The Opportunity

We're building a new team to own and transform how Uphold approaches identity, authentication, and security across our global multi-asset platform. The Senior Backend Security and Identity Engineer is a foundational role where you'll shape the future of secure access for millions of users managing crypto, fiat, and precious metals.

You'll design and deliver state-of-the-art authentication systems (from passkeys to multi-factor challenges), strengthen compliance controls for regulated environments, and improve the user experience while improving security. This role combines deep technical expertise with leadership responsibilities - you'll architect critical systems, evaluate vendors, and eventually build and lead a team.

Implement modern authentication solutions including passkeys, WebAuthn, and advanced multi-factor authentication mechanisms (2FA, OTP, biometrics).
Build systems that enable continuous monitoring, compliance reporting, and forensic analysis for fraud prevention and regulatory teams.
Collaborate closely with Product, Fraud Prevention, Compliance, and Regulatory teams to ensure security solutions meet business and legal requirements.
Research, evaluate, and select third-party identity providers, security vendors, and authentication platforms.
Architect and implement integrations with external identity and security solutions.
Design systems that comply with financial regulations, ensuring strong customer authentication (SCA) and auditability.
Develop and maintain technical documentation, security policies, and architecture decision records.
Lead hiring, coaching, and development of team members as the team grows.
Other duties may be assigned as needed.

Proficient in authentication protocols and standards (OAuth2, OIDC, SAML, WebAuthn, FIDO2).
Experience building and scaling identity platforms at fintech companies or security-focused engineering roles at scale.
Understanding of risk-based authentication, fraud prevention patterns, and security controls in financial products.
