We are seeking an exceptional Senior Platform Vector Database 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 planetary‑scale encrypted vector database that powers all RAG/KAG retrieval, agent memory, semantic search, and AI inference — delivering 0.4 μs encrypted ANN queries at 1 B+ QPS, 1 trillion+ vectors, full FHE + zk‑proof results, ε=0.5 differential privacy, and 80 % compression across 10,000+ DePIN shards.

• Ship production vector engine hitting 0.4 μs encrypted k‑NN/HNSW search at 1 B+ QPS
• Build DAG‑backed clustering and topological similarity search with zero redundancy
• Embed CKKS/BFV fully homomorphic encryption for exact search on encrypted embeddings
• Implement zk‑proof vector search returning 1–5 ms validity proofs for every result
• Deploy dynamic sharding of 1 trillion+ vectors across 10,000+ global nodes
• Integrate SGX/Trust Zone enclaves for 1 TB+ encrypted vector storage with remote attestation
• Ship 80 % lossless vector quantization/compression preserving post‑quantum security
• Deliver zero‑config vector SDKs (Rust/Go/Python) with built‑in encryption and proof generation
• Drive GPU‑native ANN graphs and AI‑driven index rebuild prediction

• Publish encrypted vector search and zk‑retrieval breakthroughs at NeurIPS, SIGIR, KDD, ICML
• Keynote at Vector
