Volledige vacaturetekst

We are looking for a Senior Hybrid Mobile Developer to join our product engineering team at MAINSYS. You will play a key role in designing, building, and maintaining our mobile banking applications built on Ionic, Angular, and Capacitor.

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

Core Technical Skills

JavaScript / TypeScript (advanced)
Angular 18+ and RxJS
Ionic 8+ and Cordova / Capacitor 7+
REST API integration
Node.js ecosystem and NPM package management
HTML5 / CSS3 (SCSS)
Testing frameworks (Playwright)
Git version control and branching strategies

Tooling

IDEs: IntelliJ / WebStorm, VS Code, Xcode, Android Studio
CI/CD: Jenkins, Nexus, Fastlane
Project tracking: Jira

Nice to Have

Knowledge of Java / Kotlin (Android) and/or Swift (iOS) for native plugin development or debugging
Familiarity with AI-assisted development tools (e.g. Claude Code)
Experience publishing and maintaining internal or public NPM libraries
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

Our offer

Work on a challenging project inside a young and dynamic team
A competitive salary combined with extra-legal benefits, including a mobility budget with the option to choose between a company car and/or reimbursement for sustainable transport, and even, under certain conditions, reimbursement of your mortgage or rent.
Access to our training platform
Enjoy access to the Benefits@Work platform and its exclusive offers.
Homeworking facilities (3 days/week)
Homeworking full-time during three weeks in a row or separately (including from abroad).

A Macbook will also be provided for your work.

If you are this person, come and join us!
