Senior Cryptographic Engineer

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

• 5+ years of experience in software engineering.
• Be passionate about secure, reliable, well-documented and fast software.
• Flexible to work within an agile environment.
• Experience in implementing cryptographic constructions (down to the low-level mathematics) and familiarity with various common attacks.
• Deep understanding of applied cryptography and passion for creating effective and pragmatic cryptographic solutions to be integrated in complex systems and/or to conceive innovative products solving real world problems.
• Propose new meaningful approaches based on novel cryptography research available in academia.
• Experience in technical writing and documentation.
• Clear communication and articulation of abstract ideas.
• Enjoy guiding more junior developers and sharing your expertise. 
• Work gracefully with cross-functional teams within engineering, marketing, and other support teams to provide the best-in-class solutions.
• Autonomous, self motivated, and low ego. 

Preferred Qualifications

• Experience with system languages (C, C++, Go) and/or strongly typed programming (OCaml, Haskell, Rust).
• Theoretical and practical experience in state-of-the-art zero knowledge solutions such as Plonk (Plonky2, Plonky3, Halo2), STARKs, zk(E)VMs, recursive proof composition.
• Theoretical and practical experience in blockchain-based systems, with a particular focus on Ethereum and/or other EVM-based solutions.
• Experience with optimization of low-level mathematical operations, down to assembly level.
• Any experience with GPU/FPGA programming is welcomed.
