Role Overview ID.me is seeking a Staff Software Engineer to join the Wallet – Authentication & Identity Proofing team. This team owns the core authentication and identity verification flows that millions of members rely on every day — from secure login and multi-factor authentication to passkeys, biometrics, and the end-to-end member experiences that establish trust and unlock access to government, healthcare, and commercial services. As a Staff Engineer, you will be a technical anchor for one of ID.me’s most critical and high-scale engineering domains. You will drive architecture decisions, lead complex cross-team initiatives, and raise the bar for engineering quality, security, and reliability. You’ll collaborate closely with product, security, and platform teams to shape the next generation of authentication and identity proofing at ID.me. This position will work from our Mountain View, CA office five days per week. Key Responsibilities Architect & Lead Authentication Systems: Design and evolve scalable, secure, and resilient authentication experiences, including MFA, passkeys (FIDO2/WebAuthn), biometric flows, push notification authentication, and OAuth2/OIDC-based login systems that serve tens of millions of members daily at peak volume. Drive Identity Proofing Excellence: Lead the technical design of end-to-end member-facing verification flows, including document-based identity proofing, face match, supervised verification, and trusted referee experiences — ensuring they meet NIST 800-63-3 IAL2/AAL2 standards with minimal friction. Technical Leadership & Mentorship: Serve as a technical anchor for the team — setting the standard for code quality, system design, and engineering best practices. Mentor senior and mid-level engineers through code reviews, architectural guidance, and pairing. Cross-Team Collaboration: Partner with Security, Platform, Identity Graph, Product, and Compliance teams to deliver cohesive features and integrations. Drive alignment on shared architectural decisions and multi-team initiatives that span authentication and identity verification. Reliability, Performance & Security: Own the availability and performance of authentication services at scale. Lead initiatives around observability, alert hygiene, capacity planning, and incident response for high-traffic, high-sensitivity systems. Compliance & Data Integrity: Champion compliance initiatives including data retention, compromised credential detection, biometric data governance, and privacy-preserving design patterns. Ensure authentication systems meet evolving legal and regulatory requirements. Roadmap Influence: Provide technical input into team roadmap planning. Identify engineering investments that improve developer velocity, system resilience, and member experience — and advocate for them with engineering leadership and product.
