  • The current version of the HOPR protocol is the bare minimal core that needs a wealth of interconnected components to make a privacy-respecting web3 stack a reality. You are expected to design and implement these layers with a growing team. Examples are overlay networks, packet retransmission, routing in a decentralized setting and dynamic resource allocation

  • Support and work with the community of developers, users, investors, enthusiasts who want to use HOPR

  • Theoretical knowledge and practical experience with the internet protocol stack and protocols, minimally: IP, TCP, UDP, (QUIC,) DNS, WebRTC

  • Familiarity with mixnet infrastructure and Tor along with existing limitations and issues

  • Familiarity with mechanisms and common issues, minimally: proxies, NAT, firewalls, packet loss & retransmission

  • Minimally 5 years hands-on development experience delivering Javascript applications in production settings

  • Zero knowledge protocols such as zk-SNARKs, Bulletproofs, zk-STARKs, zk-Rollups, Optimistic Rollups

  • Theoretical and practical knowledge of blockchain and crypto assets in general
