Jay Deng is a founding engineer based in San Francisco with four years of hands-on experience building search and vector search systems at AWS and TikTok and now leading product at Tako. He’s a maintainer on the OpenSearch core repo, blending production-grade engineering with open-source stewardship—his GitHub motto, “OSS is the infinite game with my life,” reflects that commitment. Jay’s background spans search performance, storage, and resource access systems, giving him deep expertise in scalable, low-latency infrastructure. He moved quickly through roles at AWS from SDE I to Senior SDE working on OpenSearch Vector Search, demonstrating fast technical growth and ownership. A dual-degree graduate from Penn State in Computer Science and Economics, he combines rigorous engineering with an appreciation for system-level tradeoffs and product impact. Colleagues describe him as an engineer who prefers shipping robust, measurable improvements while investing in the longevity of community-driven tooling.
