Pinecone Tech Stack

Vector database platform for production AI applications

Software Development New York, NY 51–200 employees Founded 2019 Privately Held
pinecone.io LinkedIn

Pinecone operates a vector database built for retrieval-augmented generation (RAG) and semantic search at scale. The stack spans Rust, Go, and C++ for core performance, with Kafka/Kinesis/Pub/Sub for streaming ingestion and Kubernetes orchestration across AWS/GCP/Azure — a polyglot, infrastructure-heavy architecture suited to the latency and throughput demands of production vector workloads. Current hiring is engineering-focused at senior and staff levels, while active projects signal a shift from pure search toward agent-driven workflows and knowledge graphs, paired with adoption of Cursor and Model Context Protocol (MCP) for AI-assisted development.
