Cryptographic Engineer Bitcoin DeFi

## You will work closely with researchers, protocol designers, software architects, and QA teams to ensure cryptographic correctness, performance, and maintainability, with a strong emphasis on high-assurance coding and practical deployment. Collaborate with distributed teams across time zones, taking ownership of assigned tasks and delivering to agreed standards. Design and implement cryptographic constructions, such as digital signatures, zero-knowledge proofs, verifiable random functions (VRFs), commitment schemes, and accumulators. Develop and maintain cryptographic libraries, primarily using Rust and Haskell (with occasional use of C-with attention to safety, clarity, performance, and auditability. Translate academic research and formal specifications into reliable, well-structured production code. Participate in cryptographic design discussions, parameter tuning, and performance benchmarking. Analyse and validate protocol design to ensure security, via properties such as soundness, liveness, and resistance to practical attacks. Troubleshoot, debug, and optimise cryptographic code and its interaction with broader systems. Write and maintain clear documentation, including developer guides and internal design notes. Stay current with developments in cryptography and assess their relevance for ongoing or future projects. ## Who you are: Typically, a PhD in Computer Science, Cryptography, Mathematics, or a related field. Proven experience in academic publications. Practical experience in applied cryptographic engineering through academic research, industry work, or open-source contributions. Proven proficiency in Rust (and ideally some Haskell) for systems-level cryptographic development. Experience with version control systems, especially Git, in collaborative development environments. Exposure to cryptography for blockchain, distributed systems, or consensus mechanisms is a plus. Solid mathematical foundation in cryptography, number theory, finite fields, and probability. Ability to work independently in highly-complex cryptographic topics. • *The future of finance is here — whether you’re interested in blockchain, cryptocurrency, or remote web3 jobs, there’s a perfect role waiting for you.**
