P2P Networking Protocol Engineer

Logos is a social movement and decentralised technology stack built to revitalise civil society.

P2P networks are at the heart of decentralised technologies and libp2p has quickly gained popularity as the go to p2p stack.
We, the IFT P2P team, have successfully implemented and deployed a full fledged libp2p stack, which is now powering Logos, the Nimbus Ethereum 2 client, and the Status app .
Our implementation is written in Nim - an efficient, expressive and elegant programming language.
Besides developing nim-libp2p, we conduct applied P2P research and take part in the libp2p specification process.
Lately, we arefocusing heavily on the P2P Logos module. This module incorporates P2P protocols that extend beyond libp2p.

The role:

We are seeking a skilled P2P Networking Protocol Engineer to work on the implementation and refinement of P2P networking protocols.
Your focus will be on developping the Logos core P2P module, implementing P2P protocols, and advancing the nim-libp2p implementation by further architecting and developing its capabilities, adhering to existing specifications, and also improving and enhancing existing protocols.
Your responsibilities include collaborating across teams to address networking-specific needs, ensuring interoperability, scalability, and security in distributed systems.
You will play a critical role in researching and developing innovative solutions, pushing the boundaries of P2P networking technology to meet evolving demands effectively.

Key responsibilities:

• Implementing P2P networking protocols
• Implementing Logos core modules
• Further architecture and development of the nim-libp2p implementation
• Implement libp2p protocols according to existing specifications
• Research and development of new p2p protocols and primitives
• Working across teams to help with networking specific needs

You ideally will have:

• A passion for decentralisation, P2P and privacy-preserving technology
• Strong engineering background
• Experience with encryption and key exchange mechanisms
• Experience with low level/strongly typed languages (C/C++/Go/Rust or Java/C#)
• Experience building networking-heavy applications and P2P networking specifically
• Experience implementing with core networking protocols such as Websockets and/or Quic
• Familiar with P2P building blocks such as gossiping, routing and discovery (DHTs), and Nat traversal

Bonus points:

• Experience working remotely
• Experience working for an open source organization
• Previous experience with libp2p, preferably as a direct contributor to the codebase or specifications OR experience with other off-the-shelf networking stacks such as devp2p
• Experience with the Nim language

[Don’t worry if you don’t meet all of these criteria, we’d still love to hear from you anyway if you think you’d be a great fit for this role].

Interview Process:

• Intro call with the Talent team
• Interview with team member from the P2P team
• Pair programming interview with team member from the P2P team
• Interview with P2P team lead
