iOS Developer

Are you an iOS Developer with a few years of experience and a drive to grow your skills in both UIKit and SwiftUI? Do you enjoy building well-crafted native apps using modern Apple technologies? At Triple, we’re looking for a Mid-level iOS Developer to strengthen our team!

What will you be doing?

As a medior iOS Developer at Triple, you’ll work on designing and developing native iOS applications for a variety of clients. You’ll collaborate closely with your team, applying solid coding practices and learning more about scalable architectures as you go.

Depending on the project, you might work with UIKit, SwiftUI, or a combination of both. Some projects involve newer codebases, while others may include legacy components—so some familiarity with Objective-C can come in handy, though it’s not a must.

Your responsibilities include:

• Developing new features and improving existing ones

• Fixing bugs and troubleshooting issues

• Contributing to app performance and stability

• Collaborating with your team and stakeholders to shape new functionalities

• Following architectural guidelines and helping maintain code quality

• Writing unit tests and participating in code reviews

• Learning from senior team members and gradually taking more ownership

The team

You’ll be part of a development department with over 70 developers, including a dedicated iOS team of 7. We work in cross-functional scrum teams alongside designers, front-end and back-end developers, QA engineers, and project managers.

We value learning and sharing knowledge—every week, we run an internal iOS Weekly, where we explore new tech, discuss solutions, and exchange ideas. You’ll also get opportunities to attend conferences like NSSpain and take part in fun team events, whether it’s laser tag or a friendly sports match.

What do you bring with you?

• HBO-level (Bachelor’s) working and thinking skills

• Around 3 years of hands-on experience with native iOS development

• Solid skills in both UIKit and SwiftUI

• Understanding of architecture patterns such as MVVM, VIPER, or Clean Architecture

• Objective-C experience is a plus, but not required

• Good communication skills in English (Dutch is a bonus)
