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.
