Compensation & Growth Path This is a part time equity / token-based cofounder opportunity. You will receive equity in Launch Legends, Autheo, and the WFO Creator Network, along with token allocations in the Autheo blockchain. We have already completed an initial financing round to support infrastructure and marketing, and are currently in discussions with VCs and crypto investors to fund expansion and salaries. Salaried compensation is expected to begin within 4 to 5 months, following our node, token sales or funding.

ROLE: Senior Security Engineer – Privacy & ZKP

About the Role We are seeking an exceptional Senior Security Engineer – Privacy & ZKP 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 privacy stack that makes surveillance mathematically impossible — 1–5 ms zk-SNARK/STARK proofs at 50 B+ TPS, ε=0.5 differential privacy on all metadata, CKKS/TFHE homomorphic queries at 25 μs, secure MPC across 10,000+ nodes, and full GDPR/CCPA/HIPAA/HITRUST compliance baked into every layer.

Key Responsibilities • Ship production zk-SNARK + zk-STARK systems generating 1–5 ms proofs at 50 B+ TPS with GPU tensor-core acceleration • Build recursive + incremental proof composition for constant-size aggregation of millions of transactions • Implement global ε=0.5 differential privacy with tight privacy-budget accounting (δ<10⁻⁵) across DePIN and blockchain logs • Deploy CKKS/TFHE homomorphic pipelines enabling encrypted queries and analytics at 25 μs latency • Design secure MPC protocols for federated training and private set intersection on sensitive healthcare/DeFi data • Embed automated right-to-be-forgotten via zk-redaction while preserving chain integrity • Deliver formal privacy proofs (IND-CPA, RUP, DP) using EasyCrypt/Coq and automated CI verification • Build developer SDKs that make “private by default” zero-config for dApps

Research, Innovation & Thought Leadership • Publish privacy + zk breakthroughs at IEEE S&P, USENIX Security, PETS, CCS • Keynote at PETS 2026 / ZKProof 2026 on “50 Billion Private TPS with Formal Guarantees

Requirements – Must Have • 8+ years shipping production privacy systems (zk-SNARKs/STARKs, FHE, MPC, DP) • Multiple mainnet deployments with ≥10 B private transactions processed • Proven formal verification of privacy properties in Coq/EasyCrypt/F* • Hands-on GPU-accelerated proof generation and homomorphic computation • Experience passing SOC 2 Type II / HITRUST / HIPAA audits for privacy tech

Nice to Have • First-author papers at PETS, IEEE S&P, CCS, or ZKProof • Patents in recursive proofs, private smart contracts, or regulatory-compliant zk • Experience leading GDPR/CCPA compliance certifi
