Senior Cryptographic Engineer

Horizen Labs



C++ C senior

Who We Are:

Our mission is to scale decentralized networks by significantly reducing the costs of zero-knowledge proofs. Founded in 2019, Horizen Labs is dedicated to building a more secure and equitable digital world at the heart of the decentralization revolution. Dedicated to elevating blockchain technology to unprecedented efficiency, we significantly reduce costs for proof verification without compromising security. Focusing on building next-gen, modular architecture, enhanced with composable zero-knowledge proofs, we are not just advancing the field - we are setting new benchmarks for performance, security and cost-effectiveness. At Horizen Labs, our people are our greatest asset, and we are creating a culture of empowered individuals who are eager to bring their ideas to life. We are looking for creative individuals to join our team of the best and brightest minds in the blockchain space. You will experience the exhilaration of joining a fast-growing and innovation-focused company. We believe diversity drives the innovation and engagement necessary to build a truly remarkable product. We operate on a hybrid model with a distributed global workforce who works in partnership with our satellite offices in New York City, NY and Milan, Italy. This allows us the flexibility to go to where the talent is. Are you ready to help us change the future with the next cutting-edge blockchain technology? Join us!

We are looking for a talented and motivated engineer who will contribute to building the cryptographic infrastructure of our Web 3.0-enabled blockchain ecosystem. You will be involved in the design and implementation of blockchain scaling solutions, primarily based on zero-knowledge cryptography, with the aim of dramatically reducing the costs that blockchain operators incur when deploying their products. Our international team works in a stimulating and innovative environment, where technical expertise and experience contribute to the development of cutting-edge blockchain technology. You will be joining a small, deeply driven team of highly technical minds in a culture of openness, pragmatism, and ownership of challenging problems that span software engineering, systems design, cryptography, and computing.

What You’ll Own

  • Design and implementation of blockchain-based cryptographic solutions leveraging modern cryptography (ZK, MPC, FHE).
  • Assume technical responsibility of novel systems while identifying areas for innovative research and development. 
  • Writing reusable, testable, and efficient code with a focus on best practices and security. 
  • Help shape the future of the company where you will be intimately involved in the strategic decision making process and immediately see the impact of your contributions.
  • Attend conferences and find opportunities in the on-chain ecosystem.

Skills and Qualifications
