Lead Security Engineer – Identity & Authentication
Build the future of secure finance. Protect millions. Own the identity layer of Web3.
We’re assembling a foundational team to redefine identity, authentication, and security across a global financial platform operating at the intersection of crypto, payments, and regulated infrastructure.
This is not just another engineering role, this is your chance to own and architect mission-critical systems that secure millions of users managing digital and traditional assets worldwide.
Responsibilities:
• Architect and scale next-gen identity & authentication systems (passkeys, WebAuthn, MFA, biometrics)
• Build secure-by-design infrastructure that balances UX with strict regulatory requirements
• Design systems for fraud detection, compliance, and forensic visibility
• Own integrations with identity providers, security vendors, and fintech ecosystems
• Shape authentication strategies in regulated environments (SCA, KYC/AML, PSD2)
• Play a key role in building and mentoring a high-performance team
Requirements:
• Engineers from crypto, fintech, or payments backgrounds who’ve worked at scale
• Strong backend expertise in Node.js (TypeScript/JavaScript) or Golang
• Deep understanding of OAuth2, OIDC, SAML, WebAuthn, FIDO2
• Experience designing secure, auditable systems in regulated environments
• Exposure to fraud prevention, risk-based authentication, and compliance frameworks
• A builder mindset—you’re excited to own systems end-to-end and influence strategy
Why This Role Stands Out
• Own one of the most critical layers in modern financial systems: identity
• Work on cutting-edge authentication tech (passkeys, adaptive auth, biometrics)
• Operate in a high-scale, multi-asset environment (crypto + fiat + beyond)
• Be part of a company pushing on-chain finance into the mainstream
• Opportunity to build a team from the ground up
If you care about security, scale, and shaping the future of financial access—this is your role.
