Senior iOS Engineer - Food Ordering App Rewrite

About the role

Jetpacks!, a digital accelerator helping companies grow, is looking for a Senior iOS Engineer to lead the rewrite of a food ordering mobile app from Ionic into a fully native iOS app in Swift. The role also involves contributing to the Android (Kotlin) version, backend services and POS integrations (Toast). iOS is the top priority, so deep Swift experience is required, along with hands-on Android experience and comfort moving across the stack.

Key responsibilities

• Lead the migration of an existing Ionic mobile app into a native iOS app built with Swift.
• Design and build clean, scalable architecture, reusable components and smooth user experiences for menus, cart, checkout and order tracking.
• Contribute to the native Android app in Kotlin, keeping feature parity across platforms.
• Develop and maintain backend services and APIs supporting the mobile apps.
• Build and maintain integrations with POS and food ordering platforms such as Toast.
• Handle App Store releases, TestFlight builds and production monitoring and bug fixing.
• Work closely with the client team, product and design, sharing estimates, progress and technical recommendations.
• Write well-tested, maintainable code and take part in code reviews.

Required profile

• 5+ years of mobile development experience with strong, hands-on iOS experience in Swift.
• Experience shipping and maintaining native iOS apps in production through the App Store.
• Ability to work autonomously and communicate directly with client stakeholders.
• Advanced English level.

Required skills

• Working knowledge of Android development with Kotlin.
• Full stack experience building and consuming backend services and REST APIs.
• Experience integrating third-party APIs and SDKs (payments, authentication, push notifications).
• Solid understanding of MVVM and Clean Architecture, Git and CI/CD workflows.
• Preferred: experience with Toast POS, migrating hybrid apps to native, e-commerce or ordering flows, and remote agile work for US-based clients.
