About Legacy
Legacy is an easy-to-use, non-custodial Web3 wallet designed to protect digital assets through beneficiary protection and seamless DeFi access. Users can swap across chains, earn yield in one click, and safeguard wealth for the next generation.

Legacy is built by the team behind Decentralized Masters - a profitable $50M+ education and investment ecosystem with 4,000+ high-net-worth investors.

We’ve launched. Demand is strong. Now we need someone to own the post-acquisition customer journey and turn users into long-term, high-LTV subscribers.

We are building a portfolio of software products inside the Decentralized Masters ecosystem, including:
- Legacy Wallet - a non-custodial Web3 wallet with beneficiary protection and seamless DeFi access
- Trading Bot - automated crypto execution tools for serious investors
- Future fintech and investor infrastructure tools

We are now building the retention and lifecycle engine that will power long-term recurring revenue across all products.

About the Role





You will be the single person responsible for the security of a platform that tracks hundreds of millions in digital assets. That is the job. Everything else is secondary.

We need someone who breaks things for a living. Someone who looks at a login page and sees six attack vectors. Someone who reads a pull request and catches the injection vulnerability that two senior developers missed. Someone who lies awake thinking about the phishing campaign that hasn't been invented yet. If that sounds exhausting, this is not your role. If that sounds like Tuesday, keep reading.

Your primary responsibilities are security and quality assurance. You own penetration testing, vulnerability assessments, threat modeling, automated test frameworks, and CI quality gates across every product we ship. You also own infrastructure: AWS, CI/CD pipelines, monitoring, and incident response. And because we are a small, senior team, you will write productio
