Lead Security Engineer – Identity & Authentication

Work from home Full-time role Hiring

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
