- 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, xhqgsiq 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
