Job Description
<h2><strong>About Move Industries</strong></h2><p style="min-height:1.5em">Move Industries is building the People’s Chain, a Move-based Layer 1 blockchain, and a diverse ecosystem that empowers talented builders to create the future of finance, infrastructure, and real-world value on chain. As a core contributor to the Movement Network, we combine deep protocol engineering with open community governance, returning blockchain to its roots by giving financial power, access and opportunity back to the people.</p><h2><br /><strong>Our Mission</strong></h2><p style="min-height:1.5em">Our mission is to fuel the next generation of secure, expressive, and high-performance blockchain applications through the Move programming language and scalable distributed systems. You will help unlock massive throughput, low latency, and resilience across consensus, data availability, and privacy - the invisible rails that make an open and decentralized future possible.<br /></p><h2><strong>The Role</strong></h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em">We are seeking a Cryptography Engineer to lead our post-quantum security strategy and own the cryptographic foundations of the Movement Network.</p></li><li><p style="min-height:1.5em">This is a research-meets-production role. You will design, analyze, and ship the primitives that secure consensus, accounts, randomness, and bridges - with a particular focus on making the network resilient to quantum adversaries. You will own the migration path from classical primitives (Ed25519, BLS, Schnorr) to post-quantum and hybrid schemes, and define the cryptographic posture of an L1 that is intended to outlive the cryptographically relevant quantum computer.</p></li><li><p style="min-height:1.5em">We approach this work with the seriousness it deserves. Bad cryptography fails silently, sometimes for years, and on a public chain those failures are irreversible. We are looking for someone who treats correctness, side channels, and proof artifacts as first-class deliverables - not afterthoughts.</p></li><li><p style="min-height:1.5em">This is not a research-only role, and not a pure-implementation role. You will read papers, write specifications, and ship code that runs on every node in the network.</p></li></ul><h2><strong>What You’ll Do</strong></h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em">Lead the post-quantum cryptography roadmap: signatures, KEMs, threshold schemes, hybrid migration, and crypto-agility</p></li><li><p style="min-height:1.5em">Design and implement cryptographic primitives in Rust - lattice-based (ML-KEM, ML-DSA / Dilithium), hash-based (SLH-DSA, XMSS, LMS), and hybrid constructions combining classical and PQ schemes</p></li><li><p style="min-height:1.5em">Re-architect or hybridize core protocol primitives (Ed25519, BLS, Schnorr) with quantum-resistant analogues without regressing on latency, signature size, or throughput</p></li><li><p style="min-height:1.5em">Design crypto-a
