Role Overview ID.me is seeking a Staff Software Engineer, Full Stack to join the Commerce & Loyalty team, which owns the ID.me Shop experience — cashback, affiliate offers, merchant discounts, and loyalty programs — along with the marketing and campaign surfaces that drive member engagement and commerce revenue. This position will work from our Mountain View, CA office five days per week. This role is full stack: you will spend significant time on the React/Next.js web experience across Shop and SuperApp, while also building and extending the backend services and APIs that power these features. You will be the technical anchor for the team's frontend surfaces, driving architecture decisions, raising the engineering bar, and partnering closely with Design and Product to translate commerce, personalization, and loyalty concepts into working member experiences. This is a product-focused role: your primary charter is deepening and scaling the Shop product experience itself, rather than owning shared platform or design-system infrastructure. Where patterns built for Shop are broadly useful, you may contribute reusable components back to ID.me's shared UI Foundations on an as-needed basis. Key Responsibilities Build and Maintain Shop Web Experiences: Own and evolve the Shop front-end surfaces using React, Next.js, and TypeScript, including personalized offer discovery, cashback/loyalty flows, and merchant/store pages. Build and Extend Backend Services: Build and extend backend REST endpoints and services to support new or modified frontend features, taking full ownership from UI through backend rather than handing work to another team.

Support Infrastructure Modernization: Participate in ongoing platform work such as the GKE migration for Shop and adoption of shared UI patterns across the Shop codebase. Contribute to UI Foundations as Needed: When a component or pattern built for Shop has broader applicability, contribute it back to ID.me's shared design system so other product teams can adopt it — without this becoming a primary focu
