Digital Asset Security Working Group Role Overview

We are seeking a Blockchain security specialist with deep expertise in distributed ledger technologies (DLTs) and application-layer security to lead the work in our Digital Asset Security Group. This is a hands-on, research-driven role: you will not only analyze and advise but also build proof-of-concepts, demonstrations, and exploit simulations to validate real-world risks.

You will operate as both defender and hunter – proactively identifying potential attack vectors, collaborating with cryptographers and our threat intelligence team and developing strategies and tooling to stay ahead of adversaries. This position bridges traditional cybersecurity with emerging blockchain and cryptographic paradigms – including future-proofing against quantum threats and others.

Key Responsibilities:

• Proactively hunt for threats across blockchain networks, smart contract ecosystems, and infrastructure components in collaboration with our intelligence team.
• Perform ongoing threat intelligence, attack surface mapping, and exploit simulation on Ethereum, Bitcoin, Solana etc.
• Design and execute proof-of-concepts and demonstrations for both discovered vulnerabilities and proposed mitigations.
• Identify and mitigate vulnerabilities in smart contracts, wallets, bridges, and node infrastructure.
• Conduct security assessments and code reviews across Solidity, Rust and off-chain components.
• Partner with engineering and DevOps to secure CI/CD pipelines, API gateways and validator nodes.
• Collaborate with cryptographers to help evaluate readiness for post-quantum cryptography (PQC) transitions.

• Advise on secure deployment patters, product launches, and security-by-design principles.

   

Qualifications Required:

• 5 to 10 years of experience in cybersecurity or blockchain security.
• Strong understanding of Ethereum, Solana and Bitcoin ecosystems (execution, consensus, infrastructure).
• Proven experience in smart contract auditing (Solidity, Rust, Anchor framework).
• Hands-on expertise in vulnerability research, exploits development, or PoC prototyping.

• Familiarity with threat hunting, attack simulation, and adversary emulation in blockchain environments.

   

Preferred:

• Familiarity with MEV threats, bridge exploits, flash loan attacks and cross-chain vulnerabilities.
• Experience with security tooling (Mythril, Slither, Echidna, Foundry, Halmos etc.)
• Knowledge of zk-SNARKS / zk-STARKs, MPC and threshold cryptography.
