About The Position

We are seeking an exceptional Senior Platform Blockchain 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 core Layer 0 / Layer 1 blockchain stack: consensus, distributed ledger, dynamic sharding, cross-chain bridges, and DePIN integration – pushing beyond 50B+ TPS global throughput with sub-millisecond finality and full resistance to nation-state attacks, while enabling seamless interoperability with Ethereum, Solana, Polkadot, Cosmos and 20+ ecosystems.

Requirements

8+ years building production Layer 0 / Layer 1 blockchains in Rust and/or Go
Multiple mainnet launches with ≥10M TPS real-world throughput
Deep expertise in DAGs, BFT variants (Tendermint, HotStuff, Narwhal/Bullshark), sharding, and formal verification (TLA+, Coq)
Hands-on post-quantum cryptography integration into consensus
Proven track record shipping cross-chain interoperability (IBC, XCM, or equivalent) at scale

Nice To Haves

Former core contributor to Cosmos SDK, Substrate, Solana, Aptos, Sui, or Avalanche
First-author papers at top distributed systems or cryptography venues
Patents in consensus, sharding, or post-quantum blockchain primitives

Responsibilities

Architect and ship next-gen DAG + BFT hybrid consensus achieving 50B+ TPS and <500 μs probabilistic finality
Design dynamic sharding system scaling linearly across 10,000+ validator nodes with zero-downtime re-sharding
Build temporal weighting, verification pools, and entropy-based leader selection that eliminate Sybil and grinding attacks
Implement tuple-based state model and n-tier execution layers for unlimited horizontal scaling
Embed NIST FIPS 203–206 post-quantum cryptography (ML-KEM, ML-DSA, SLH-DSA) directly into consensus and networking
Deliver production cross-chain bridges supporting 5M+ TPS asset transfers and message passing
Formally verify liveness, safety, and double-spend resistance using TLA+ / Apalache
Drive open-source SDKs and tooling that become the default for sovereign chain deployment
Publish novel consensus and sharding breakthroughs at Devcon, Consensus, SBC, ICDCS
Keynote at Devcon 2026 on “50 Billion TPS Layer 0 at Sub-Millisecond Finality”
