• Proficiency in one or more systems languages (e.g., Go, Rust, C++) and familiarity with blockchain development frameworks
• Understanding of L1/L2 designs including rollups, state channels, or sidechains, plus awareness of consensus concepts such as PoS or Tendermint
• Interest in validating off-chain blockchain systems such as validators, oracles, bridge logic, and cross-chain interfaces
• Background in vulnerability assessment, security testing, fuzzing, or static analysis in blockchain contexts

🔹 Compensation & Benefits

• Competitive base salary, with performance-based bonuses
