1. R&D working culture
2. Designing and building distributed and fault-tolerant systems
3. An appreciation of scalable, high availability, and low latency architectures
4. Implementing networking layer and P2P protocols
5. Processing and management of large data sets with strict real-time performance requirements
6. Optimizing software performance
7. Opportunity to work with the top software engineers and research professionals to solve the toughest technical challenges
8. Working with the latest tools and technologies
9. Troubleshooting

Must Haves:

1. Ability to implement efficient algorithms and design complex data structures
2. Excellent programming skills, C# or Rust or GO preferred but will also consider other tech stacks (e.g. Java, C++)
3. An understanding of good software architecture
4. Ability to write clean, testable and maintainable code without over-engineering
5. An entrepreneurial nature, willing to take ownership and run toward problems
6. Several years of experience in software development
7. Strong computer science background
8. A fascination with the inner workings of blockchains

Nice to Haves:

1. Distributed networks (P2P)
2. Performance and memory optimisations
3. Blockchain / EVM / TransactionPool / JSON RPC
4. Complex data structures for example Patricia-Merkle/Verkle tries
5. NoSQL Key Values databases for example RocksDB
6. Cryptography

Examples of projects the team has worked on:

1. Building of Ethereum client from scratch
2. Implementation of Snap Sync protocol that improves the speed of Ethereum node synchronization over the network
3. The Merge - implementation, and migration from Proof of Work to Proof of Stake
4. Performance improvements to an internal virtual machine (EVM)
5. Improvements to memory management
6. Design and implementation of efficient and robust data stores and caching
7. Libp2p implementation in C#
