This role is for a senior mobile engineer on the Residential platform. While the title is mobile-focused, the engineer in this role must also be comfortable working across cloud-backed APIs, authentication flows, and app-to-service integration boundaries. The team needs someone who can build polished mobile experiences and also reason effectively about the backend systems that support them.

We are seeking a Senior Engineer, Mobile Applications to help design, build, and improve customer-facing and field-facing mobile capabilities across the Residential platform.

This is a hands-on senior individual contributor role. The engineer in this position will be expected to own meaningful technical decisions, contribute directly to implementation, mentor less-experienced engineers, and help raise engineering standards across both mobile delivery and mobile-to-cloud integration work.

• →Design, build, and maintain mobile features across Residential mobile applications on iOS and Android.
• →Lead technical delivery for complex React Native and TypeScript-based mobile work in a shared-codebase environment.
• →Build and support integrations with REST APIs, GraphQL services, authentication systems, and backend-for-frontend or gateway layers.
• →Contribute to backend-facing work when needed, including API contract design, auth/session behavior, payload handling, and service-integration troubleshooting.
• →Improve app stability, performance, responsiveness, and release quality across iOS and Android.
• →Help define mobile architecture, state management, secure local storage, sync behavior, and maintainable component patterns.
• →Troubleshoot production issues that cross mobile, API, authentication, and cloud-service boundaries.
• →Contribute to CI/CD, release-readiness, app-store delivery, and secure engineering practices.
• →Partner with cloud engineering, product, UX, QA, and support teams to deliver high-quality end-to-end solutions.
• →Mentor junior engineers and contribute to code reviews, technical design discussions, and engineering best practices.

• Bachelor’s degree in Computer Science, Engineering, or a Hard Science (Physical, Life, or Applied Science).
• 7+ years of software engineering experience.
• 4+ years building and shipping production mobile applications across both iOS and Android.
• 3+ years of hands-on experience with React Native and TypeScript.
• 2+ years integrating mobile applications with REST APIs, GraphQL APIs, or comparable service-based backends.
• 2+ years working with authentication, authorization, token lifecycle management, and secure session handling in production applications.
• 2+ years building, supporting, or troubleshooting backend or cloud services in AWS or a comparable cloud environment.
• 3+ years debugging issues across app, API, and cloud-service boundaries.
• 2+ years working with modern CI/CD, code review, testing, and release workflows for mobile delivery.
• Ability to collaborate effectively during U.S. Eastern Time business hours.

• Experience with connected-home, IoT, smart device, or subscription-based consumer applications.
• Experience with backend technologies such as Node.js and TypeScript for API or service-layer development.
• Experience with API gateways, backend-for-frontend patterns, or identity-provider integrations.
• Experience with secure local storage patterns such as Keychain, MMKV, SecureStore, AsyncStorage, or comparable approaches.
• Experience with state-management and data-fetching patterns such as Redux Toolkit, RTK Query, or similar approaches.
• Experience with mobile observability, crash analysis, and production diagnostics using tools such as Crashlytics, LogRocket, or similar platforms.
• Experience with native integrations such as BLE, biometrics, camera or QR flows, OEM SDKs, or React Native native modules.
• Familiarity with AWS-backed platforms, cloud debugging, and backend operational concepts.
• Experience using AI-assisted development tools such as Cursor, Claude, Kiro, or similar tools to accelerate coding, debugging, testing, and delivery.

• Role Type: Individual Contributor
• Level: Senior Engineer
• Primary Assignment: Residential mobile applications, based on business need
• Work Model: Remote within the United States
• Collaboration Expectation: Regular overlap with U.S. Eastern Time business hours
