Quantum Cryptography Engineer

Move Industries

About The Position

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. Our Mission 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. The Role We are seeking a Cryptography Engineer to lead our post-quantum security strategy and own the cryptographic foundations of the Movement Network. 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. 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. 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.

Requirements

Deep working knowledge of modern cryptography: signatures, KEMs, hash functions, ZK proofs, threshold schemes, MPC
Strong familiarity with the post-quantum landscape - lattice cryptography (LWE, Module-LWE, NTRU), hash-based signatures, code-based schemes, and the security/performance trade-offs between them
Track record of implementing cryptographic primitives in production code (Rust strongly preferred; C/C++ acceptable for systems-level work)
Ability to read an IACR paper on Friday and have a correct, constant-time prototype by Monday
Strong understanding of: Provable security, reduction proofs, and the gap between security models and real-world systems
Strong understanding of: Side channels, timing attacks, and constant-time implementation discipline
Strong understanding of: Consensus protocols and where cryptography lives inside them (signatures, randomness, accumulators, commitments)
Strong understanding of: Performance trade-offs: signature size, verification cost, batchability, aggregation
Bias toward shipping: papers are inputs, working code is the output
Care for long-term impact - you are designing primitives that may be securing user funds in 2040

Nice To Haves

PhD or equivalent research experience in cryptography, or a strong publication record at IACR venues (CRYPTO, EUROCRYPT, ASIACRYPT, TCC, PKC, RWC, CCS, S&P)
Contributions to widely-used cryptographic libraries (RustCrypto, arkworks, blst, dalek, libsodium, liboqs, OpenSSL)
Experience with NIST PQC submissions, IETF working groups, or standardization processes
Experience with formal verification of cryptographic code (HACL, fiat-crypto, Vale, jasmin)
Prior cryptography work on a major blockchain - Aptos, Sui, Ethereum, Solana, Cosmos - especially on randomness, threshold signatures, account abstraction, or zkLogin/Keyless
Experience implementing zkSNARKs, zkSTARKs, or post-quantum-friendly proof systems (FRI, lattice-based commitments)
Production deployment experience with hybrid PQ/classical cryptography (TLS 1.3 hybrid KEMs, signed updates, secure messaging)
Experience with hardware acceleration (AVX2/AVX-512, AArch64 SVE, GPU) for cryptographic workloads

Responsibilities

Lead the post-quantum cryptography roadmap: signatures, KEMs, threshold schemes, hybrid migration, and crypto-agility
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
Re-architect or hybridize core protocol primitives (Ed25519, BLS, Schnorr) with quantum-resistant analogues without regressing on latency, signature size, or throughput
Design crypto-agility into the protocol from day one: key rotation, algorithm negotiation, in-place migration paths that don’t require destructive hard forks
Build threshold, aggregate, and multi-signature schemes for validator consensus, including post-quantum-friendly variants
Own randomness: distributed key generation (DKG), verifiable random functions (VRFs), and post-quantum-secure leader election
Contribute to zero-knowledge primitives - account abstraction, privacy, succinct proofs - with a preference for post-quantum-friendly proof systems (STARKs, lattice-based SNARKs)
Audit cryptographic code, write formal specifications, and partner with verification efforts (Move Prover, EasyCrypt, F, Cryptol)
Engage with academic partners, NIST PQC standardization, and the broader cryptography community; publish where appropriate
Document threat models, security assumptions, and migration timelines so the rest of engineering can build confidently on top
