About Holepunch
At Holepunch, we’re building a peer-to-peer development platform that lets you build apps that don’t require infrastructure. No servers whatsoever. Holepunch apps can be deployed to users directly from the machine you develop on, and scale effortlessly. Since servers are removed from the equation, users retain full control over the data they create, keeping things maximally private. The benefits of peer-to-peer are innumerable, and we envision a world where everything is peer-to-peer by default. We’ve started demonstrating what this future will look like with Keet, our P2P communications app.
Holepunch is built on a battle-hardened, Node.js-based technology stack we’ve built called Hypercore, which provides the basic machinery for establishing peer-to-peer connections and replicating data in a fashion similar to BitTorrent.
Currently looking for:
P2P Node.js Engineer (Remote)
We're big fans of Node.js — Holepunch is built on it. During this next growth phase, we could use your help to expand and strengthen our core P2P networking and storage primitives. Our P2P technology covers a wide surface area, so if the parts of this following tech profile fits you, we’d love to talk to you.
Requirements
Extensive knowledge of P2P protocols (Kademlia, BitTorrent, libp2p, hypercore)
Demonstrable experience optimizing network protocols for performance
Advanced JavaScript skills for implementing high-performance networking code
Deep understanding of UDP and TCP/IP networking, including NAT traversal techniques
Experience implementing custom binary protocols and serialization formats
Familiarity with cryptographic primitives for secure P2P communication
Experience with performance profiling and optimization of networked systems
Preferred Qualifications
5+ years experience building production P2P systems or distributed systems
Experience optimizing JavaScript for low-latency networking applications
Knowledge of V8 internals and JavaScript performance characteristics
Experience with libuv and asynchronous I/O in C
Contributions to open-source P2P projects or networking libraries
Experience building reliable systems on unreliable networks
Experience with Node.js native addons and bridging between JS and C
