Senior Mobile App Developer (iOS/Android)

Stockholm

We’re the experience innovation company – a trusted partner to the world’s most recognized brands. To our people, we offer growth opportunities, a values‑driven culture, international careers and the chance to shape the future of experience.

The opportunity

Valtech is looking for a Senior Mobile App Developer with 6+ years of experience who is confident developing native mobile applications for both iOS and Android.

This role is for someone who takes mobile development seriously—not just individual platforms, but the craft of building high‑quality mobile products as a whole. You care deeply about performance, architecture, and long‑term maintainability, and you have strong opinions on how mobile apps should be built, backed by hands‑on experience across platforms. You are comfortable using AI‑powered tools responsibly to support development, improve code quality, and increase efficiency across the mobile development life‑cycle.

We are looking for a senior app developer who drives work proactively, collaborates closely with clients, product, and design teams, and confidently owns technical decisions across both iOS and Android.

We are first and foremost looking for a senior native app developer. In addition, we highly value T‑shaped profiles who bring depth in app development combined with strength or interest in adjacent areas.

Role responsibilities

• Development of native applications (no React Native)
• Primary focus on iOS, with solid understanding and experience in Android
• Drive app development, technical decisions, and new ideas
• Act in a proactive, advisory role towards the client
• Represent Valtech in the day‑to‑day collaboration
• Close collaboration within a senior, cross‑functional team

Must have qualifications

• iOS
  • Swift
  • SwiftUI, UIKit
  • CocoaPods, Swift Package Manager (SPM)
  • Xcode
  • MVVM
  • The Composable Architecture (TCA)
• Kotlin, Java
• Jetpack Compose
• Fluent in Swedish and English

Nice to have qualifications

• Git
• Fastlane
• Firebase & Crashlytics
• REST / Networking (e.g. Alamofire)
• Database management (GRDB, Core Data)
• Authentication & security (MSAL, Auth0)
• Third‑party integrations (Google ML Kit, Adyen, Contentful, Usercentrics)
• Unit testing & UI testing
• Publishing and management via App Store Connect & Google Play Console
• Beta testing (TestFlight, Apple Business Manager, Google Play Testing Tracks)
• You have a solid understanding of UX/UI design for mobile apps and can work according to each platform’s design principles when developing new features:
  • iOS: Cupertino / Liquid Glass
  • Android: Material Design

If you do not meet all the listed qualifications or have gaps in your experience, we still encourage you to apply. At Valtech, we recognize that talent comes in many forms, and we value diverse perspectives and a willingness to learn.

The benefits

This is a full‑time position based in Stockholm, Sweden with a hybrid working model (at least 2‑3 days work from our Stockholm office).

Beyond a competitive compensation package, we offer:

• Flexibility, with remote and hybrid work options (country‑dependent)
• Career advancement, with international mobility and professional development programs
• Learning and development, with access to cutting‑edge tools, training and industry experts

Our benefits are tailored to each location. Your Talent Partner will provide full details during the hiring process.
