About the role

Key responsibilities & impact

Own the mobile architecture blueprint—from client app layers to backend integration (APIs, microservices, event-driven patterns)
Define standards and reference architectures for React Native/Flutter/Xamarin (or hybrid web-views, Capacitor) and native interoperability
Establish mobile domain models, API contracts, security controls, and data governance for mobile
Create roadmaps aligned with business OKRs, balancing innovation with platform stability
Lead architecture for new mobile initiatives: authentication flows, offline-first patterns, background sync, push notifications, deep linking, app configuration, and feature flagging
Design scalable backend integrations (API gateways, GraphQL/REST, caching, pub/sub), and select runtime patterns (BFF, façade services)
Architect telemetry pipelines for observability (crash analytics, performance metrics, RUM, log aggregation)
Implement Zero Trust principles for mobile; enforce secure storage, device attestation, jailbreak/root detection
Align with OWASP MASVS/MSTG, NIST, ISO 27001; ensure compliance (GDPR, CCPA, HIPAA/PCI as applicable)
Oversee MDM/UEM and MAM policies (e.g., Microsoft Intune, VMware Workspace ONE, MobileIron)
Define threat models, conduct architecture risk assessments, and drive secure SDLC practices (SAST/DAST, dependency scanning)
Define CI/CD pipelines for mobile (Fastlane, Bitrise, Azure DevOps, GitHub Actions, CircleCI), code signing, release orchestration
Standardize testing strategy: unit/UI/e2e, device farms, accessibility, performance, and compatibility testing
Govern app distribution (App Store/Play, Enterprise distribution), versioning, rollback strategies, and release trains
Architect for offline resilience, concurrency, graceful degradation, and efficient network usage
Establish SLAs/SLOs/SLIs for mobile experiences; implement synthetic monitoring, crash thresholds, and performance budgets
Optimize startup time, memory footprint, battery usage, and bundle size
Model data flows; select client-side storage (Secure Enclave/Keychain, Keystore, SQLite/Room/Realm, encrypted stores)
Define API schemas and backward compatibility strategies; manage schema evolution and versioning
Champion API governance and service cataloging; integrate with identity (Azure AD/Entra ID, Auth0, Okta)
Maintain architecture repository and guardrails, including coding standards, dependency policies, and modularization
Run Architecture Review Boards, perform ADRs (Architecture Decision Records), and maintain tech radar
Mentor architects and senior engineers; conduct design reviews and coaching
Partner with Product, UX, Security, Infra/Cloud, and Business stakeholders; translate business goals into technical plans
Vendor management: Evaluate frameworks, SDKs, third party services; negotiate and manage technical risk
