Role Description We are seeking a deeply experienced cryptography engineer to lead security-critical work across ZODL’s protocol, specifications, and core infrastructure. This role is responsible for: - Reviewing and shaping the cryptographic foundations of Zcash-related software, ensuring correctness, privacy guarantees, and long-term protocol integrity. - Acting as a technical authority on cryptography and protocol design, working across specifications, implementations, and external collaborations. - Leading cryptographic reviews and audits of specifications and implementations across ZODL projects. - Performing security and privacy reviews of protocol changes, wallet flows, and cross-chain integrations. - Contributing to and reviewing Zcash protocol specifications (ZIPs) and internal design documents. - Identifying and mitigating privacy leaks, cryptographic weaknesses, and edge-case vulnerabilities. - Collaborating with engineers to ensure correct implementation of cryptographic primitives. - Participating in protocol design and evolution, including new features and upgrades. - Working with external researchers, auditors, and the broader Zcash ecosystem. - Guiding internal teams on best practices for cryptography and security architecture. - Responding to and helping coordinate security incidents and disclosures. The Core Engineer will report to the Head of Engineering. The Engineering Team now encompasses both Core and Zodl wallet development. Although this role will primarily involve the former, you will also be collaborating closely with developers working on the Zodl wallet. Qualifications - A commitment to our users’ privacy, and to the cypherpunk ethos of empowering freedom and autonomy by making secure, well-designed cryptography more widely accessible. - Deep expertise in applied cryptography. - Strong understanding of zero-knowledge proofs, especially in the context of Zcash (e.g. Sapling, Orchard). - Experience reviewing or designing cryptographic protocols. - Proven experience conducting security audits or formal reviews. - Strong ability to reason about privacy guarantees and threat models. - Experience working with technical specifications and protocol design docs. - Familiarity with Rust or ability to review Rust implementations. Requirements - Prior contributions to Zcash, ZIPs, or related ecosystems. - Experience with zk-SNARKs / Halo / PLONK-like systems. - Background in formal verification or high-assurance systems. - Public track record (papers, audits, open-source contributions). Key Traits - Paranoid (in a good way) about privacy leaks. - Extremely detail-oriented. - Comfortable saying “this is not safe to ship.” - Able to translate complex cryptography into actionable guidance.

Role Description We are seeking a pragmatic, high-output Rust engineer to build and maintain ZODL’s core infrastructure and wallet stack. This role focuses on shipping secure, reliable systems while collaborating closely with protocol and cryptography experts. - Build and maintain Zallet (our CLI wallet) and Zcash’s Rust-based core libraries - Implement protocol features based on existing specifications and guidance - Develop and maintain specifications to enhance, document, and support security analysis of the Zcash protocol, either led by ZODL or in collaboration with third-party developers - Develop wallet infrastructure and features - Improve performance, reliability, and developer ergonomics of core systems - Support downstream teams (e.g. Zodl mobile) with developing features, and investigating issues - Participate in code reviews, testing, and release processes - Respond to bugs and security issues with urgency Qualifications - Experience with Rust, and with developing secure and reliable code in modern programming languages similar to Rust, Swift, Kotlin, and Go - Experience building reliable, secure backend or systems-level software - Ability to work from technical specifications - Solid understanding of security fundamentals - Experience with testing, debugging, and performance optimization - Comfortable working in a fast-moving startup environment - Experience with cryptography libraries or blockchain systems - Familiarity with Zcash concepts - Experience with mobile-integrated backends or SDKs - Open-source contributions Requirements - Deep knowledge of cryptography is not required, but a willingness to learn and an appreciation for the importance of security are essential Key Traits - Pragmatic and delivery-focused - Strong ownership and accountability - Knows when to ask for review vs. push forward - Comfortable operating with incomplete information
