ID.me is a full-time, in-office culture. Unless a specific job description explicitly states otherwise, all roles are on-site five days per week at one of our offices in McLean, VA; Mountain View, CA; New York City, NY; or Tampa, FL. Certain roles — such as field-based sales or other remote-by-design positions — may have different work arrangements as noted in their individual postings.

At ID.me, we embrace the thoughtful use of AI tools in our daily work and there are even occasions where we leverage AI in our hiring process. However, during the interview process, we want to understand your individual skills and experiences. Therefore, we have guidelines on how AI can be appropriately used during your application and interviews which can be found here.

Role Overview

ID.me is seeking a Senior Software Engineer to join the Wallet/Authentication Platform 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 work end-to-end across our authentication stack — designing and shipping features that balance security, usability, and trust at scale. You bring strong product instincts and technical depth, operating with a high degree of independence while partnering closely with Product, Design, and Security. Your work sits 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

• Build & Ship Authentication Features: Design, build, maintain, and improve the ID.me Wallet authentication experience — sign-in, registration, MFA, account recovery, password reset, and MyWallet. Independently drive medium-to-large features end-to-end from design through deployment, collaborating closely with Product, Design, and Security to translate requirements into well-tested, production-ready code.
• Security, Risk & Reliability: Own and evolve real-time risk and abuse detection 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, and help raise the bar for authentication reliability, observability, and incident response.
• Code Quality & Engineering Craft: Write high-quality, maintainable code with strong test coverage, following team best practices around code reviews, CI/CD, and documentation. Contribute to codebase health by identifying and addressing technical debt and improving 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: Partner with Product, Design, Security, Identity, and adjacent engineering teams to deliver cohesive auth experiences. Participate actively in planning, retrospectives, and cross-team discussions — bringing your perspective to help shape the team's roadmap.
• Mentorship & Leadership: Provide technical guidance to junior engineers through code reviews, design discussions, and pairing. Help establish and reinforce team standards and best practices.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• 5+ years of professional software development experience with a strong emphasis on full-stack web engineering.
• 1+ years of experience 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.
• 3+ years of experience in Java and Spring Boot, with at least 3 years of hands-on experience building and operating production web services.

Preferred Qualifications

• Strong communication and collaboration skills, with a track record of working effectively across Product, Design, and Engineering.
• Demonstrated ability to independently own and ship complex features end-to-end with minimal oversight.
• Experience with authentication and identity standards such as OAuth 2.0, OpenID Connect (OIDC), SAML, or FIDO2/WebAuthn — hands-on implementation experience is a strong plus.
• Experience with or exposure to Identity Provider (IdP) or Identity and Access Management (IAM) systems and how they integrate with relying parties.
• Familiarity with security best practices for credential handling — password storage, session management, token issuance, and rate limiting.
• Experience building or contributing to fraud detection, real-time risk engines, or abuse mitigation systems.
• Experience with React or other modern frontend frameworks for building authentication 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.
