Job description

What you’ll do at Thule

As a Mobile App Developer, you will design, develop, and maintain both cross‑platform and native mobile applications, with a primary focus on Android development using Kotlin. You will also contribute to iOS and Flutter development when needed.

You will work closely with product managers, UI/UX designers, and backend engineers to understand requirements, define solutions, and bring new features to life. A key part of your role will be ensuring quality and stability, troubleshooting issues, addressing performance challenges, and resolving security‑related findings as they arise.

Beyond development, you will play an active role in maintaining a strong engineering foundation. This includes writing and executing automated unit and integration tests, keeping technical documentation up to date, and contributing to a smooth and reliable deployment process from internal test builds to App Store releases. You will also participate in peer code reviews, helping to maintain high standards across the codebase and ensuring consistency, readability, and long‑term maintainability.

What you bring

To be successful in the role, you have a degree in Computer Science or a related field and solid experience in mobile application development. You are confident in Android development, ideally with Kotlin, and have exposure to iOS development in Swift. Experience in Bluetooth‑enabled applications is a plus.

You enjoy working in a structured way, take pride in building robust, well‑tested, and maintainable solutions, and are pragmatic and adaptable when priorities shift or new challenges emerge. You are comfortable collaborating in a cross‑functional environment and can communicate clearly in English, both verbally and in writing. Most importantly, you bring a problem‑solving mindset and a genuine interest in building high‑quality mobile experiences.
