Senior Software Engineer (Wallet, Authentication)

• 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
• 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
