At Halborn, we believe that elite blockchain security comes from a globally distributed team of white hat hackers, security engineers, and cryptocurrency specialists who operate with independence and precision. Our culture thrives on autonomy - team members make their own hours, work remotely from anywhere, and dive deep into complex adversarial challenges that span smart contracts, penetration testing, and vulnerability research. We ship continuous security assessments to production environments, not just reports, and we optimize for real impact over facetime.
Founded in 2019, Halborn has grown from a niche blockchain security firm into the trusted partner for the world's largest financial institutions and Web3 leaders including Solana, Coinbase, Circle, and Grayscale. Our engineers identify zero-day vulnerabilities affecting networks worth over $25 billion, and we've pioneered tools like the Blockchain Vulnerability Scoring System (BVSS). We're remote-first by design, with a 100+ person team across 20+ countries. We value agility - clients consistently praise our collaborative approach and willingness to pivot mid-project. If you're passionate about securing the future of digital assets and want to work alongside elite ethical hackers who've discovered critical exploits in Dogecoin, Litecoin, MetaMask, and more, this is where you belong.
