What you’ll do:

• Own the end-to-end mobile and web experience for the Digital Key platform. That covers the full flow from NFC tap and BLE connection to lock unlock, enrollment, and audit, across the React Native mini app, the native SDKs, and the admin web portal.
• Lead technical design and architecture for our React Native SDKs and mini apps. This includes things like moving to React Native’s New Architecture (TurboModules, bridgeless mode) and setting clear module boundaries in a large Expo monorepo.

• Architect hardware integrations by partnering with lock vendors on BLE/NFC SDK contracts and firmware updates, so that unlocks stay reliable across many device types, operating system versions, and store environments.
• Partner with product, design, backend, and host-app teams on API contracts, feature flags, store-by-store rollout plans, and incident response.
• Drive scale and performance work, such as faster BLE connections and higher unlock success rates, offline key caching, app startup time, bundle size, and the effect of permissions and manifest changes on how many devices can install the app.
• Improve how the team operates through mobile observability (telemetry and funnel events, alerting, dashboards), phased releases, runbooks, change management, and healthy on-call.
• Lead platform work on the frontend and mobile side: reusable component libraries, shared SDK tooling, CI/CD pipelines, and better developer experience across the monorepo.
• Mentor engineers, lead design reviews, and shape the long-term mobile and web roadmap with engineering leadership.
