Senior Software Engineer (SDE-IV) - Wallet - Authentication

Location: Mountain View, CA (Onsite 5 days per week)
Role Overview

ID.me is seeking a Senior Software Engineer (SDE-IV) to join the Wallet - Authentication team, where we build the core sign-in, registration, and account management experiences that over 140 million members rely on to access the ID.me identity wallet.

Authentication is the front door to ID.me - every member journey begins with creating, signing into, or managing their Wallet. Our team owns sign-in, registration, MFA, account recovery, password reset, and MyWallet, ensuring members can securely access their verified identity across 20 federal agencies, 44 state governments, 66 healthcare organizations, and hundreds of consumer brands.

As a Senior Software Engineer, you will own significant pieces of our authentication stack end-to-end - independently driving medium-to-large features and systems from ambiguous problem definition through production, and serving as a subject-matter expert that other engineers and teams rely on. You'll set technical direction for the areas you own, mentor and unblock teammates, and take accountability for both the engineering health and business outcomes of the systems in your sphere. Your work will sit at the intersection of identity, security, and consumer experience, directly shaping how millions of people prove and access who they are online.

This position will work from our Mountain View, CA office five days per week.
Key Responsibilities

• Own & Ship Authentication Features: Build, maintain, and improve the ID.me Wallet authentication experience - sign-in, registration, MFA, account recovery, password reset, and MyWallet. Take loosely defined problems, clarify requirements with stakeholders, create a plan, and independently drive medium-to-large features end-to-end from definition through deployment and post-launch evaluation - delivering well-tested, production-ready results with minimal oversight, and setting technical direction for the areas you own.
• Security, Risk & Production Reliability: Own and evolve the team's real-time risk engine and its integration across authentication flows - detecting and mitigating credential attacks, account takeover, and abuse while preserving a low-friction experience for legitimate members. Apply security best practices as a first-class concern in every feature you ship. Take accountability for the production health of these systems - participating in the on-call rotation, leading incident response and post-mortems, and driving improvements to reliability and observability across the team's services.
• Code Quality & Technical Leadership: Write high-quality, maintainable code with strong test coverage, following team best practices around code reviews, CI/CD, and documentation. Raise the bar for engineering excellence across the team, and mentor and unblock other engineers through pairing, code review, and knowledge sharing - creating team redundancy on the systems you own. Improve the health of the codebase by identifying and addressing technical debt and strengthening shared components.
• Third-Party & Internal Integrations: Integrate with MFA providers, email/SMS delivery services, internal identity services, and downstream relying parties. Proactively raise issues or opportunities discovered during integration work.
• Cross-Functional Collaboration & Influence: Act as a connector between your team and others - partnering with Product, Design, Security, Identity, and adjacent engineering teams to deliver cohesive auth experiences, anticipating cross-system dependencies, resolving ambiguity, and driving alignment on technical approaches. Participate actively in planning, retrospectives, and cross-team discussions - bringing your perspective to help shape the team's roadmap.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• 6+ years of professional software development experience with a strong emphasis on full-stack web engineering.
• Proficiency with AI-assisted development tooling (e.g., Claude Code, Cursor) demonstrated by at least one year of daily use, in addition to a commitment to an AI-first engineering culture that leverages these tools to maximize code quality, test coverage, and engineering velocity.
• Proficiency in a modern server-side web framework (e.g., Ruby on Rails, Django, Laravel), with hands-on experience building and operating production web applications at scale, including ownership of their reliability and on-call support.

Preferred Qualifications

• Demonstrated ability to take loosely defined problems and independently drive medium-to-large features from definition to production with minimal oversight, making sound technical tradeoffs along the way.
• Strong communication and collaboration skills, with a track record of working effectively across Product, Design, and Engineering - and of mentoring engineers and raising the technical bar of a team.
• Experience with authentication and identity standards such as OAuth2, OpenID Connect, SAML, or FIDO2/WebAuthn.
• Experience building or contributing to fraud detection, real-time risk engines, or abuse mitigation systems.
• Familiarity with security best practices for credential handling - password storage, session management, token issuance, and rate limiting.
• Experience with React or other modern frontend frameworks for building user experiences.
• Comfort working in a fast-moving product environment with iterative releases and A/B testing.
• Familiarity with CI/CD pipelines, automated testing frameworks, and performance profiling tools.
• Startup or high-growth company experience with a strong bias toward execution and ownership.
