Key Responsibilities

Development & Architecture

• Design, develop, and maintain hybrid mobile applications using Ionic 8+, Angular 18+, and Capacitor 7+

• Integrate complex authentication flows from third-party providers (OAuth 2.0, OpenID Connect, biometric SDKs) in a mobile context

• Integrate and manage third-party SDKs (payment, push notifications, analytics, security) while ensuring stability and performance

• Implement offline-first patterns, secure local storage, and efficient data synchronization

• Ensure cross-platform consistency across iOS, Android, and multiple device form factors

• Write and maintain comprehensive unit tests and contribute to end-to-end testing strategies

Technical Leadership & Analysis

• Conduct detailed technical analyses on complex topics and produce clear documentation to guide other developers in their implementation work

• Mentor junior and mid-level developers through knowledge-sharing sessions

• Act as a technical reference for the team on mobile-specific challenges

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

• French-speaking (working language); English proficiency is a strong asset

• Understanding of deep linking, universal links, and push notification architectures (FCM / APNs)

• 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)

• Mentoring mindset: you find satisfaction in helping others grow and in elevating the overall quality of the team’s output
