Remote Vector DB Architect for GenAI & Semantic Search

Zoho; United States; Remote; USD 83,000 - 165,000; Part time

Job summary

Fyerx seeks an experienced Vector Database Specialist to design, configure, and optimize the storage infrastructure powering production-grade GenAI and semantic search applications.

The ideal candidate will architect highly scalable vector indexes, write high-throughput embedding ingestion pipelines, configure real-time hybrid search query spaces, and maintain low-latency vector infrastructure handling millions of embeddings.

Qualifications

• 2+ years actively scaling high-dimensional vector databases.
• Experience with vector index design and embeddings pipelines.
• Familiarity with hybrid search architectures.
• 4–8 years in data engineering or backend development.
• Certification in Vector DB or cloud data engineer preferred.

Responsibilities

• Design, deploy, and govern production vector databases (Pinecone, Milvus, Weaviate, Qdrant, or pgvector) to manage complex long-term memory structures for LLM applications.
• Build high-performance embedding ingestion pipelines, managing data chunking strategies, overlap controls, metadata schema extractions, and real-time upsert queues.
• Optimize high-dimensional vector search spaces, fine-tuning ANN graph parameters, HNSW metrics, IVF index lists, and scalar quantization bounds.
• Configure advanced hybrid search architectures, engineering unified retrieval flows combining vector lookups with BM25."
• Implement strict metadata filtering schemas, constructing optimized filter patterns to speed up context retrieval times and enforce dynamic domain isolation safety parameters.
• Monitor cluster metrics and resource optimization loops, tracking vector pod memory, index reconstruction latencies, QPS thresholds, and compute costs.
• Collaborate with AI and Data Engineering squads to evaluate text embedding models (e.g., OpenAI, Cohere, Hugging Face) and map vector sizing to downstream runtimes.
