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.
