Job description

About the Company

REMOTE - CET/ET

My client believes that a sound currency and functioning financial system should be basic human rights. Their mission is to help create an open, uncensorable financial system that is secure enough for billions of people to trust with their life savings. Traditional blockchain security reviews are a good start, but its not enough. That's why they provide protocols with state-of-the-art, incentive-aligned audit contests, bug bounties and smart contract coverage. And why they are putting so many resources behind AI security. They are the only security provider that includes a warranty after each audit. They are the leader in auditing, running more public audits than any other provider last year. The Ethereum Foundation, Aave, Optimism, Cosmos, MakerDAO (now Sky) and the biggest crypto teams in the world choose them for their security needs.

About the Role

We believe the blockchain security space is going to be fundamentally different in the next 6-24 months. Blockchain security is one of the areas of software that has experienced very little AI-related change in the last 2-3 years. We believe this is, in part, due to the novelty and complexity of blockchain exploits. As AI improves, we expect the blockchain security space to undergo massive change. We want to lead this change to disrupt our current business model. This is where we need your help. No one knows how effective AI can be in finding blockchain vulnerabilities. Few have put significant resources into this effort. Even fewer have worked with true AI and blockchain security experts on this problem. Our goal is to be the leader and pioneer in this area. We are looking for a senior Python developer with a strong track record shipping software products. This person has already proven themselves in production, brings a willingness to deep dive into the Solidity language and ecosystem, and works comfortably with LLMs in daily life. You have used LLMs in your workflow and have experimented with or even created AI products or applications. Take ownership of a core feature or process within our AI product, beginning with Solidity-focused workflows, and drive it end-to-end from design through production. We already has a rockstar team of developers and security researchers who can shore up your weaknesses in certain areas and ship a useful, production-ready application. And we are willing to invest deeply in your teams success, whatever it may require.

• Move quickly and get stuff done on a small, elite team that has already made a big impact in the crypto space
