Security Engineer
DevOps Security Engineer responsible for securing and scaling the Legacy Web3 wallet platform, managing CI/CD pipelines, infrastructure as code, and cloud operations on AWS to ensure robust, compliant, and high-availability services for a high-value user base.
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.
About the Software Division
We are building a portfolio of software products inside the Decentralized Masters ecosystem, including:
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 production code when security and QA responsibilities are covered. You are not a consultant or a checkbox auditor. You are an engineer who ships, and whose code happens to make everything else harder to break.
The ideal candidate has spent time at major product-driven fintech and crypto companies where a single security failure can destroy user trust overnight.
