About the Role
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.
What You'll Do
Protocol Analysis & Design
- 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.
System Security Re-architecture & Hardening
- Drive security-requirement-driven re-architecture and maintenance of existing software systems.
- Embed security assumptions at the architecture level, designing and implementing defense-in-depth for critical modules to reduce single points of failure and ambiguous trust boundaries.
Research, Audit & Response
- Track cutting-edge blockchain attack techniques and defenses, and turn research into shippable system improvements.
- Participate in or lead security audits of internal systems and open-source dependencies, driving remediation and architectural improvements.
Background & Experience
- Master's degree or above preferred in Computer Science, Cryptography, or Network/Cyber Security.
- New graduate or up to 2 years of work experience.
Core Technical Skills
- Development & architecture: Strong command of at least one systems-programming language among Java / Go / Rust / C++. Proficient in distributed systems design, concurrency models, and performance optimization.
- Security domain knowledge: Familiar with threat modeling, secure coding standards, penetration-testing mindset, and supply-chain security.
Key Soft Skills
- Security mindset & risk thinking: Operates on a "zero trust" principle by default and reasons systematically about attack surfaces.
- Analysis & abstraction: Translates complex, ambiguous security requirements into clear, verifiable technical architecture and module designs.
- Engineering craft & influence: Builds a security culture across the team through design docs, code reviews, and tech talks.
Preferred Qualifications
- Deep understanding of the full technical stack of at least one mainstream blockchain (networking, consensus, execution, storage). Strong grasp of smart contract security and common vulnerability patterns.
- Practical command of how public-key cryptography, hash functions, zero-knowledge proofs, and threshold signatures apply — and where their risks lie — in real systems.
