iOS Developer - Fintech

On behalf of our client we are looking for an experienced iOS Consultant to lead the development of a brand-new native iOS SDK – a greenfield project with big technical impact.

Today, we offer a Web SDK. Now, we're moving into native territory and need to build a robust iOS SDK from the ground up. This SDK will interact with backend and frontend components, using a Backend-for-Frontend (BFF) approach to dynamically fetch and display content, rather than handling heavy logic internally.

Your role:

• Design and build a scalable, clean iOS SDK using Swift
• Develop a lightweight interface that communicates with our BFF service
• Collaborate with backend engineers and frontend stakeholders
• Ensure strong performance, modularity, and testability from day one
  
  

You bring:

• 5+ years of iOS development experience
• Strong skills in Swift and native SDK architecture
• Experience building SDKs or libraries for third-party consumption
• Comfort working with API-driven, dynamic UI rendering
• A proactive, solutions-oriented mindset
  
  

Details:

• 🗓 6-month contract
• 📍 1 day per week onsite in Stockholm
• 🕐 Start date flexible – now or after the summer
