About the Role:

We’re partnered with a large-scale platform in the digital asset space where security is absolutely mission-critical. The team is responsible for protecting high-value assets while enabling millions of users to safely interact with blockchain-based systems.

They’re building out a specialized security group focused on securing everything from protocol integrations to wallet infrastructure, and need engineers who can operate deeply across crypto, distributed systems, and application security.

What You’ll Do:

• Identify gaps in crypto and infrastructure security, and drive cross-functional initiatives to address them
• Lead threat modeling, security reviews, and architecture assessments across blockchain integrations and backend systems
• Partner closely with engineering teams on secure design and implementation (including smart contract-related systems)
• Contribute to the development of internal security tooling and long-term roadmap
• Spot automation opportunities, build proofs of concept, and help productionize solutions
• Track and assess emerging changes in the ecosystem (new protocols, upgrades, cryptographic techniques)
• Share findings through internal write-ups, research, and knowledge sharing

Requirements:

• Strong working knowledge of blockchain systems (especially EVM ecosystems)
• 4+ years in security engineering across distributed systems, crypto, or infrastructure
• Experience threat modeling and securing complex backend systems
• Solid foundation in application security
• Familiarity with onchain primitives and workflows (smart contracts, bridges, DEXs, asset tracing, etc.)
• Awareness of emerging ecosystem trends and protocol-level changes
• Experience using modern AI-assisted development tools is a plus
• Comfortable operating in a fast-paced, highly cross-functional environment
• Prior mentorship or leadership experience is a plus
