Fractional Head of Security & Web3 Operations (Advisory / Retainer)

As a Fractional Head of Security & Web3 Operations at Financial Media Group, you serve as the technical bridge between leadership and external smart contract developers for a live, yield-bearing USDC protocol on the Base network. This is an advisory and governance role suited for a mid-to-senior blockchain developer, auditor, or security engineer seeking high-level exposure and consistent monthly compensation alongside your primary commitments. You are based in Singapore and available for occasional in-person working sessions.

What you'll do

• Review pull requests, technical specifications, and milestone deliverables from external development teams, then translate technical trade-offs into plain language for commercial leadership before sign-off
• Implement, document, and maintain strict multi-signature policies using Safe across hardware wallets, backup recovery protocols, and operational signing ceremonies
• Audit and tighten end-to-end access controls for deployment pipelines, domain registrar DNS, RPC nodes, and cloud infrastructure
• Verify smart contract deployments, contract upgrades, parameter adjustments, and BaseScan code before transaction execution
• Coordinate with external smart contract auditors, triage reported vulnerabilities, and maintain a lightweight emergency pause and recovery playbook

What you bring

• Direct, hands-on experience interacting with EVM contracts, Base and Optimism L2s, and DeFi primitives such as ERC-20, vaults, and liquidity pools. You understand Solidity code well enough to catch logic flaws and integration bugs
• Deep familiarity with institutional custody setups, including Safe multi-sig, Ledger, Trezor, air-gapped signing, permission revocation, and RPC manipulation defenses
• 3 to 6 years in software engineering, with at least 2 years focused on Web3 and smart contract security
• Ability to cut through developer jargon, assess risk clearly, and explain the commercial impact of technical decisions
• Knowledge of how production DeFi systems fail and pragmatic safeguarding practices for capital
• Based in Singapore and available for occasional in-person working sessions

What we offer

• Monthly advisory retainer based on an estimated 10 to 15 hours per month, with ad-hoc project bonuses for audit reviews and contract deployment sprints
