The Sr. Software Engineer (Mobile) designs, develops, and maintains the mobile version of VEXIS — Vizy Pay's proprietary CRM platform. This is a ground-floor (0?1) product mandate: the role owns mobile architecture and delivery end-to-end, from the technology approach recommendation through distribution in the Apple App Store and Google Play Store. As a hands-on individual contributor with technical mentorship responsibilities, the role establishes Vizy Pay's mobile engineering standards.

Operating in a security- and compliance-driven payments environment, the role is accountable for a secure, performant, and reliably released mobile experience in production.

• Own the architecture, security, and performance of VEXIS mobile across iOS and Android; lead the native vs. cross-platform evaluation and own the recommendation, weighing cost, performance, maintainability, and alignment with Vizy Pay's existing Type Script/Angular engineering stack.
• Define and enforce mobile engineering standards — project structure, state management, offline-first data, testing, and accessibility — and mentor engineers through code reviews, pairing, and design reviews as a hands-on individual contributor.
• Work within an Agile software development environment, collaborating closely with Product, Engineering, UX/UI, and other stakeholders throughout the software development lifecycle using Agile methodologies and best practices; align the mobile roadmap with platform architecture, security controls, and product roadmaps in partnership with Information Technology (Infrastructure & Security, Software Engineering).
• Design, develop, and maintain the VEXIS mobile application: API integration with backend services (REST, Web Sockets), push notifications (APNs/FCM), offline-first synchronization, and a responsive, performant user experience.
• Build and operate mobile CI/CD and release management (e.g., Azure Dev Ops, Git Hub Actions, fastlane): automated builds, code signing, and store submission workflows through App Store Connect and Google Play Console, with staged rollouts and release-health monitoring.
• Implement automated testing across the mobile stack (e.g., XCTest, Espresso, Detox, Appium, Maestro) with quality gates; monitor crash and performance data (e.g., Firebase Crashlytics, Sentry) to drive root cause resolution.

• Engineer the application secure-by-design, aligned with PCI DSS and OWASP MASVS/MASTG: secure storage (Keychain/Keystore), certificate pinning, secure token and session handling, and least-privilege API access.
• Partner with Infra Sec on mobile threat modeling, logging, monitoring, and audit readiness; operate all production releases under formal change management with audit-ready change records.

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent experience required.
• Required 5+ years of professional software engineering experience with a strong mobile emphasis, including 3+ years shipping and operating production mobile applications distributed through the Apple App Store and Google Play Store, with accountability for quality, performance, and outcomes.
• Certifications:
  
  Google Associate Android Developer (AAD), App Development with Swift Associate, App Development with Swift Certified User, or equivalent certifications, preferred.
• Experience in security- or compliance-constrained environments (e.g., PCI DSS, SOC 2, or financial services regulation), delivering under formal SDLC and change management within Agile development environments.
• Proven ability to…
