I/CD & Release Management

•        Configure and maintain mobile CI/CD pipelines (Jenkins, Nexus, Fastlane) including build, test, and deployment stages

•        Knowledge on the full mobile release lifecycle: code signing, provisioning profiles, store submissions (App Store / Google Play), and OTA updates

Security & Performance

•        Apply mobile security best practices: certificate pinning, secure storage (Keychain/Keystore), code obfuscation

Your Profile

Education & Experience

•        Degree in Computer Science or equivalent practical experience

•        Minimum 5 years of professional experience in mobile or web development, with significant exposure to hybrid mobile frameworks

•        Delivering production mobile applications

•        Exposure to mobile security auditing or penetration testing

•        Implement and maintain accessibility standards (WCAG) across mobile interfaces

Soft Skills & Mindset

•        Analytical and rigorous: you approach complex problems methodically and deliver well-reasoned solutions

•        Team player: you collaborate effectively, value collective decisions, and build on existing architectural choices rather than systematically challenging them

•        Pragmatic: you balance technical excellence with delivery constraints and know when "good enough" is the right call

•        Proactive communicator: you document your work, share knowledge spontaneously, and flag blockers early

•        Curious and engaged: you stay current with the fast-evolving mobile ecosystem (OS releases, framework updates, deprecations)
