ROLE: Senior Cryptography Engineer
About the Role
We are seeking an exceptional Senior Cryptography Engineer to join our pioneering team as an Equity Co-Founder at the forefront of native blockchain execution. At Autheo we are building the platform that redefines decentralized computation delivering sub-microsecond execution speeds billions of transactions per second throughput and mathematically proven security against adversaries.
You will own the entire cryptographic stack that makes Autheo runs on post-quantum KEMs & signatures (ML-KEM ML-DSA SLH-DSA) fully homomorphic encryption (CKKS/TFHE) zk-SNARK/STARK circuits perfect forward secrecy transport enclave attestation and differential privacy all proven secure via formal methods and hardened to run at 50 B TPS with sub-10 μs per operation.
Key Responsibilities
Design and ship production FIPS 203206 (ML-KEM ML-DSA SLH-DSA) suite at <10 μs per op
Build hybrid PQ classical migration paths with zero-downtime key rotation
Implement CKKS/TFHE homomorphic execution for encrypted state and DePIN payloads
Ship zk-SNARK/STARK proof systems generating 15 ms proofs for L1 transitions and rollups
Harden SGX TrustZone enclaves with 1 TB EPC remote attestation and sealed memory
Deliver sub-15 μs post-quantum secure transport with perfect forward secrecy and replay protection
Embed ε0.5 differential privacy at consensus storage and VM layers
Formally verify IND-CCA2 EUF-CMA and side-channel resistance using TLA Coq EasyCrypt
Optimize crypto for AVX-512 GPU tensor cores achieving 200 GB/s DePIN encryption throughput
Research Innovation & Thought Leadership
Publish PQ FHE and zk breakthroughs at Crypto Eurocrypt Asiacrypt TCC
Keynote at Real World Crypto 2026 on 50 Billion Post-Quantum TPS with Formal Proofs
Requirements Must Have
8 years designing and shipping production cryptographic systems in Rust/C
Multiple mainnet deployments using lattice-based or zk primitives at scale
Proven formal verification of IND-CCA2/EUF-CMA security using Coq/EasyCrypt/F*
Hands-on post-quantum migration (NIST PQC finalist algorithms)
Deep expertise in side-channel resistant constant-time implementation
Nice to Have
Author or major contributor to NIST PQC submissions or IETF PQ standards
First-author papers at Crypto/Eurocrypt/TCC
Patents in FHE zk-SNARKs/STARKs or post-quantum signatures
First 90-Day Deliverables
Production PQ crypto library (<10 μs KEM/sign) live on mainnet
Full FHE execution of encrypted smart contracts at 25 μs latency
zk-proof system proving L1 state in 15 ms
Verified SGX/TrustZone enclave with 1 TB sealed memory
Formal proof suite covering 100 % of primitives
Open-source PQ FHE SDK 2000 stars
