• Implementing networking layers and P2P (peer-to-peer) protocols
• Handling and managing large datasets with strict real-time performance requirements
• Optimizing software performance
• Solving technical challenges alongside top software engineers and research professionals
• Utilizing the latest tools and technologies
• Troubleshooting technical issues

Requirements:

• Proficient in implementing efficient algorithms and designing complex data structures
• Excellent programming skills, preferably in C#, Rust, or GO; proficiency in other tech stacks like Java or C++ will be considered
• Understanding of good software architecture principles
• Ability to write clean, testable, and maintainable code without over-engineering
• Entrepreneurial mindset with a willingness to take ownership and tackle problems
• Several years of experience in software development
• Strong background in computer science
• Keen interest in the inner workings of blockchains

While not necessary, deep knowledge in one of the following areas is highly desirable:

• Distributed networks (P2P)
• Performance and memory optimization
• Blockchain/EVM/TransactionPool/JSON RPC
• Complex data structures such as Patricia-Merkle/Verkle tries
• NoSQL Key Value databases like RocksDB
• Cryptography

Examples of Projects:

Our team has worked on various projects, including:

• Building an Ethereum client from scratch
• Implementing the Snap Sync protocol to enhance the speed of Ethereum node synchronization over the network
• The Merge - implementing and migrating from Proof of Work to Proof of Stake
• Performance improvements to an internal virtual machine (EVM)
• Enhancements to memory management
• Designing and implementing efficient and robust data stores and caching
• Libp2p implementation in C#

Perks and Benefits:
