• Ability to simplify complex technical concepts for both technical and non-technical audiences.

• Excellent communication, client-facing, and project management skills.

Nice to haves, but not mandatory

• Familiarity with blockchain protocols such as Ethereum, Solana, or Layer-2 scaling networks.
