Software Engineer – Peer-to-Peer (P2P)

About the role

This role is for a Software Engineer focused on building peer-to-peer (P2P) systems that enable decentralized search and networking at global scale. Based in South Africa, you will work with a team of engineers and researchers to turn advanced distributed concepts into production-ready solutions.

Key responsibilities

• Design, develop and maintain next-generation P2P infrastructure supporting decentralized search capabilities.
• Build resilient distributed systems without reliance on centralized indexes or traditional server-based architectures.
• Implement high-performance, highly concurrent networking solutions using Node.js and modern distributed technologies.
• Develop and optimise peer-to-peer network protocols, including connection management, reliability, encryption and NAT traversal.
• Apply knowledge of distributed databases, CRDTs and decentralized data structures to solve complex engineering challenges.
• Improve search technologies through information retrieval, ranking algorithms, indexing strategies and semantic search approaches.
• Collaborate with engineers and researchers to evaluate emerging technologies and translate ideas into robust software solutions.

Required profile

• Technically curious, hands-on engineer with strong experience in distributed systems and networking.
• Professional experience developing backend software with Node.js.
• Passion for peer-to-peer technologies, decentralized architectures and distributed computing.

Required skills

• Node.js
• Kademlia Distributed Hash Tables (DHT)
• Distributed databases
• Conflict-free Replicated Data Types (CRDTs)
• Encryption and NAT traversal
• Information retrieval, ranking algorithms, indexing and semantic search
