Software Engineer P2P - Search Team

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Software Engineer P2P - Search Team based in Switzerland.

This is an opportunity to work on next-generation decentralized search technology within a highly distributed engineering <environment.You> will help build resilient, serverless search infrastructure based on true peer-to-peer architecture and decentralized data discovery.The role combines hands-on software engineering with opportunities to explore research-driven approaches to distributed systems and information <retrieval.You> will contribute to technologies capable of indexing and searching text, images, conversations, locations, and other forms of data without relying on a centralized index.The position is well suited to engineers who enjoy complex technical challenges and prefer turning innovative ideas into production-ready <systems.You> will work on high-performance, highly concurrent networking software and contribute to protocols designed for resilience, scalability, and decentralization.Strong curiosity, technical depth, and a builder mindset will be essential in shaping this evolving technology stack.

Accountabilities

• Design and develop next-generation peer-to-peer search infrastructure based on decentralized and serverless architectures.
• Build resilient distributed systems capable of operating without a centralized search index or traditional server infrastructure.
• Develop and optimize distributed indexing mechanisms and search architectures for different types of data, including text, images, chats, and locations.
• Contribute to peer-to-peer networking components, including connectivity, transport reliability, multiplexing, NAT traversal, and encryption.
• Design and implement high-performance, highly concurrent networking code with a focus on scalability, reliability, and efficiency.
• Work with distributed data structures, databases, CRDTs, and decentralized synchronization mechanisms.
• Research, evaluate, and implement approaches related to Kademlia DHTs, skip graphs, prefix hash trees, m-LIGHT, locality-sensitive hashing, and other distributed search techniques.
• Apply information retrieval principles such as recall, precision, ranking, lexical search, semantic search, and inverted indexes to decentralized search systems.
• Test, benchmark, evaluate, and optimize network protocols and distributed search components.
• Investigate complex technical problems, translate research findings into practical solutions, and maintain a strong bias toward implementation.
• Contribute to the evolution of the P2P technology stack, including components such as hyperdht, hyperswarm, hypercore, hyperbee, hyperdrive, and udx-native.
• Collaborate with a globally distributed engineering team to design robust solutions and continuously improve system performance and resilience.

Requirements
