ZK Proof Engineer

About Us Axiom is using zero-knowledge proofs to enable new types of verifiable and private software applications, starting with crypto and fintech. We are a small but incredibly strong team backed by the best investors in crypto . We’re looking for exceptional people who are excited to work on challenging and impactful problems in a fast-paced environment. Our office is in NYC and working in person in NY is our strong preference, but we're open to remote candidates as well. We recently released OpenVM , a performant and modular zkVM framework built for customization and extensibility. OpenVM allows developers to verify the correct execution of arbitrary computer programs in a flexible and performant way. We are building ZK-enabled products using OpenVM and supporting teams building on OpenVM. The Role We are looking for a ZK Proof Engineer who will implement and optimize cutting-edge cryptographic code for zero-knowledge proof generation. You will be responsible for building systems to interface between low-level computer systems like the RISC-V ISA, compiler frameworks like LLVM, and database backends and connecting them with cutting-edge zero-knowledge proof systems. The role will involve both optimizing ZK provers and implementing novel ZK circuits. Your work will require making design choices to enable rapid development of secure and efficient systems. We are looking for someone with strong engineering design skills, the ability to work across the stack, and a security mindset. We also value the ability to make pragmatic technology choices which empower our small team without adding too much overhead. Who you are • You have a strong background in math/cryptography, or strong problem-solving skills and interest in zero-knowledge proofs. • You have proficiency in Rust, C/C++, or a similarly performant backend language. We work primarily in Rust. • You are extremely detail oriented and have a security mindset. • You’ve worked on challenging software projects and have an eye for performance. • You’re a clear communicator and value collaboration. • You have a strong bias towards action. • You have an extremely strong work ethic. Bonuses • You have experience with compiler frameworks like LLVM or MLIR. • You've worked with aspects of low level computer architecture like RISC-V or programmed FGPAs or other custom hardware. • You have experience with database backends, including experience with query planning or low level query engines. • You've done research in mathematics, theoretical computer science, or theoretical physics. • You have experience with low-level details of Ethereum We welcome diverse backgrounds. Some non-traditional profiles that may be a good fit include high-frequency trading, math/physics/CS academia, and hardware engineering. Why join us • You’ll be one of the earliest employees with ownership to make key technical/product decisions. • You’ll be working on groundbreaking tech that has the potential to be a key piece of infrastructure for the crypto industry. • You’ll receive a competitive salary with equity. • You will work with and receive mentorship from an exceptional team. Our Team Our founders Yi Sun and Jonathan Wang met while studying math at Harvard and have been working on ZK since 2021. Together, they wrote some of the most performant ZK circuits for elliptic curve cryptography and Ethereum data reads before starting Axiom. Before Axiom, Yi was a professor at UChicago Statistics and did a math PhD at MIT. He was previously an advisor for Gauntlet and worked at an HFT startup from inception to profitable trading. Jonathan published number theory research in top math journals and did a math PhD at UChicago. The rest of our small but incredibly strong team includes alums of
