this new paradigm of cryptographic algorithms, such as zero knowledge proofs, have even broader potential to revolutionize how trust, privacy, and identity work in our society. 

About the job
As a Cryptography Hardware Engineer at Fabric, you will play a pivotal role in shaping the future of modern cryptography systems and empowering our customers to build production systems securely. You will be involved in a variety of technical tasks related to ZKP protocols, framework improvement, and customer advisory, among other responsibilities. Your deep knowledge of cryptography, programming skills, and experience working with cryptocurrency or cryptographic products and LLVM will be highly valuable and necessary for the role.

What you'll be doing

    • Cryptography System Development: Utilize our framework to express modern cryptography systems, with a particular focus on Zero-Knowledge Proof (ZKP) protocols. Design and implement secure and efficient cryptographic solutions.
    • Product Improvements: Perform HW/SW co-design across the algorithms, the microarchitecture, and‬ the ISA‬.
    • Framework Enhancement: Continuously improve our existing framework and debugging tools based on your experience using them. Streamline the development process, optimize performance, and ensure robustness.
    • Technical Advisory: Advise customers on how to effectively use our system framework to build production systems, ensuring the security and integrity of their cryptographic implementations.
    • Research and Knowledge: Stay up to date on the latest advances in the field of cryptography, including emerging ZKP/FHE/PQC protocols and other relevant technologies. Incorporate these advancements into our products.

Qualifications and experience requirements

    • Qualifications and experience requirements
    • A Bachelor's, Master's, or Ph.D. degree in Computer Science, Electrical Engineering, Mathematics, or Computer Engineering.
    • Strong familiarity with the uses and implementations of Zero-Knowledge Proofs (ZKPs).
    • Experience implementing cryptographic algorithms in hardware, particularly‬ FPGAs.
    • Proficiency in programming languages such as Rust or Python, with a deep understanding of cryptography-related programming.
    • Previous experience working on a cryptography product.
    • An aptitude for problem-solving and a keen eye for details.
