Graduate Hiring - Software Systems Design Engineer — Blockchain Security & Protocol

We're hiring a new‑graduate Software Systems Design Engineer focused on blockchain security and protocol design. You'll work at the intersection of cryptography, distributed systems, and adversarial security — redesigning and hardening wallet and core systems against protocol‑ and architecture‑level threats. This is a builder’s role for someone who thinks like an attacker and designs like an engineer.

• Analyze and evaluate how mainstream blockchain protocols work under the hood (Ethereum/EVM, Cosmos SDK, Substrate, Solana, etc.), and redesign wallet systems grounded in secure cryptographic mechanisms.
• Develop hardening and mitigation plans for the wallet system against known protocol‑level vulnerabilities and emerging risks.

• Drive security‑requirement‑driven re‑architecture and maintenance of existing softwa...
