[Remote] Architect

Note: The job is a remote job and is open to candidates in USA. UnitedHealth Group is a health care innovation company developing solutions in data analytics, artificial intelligence, cybersecurity, and other complex health care domains. The Senior Mobile Architect will own the technical direction of a large-scale Expo and React Native member application, establish architectural standards, resolve complex production issues, and guide distributed engineering teams. The role is hands-on and includes code reviews, release readiness, micro-frontend architecture, integrations, mentoring, and collaboration with backend, security, and product teams.

Responsibilities

• Own architectural decisions across state management, navigation, API integration, caching and degraded-network behavior, cross-platform (iOS/Android/web) rendering, and native and micro-frontend module boundaries
• Evaluate and document trade-offs for significant technical changes; establish patterns the broader team follows
• Define and maintain the technical standards and quality bar for a platform operating at 1M+ user scale
• Review pull requests and provide substantive architectural feedback, not surface-level approval
• Serve as the escalation point for complex technical questions from onshore and offshore engineers
• Mentor mid-level and junior developers; grow the team's capacity to make sound decisions independently
• Lead diagnosis and resolution of complex production issues, including performance regressions, crash clusters, and platform-version incidents
• Own release readiness for the mobile application: upgrade strategy, dependency currency, native build and release pipelines (Bitrise), app-store submission, and rollback posture
• Provide senior technical coverage during U.S. Central-time afternoon hours, when offshore team members are offline
• Lead the mobile architecture for major integration initiatives, including current strategic program work
• Own the micro-frontend boundaries: evolve the shared feature module consumed by other host applications, and integrate third-party federated widgets across module lines (shared authentication/session, navigation bridges, and independent versioning)
• Partner with backend, security, and product teams on API contracts (including consumer-driven contract testing), authentication flows, and data-handling requirements
• Translate the behavior and constraints of the existing codebase for stakeholders who need to plan against it

Skills

• 8+ years of professional software engineering experience
• 5+ years building and shipping production React Native applications
• 5+ years experience as the senior technical authority on a mobile application at scale (hundreds of thousands of active users or more)
• 3+ years architecture experience in the mobile space
• Experience with AI/ML-enabled platforms, rules engines, and audit systems
• Background in Payment Integrity / Claims processing
• Track record of leading large-scale transformations / platform consolidation

Benefits

• Flexibility to work remotely from anywhere within the U.S.
• A comprehensive benefits package
• Incentive and recognition programs
• Equity stock purchase
• 401k contribution
