Implement mobile security controls meeting EU classified information handling and disconnected operations requirements
Design mobile platforms capable of operating in zero-connectivity environments with multi-level security constraints
Ensure operational compliance with GDPR Article 32, NIS2 Directive, and EU mobile security certification frameworks
Develop mobile interface documentation suitable for supervisory authority security review and cryptographic validation proceedings
Mandatory Technical Excellence
Expert-level React Native with native module development for iOS/Android security integration
Hardware-backed keystore implementation, secure enclave utilization, and biometric authentication integration
Local database encryption, secure data synchronization, and conflict resolution in disconnected environments
Certificate pinning, mutual TLS, and OAuth 2.0/OpenID Connect implementation in mobile contexts
App shielding, root/jailbreak detection, and runtime application self-protection (RASP) deployment
Exceptional Candidate Requirements
Beyond baseline qualifications, successful candidates will demonstrate at least one of the following:
Design and deployment of mobile applications handling EU CLASSIFIED or NATO RESTRICTED information
Development of mobile security frameworks with formal security verification and penetration testing certification
Contributions to open-source mobile security projects with demonstrated enterprise or government adoption
Participation in EU-funded secure mobile research initiatives (Horizon Europe, Digital Europe Programme, ENISA mobile security frameworks)
Documented vulnerability research in mobile platform security with coordinated disclosure and remediation
Advanced Security Focus Areas
Continuous device attestation and dynamic policy enforcement based on security posture
Secure multi-user data separation with cryptographic boundary enforcement
Anti-forensic design preventing data extraction from lost or compromised devices
Mobile cryptography migration strategies for quantum-resistant algorithms
End-to-end encrypted messaging with perfect forward secrecy and deniability
Mobile Security Architecture Standards
Trusted Execution Environment (TEE) and Secure Element integration for key storage
SafetyNet Attestation API and DeviceCheck implementation for device integrity verification
Control flow obfuscation, string encryption, and anti-tampering mechanisms
Timing attack resistance and power analysis mitigation in cryptographic operations
Dependency verification and binary reproducibility for mobile application builds
Linguistic Proficiency Standards
CEFR C1+ English capability for technical documentation and stakeholder communication
CEFR C1+ working proficiency in German, Russian, Chinese, or Spanish
Ability to produce specifications meeting government and regulatory review standards
Security Assessment Protocol
Comprehensive background verification including employment history validation
Enhanced screening procedures for access to sensitive technical information
EU citizenship or permanent residency required for sensitive infrastructure access
