Job description

Software Engineer III - Wallet - Authentication

Location: Mountain View, California, United States

Compensation: $168,926 - $204,000 USD / year

Role Overview

ID.me is seeking a Software Engineer III 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 Software Engineer III, you will work end‑to‑end across our authentication stack — building features that balance security, usability, and trust at scale. 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

• Build & Ship Authentication Features: Build, maintain, and improve the ID.me Wallet authentication experience — sign‑in, registration, MFA, account recovery, password reset, and MyWallet. Independently drive small‑to‑medium 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 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, and help raise the bar for authentication reliability, observability, and incident response across the team's services.
• 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 the health of the codebase 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.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
• 3+ 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 at least 2 years of hands‑on experience building and operating production web applications.

Preferred Qualifications

• Demonstrated ability to independently ship well‑tested, production‑quality features with minimal oversight.
• Strong communication and collaboration skills, with a track record of working effectively across Product, Design, and Engineering.
• 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 front‑end 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.
