App Developer

The development team at Zenzero deliver and support bespoke systems for a wide variety of end customers and users.

We’re looking for talented Mobile App Developers to join our growing organisation and help us build high‑quality mobile applications for B2B and B2C users. You’ll be part of a collaborative environment that values creativity, modern engineering practices, and continuous improvement. Our organisation is committed to delivering innovative products for our clients and you’ll play a key role in shaping the mobile experiences that support our mission.

In this role, you’ll design, develop, and maintain mobile applications for iOS and/or Android, working closely with product owners and backend engineers. You’ll write clean, maintainable code, integrate with REST APIs, contribute to code reviews, and help troubleshoot issues across the mobile stack. While your primary focus will be mobile development, experience with .NET or .NET Core is a strong advantage, enabling you to support backend services when required.

We’re looking for someone with proven mobile development experience, strong knowledge of modern frameworks, and a solid understanding of mobile UI/UX principles. Familiarity with cloud platforms, CI/CD pipelines, or automated testing is a bonus. In return, we offer a competitive salary and opportunities for professional development. If you’re passionate about building great mobile experiences and want to make an impact, we’d love to hear from you.
