About The Job

The P2P Search team is building a next‑gen stack for resilient, decentralized search. We're serious about decentralization -- that means a truly peer‑to‑peer architecture with no centralized index. It's search without servers -- our technology empowers anyone to spin up a self‑organizing, unstoppable search engine for text, pics, chats, locations, or any data you can imagine.

We're seeking talented software engineers with a passion for P2P, an interest in research but a bias for building, and a deep understanding of some combination of the following:

• Kademlia DHT.
• Distributed indexing and the relevant research literature: skip graphs, prefix hash trees, m-LIGHT, locality sensitive hashing.
• Distributed databases and CRDTs.
• Networking for P2P: TCP/IP, transport‑layer connection orientation and reliability models, multiplexing, NAT traversal, encryption.
• Classical IR topics and search engine architecture: recall vs. precision, ranking algorithms, lexical vs. semantic search, inverted indices, etc.
• Network protocol testing, evaluation, and optimization.
• Writing high performance, highly concurrent networking code.
• The Holepunch stack: hyperdht, hyperswarm, hypercore, hyperbee, hyperdrive, udx-native
