Senior Mobile Developers (iOS & Android) – Enterprise-Grade Secure Communication

Job description
Location: Remote (US/Canada/Europe/Brazil)

Summary:

We are hiring senior mobile developers (iOS and Android) to build and maintain secure mobile applications powering secure communications, real-time mobile threat detection, and enterprise-grade compliance enforcement. This role focuses on delivering robust, policy-enforced apps with encrypted messaging, voice/video communications, mobile DLP controls, and Intune/MDM posture enforcement in multi-tenant SaaS environments used by both corporate enterprises and government agencies.

Key Responsibilities:

✅ Secure Mobile Communications Development
• Develop native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) apps delivering encrypted messaging, secure voice/video calling, file sharing with encryption, and PSTN bridging with dedicated numbers.
• Ensure real-time synchronization, offline-first messaging, and adaptive session controls (muting, ejection, dynamic channel policies).

✅ Mobile Threat Defense Integration
• Integrate real-time mobile threat detection SDKs including on-device AI posture detection, motion alerts, malicious app detection, and network anomaly monitoring.
• Implement DNA-based authentication, emergency SOS triggers, and device-level risk scoring influencing live session participation.

✅ Intune/MDM and Identity Enforcement
• Lead Microsoft Intune integration with application-level MDM policies, including compliance posture validation, policy-triggered access enforcement, and remote lock/wipe flows.
• Implement full OIDC/SAML-based enterprise SSO flows, per-tenant identity mapping, adaptive RBAC, and conditional access flows based on device posture and user roles.

✅ DLP Controls and Compliance Features
• Enforce mobile DLP controls including screen capture prevention, file sharing restrictions, clipboard sanitization, and dynamic policy enforcement based on organizational rules.
• Develop multi-tenant audit logging, per-tenant compliance exports, and real-time security telemetry forwarding to SIEM and compliance reporting pipelines.

✅ Multi-Tenant and Compliance-First Architecture
• Build and maintain apps for multi-tenant environments, supporting per-tenant branding, per-tenant policies, and role-based access segmentation within the apps.
• Ensure alignment with ISO27001:2026, SOC2 Type II, CMMC 2.0, and FedRAMP Moderate/High compliance guidelines across app functionality and telemetry.

✅ Cross-Team Collaboration & Agile Delivery
• Collaborate with backend, DevOps, and product teams on end-to-end feature design, telemetry handling, backend integration, and CI/CD pipeline automation.
• Work closely with UI/UX designers to transform Figma designs into highly responsive, secure mobile experiences.

Required Qualifications:
• 10+ years experience building and delivering secure mobile applications across iOS and Android.
• Demonstrable expertise with Swift/SwiftUI (iOS) and Kotlin/Jetpack Compose (Android) in regulated, high-security environments.
• Expert-level integration with Intune/MDM, OIDC/SAML SSO, conditional access policies, and RBAC-driven session control.
• Proven experience embedding mobile threat detection SDKs or on-device posture scoring mechanisms.
• Mastery in building compliance-ready mobile apps, including DLP enforcement, audit logging, and real-time SIEM telemetry support.
• Hands-on experience with GitOps CI/CD pipelines, automated security testing, and containerized build environments (Bitrise, GitHub Actions).
• Strong understanding of high-compliance deployments, App Store/Google Play, private distribution (ABM/ZTE), and enterprise in-house app management.

Preferred Experience:
• Previous involvement with air-gapped mobile deployments or government-specific app distribution portals.
• Experience in real-time security telemetry flows connecting mobile applications to enterprise SOC environments.
• Familiarity with offline-first compliance policies and field-deployed secure communication use cases.
