JOIN OUR TEAM

iOS Developer

Join the team behind one of the world’s leading caller ID apps. 

At CallApp, we’re building a product millions of people use every day. Our app helps users identify unknown callers, block spam, and manage their communication with confidence. 

Our iOS app is less than two years old, built from day one in modern SwiftUI. There’s no legacy UIKit to maintain: just a clean, modern codebase with plenty of room to shape how it evolves. 

What you’ll do 

Own features end to end: plan, build, test, and release core app modules and extensions (Call Directory, CallKit, Widgets, Live Activities). 

Write clean, maintainable Swift and keep PRs focused and reviewable. Propose patterns, modularize components, and weigh trade-offs with the team before decisions are locked in. 

Use AI tools throughout your workflow, from brainstorming and generating test data to speeding up bug hunting and documentation. 

What you bring

Solid professional experience building native iOS applications. 

Deep expertise in Swift, SwiftUI, and the iOS frameworks, with the independence to take on complex features. 

Sharp attention to detail. You catch visual glitches and subtle bugs before they reach QA. 

Strong engineering habits. You write testable code, keep PRs small and commits clear, build thoughtful abstractions, and add automated tests where they pay off. 

A learning mindset and friendly, clear communication. You ask “why,” welcome feedback, and lift the team through pair programming (human or AI) and knowledge sharing. 

Nice to have 

Phone-related APIs such as CallKit, the Contacts framework, or other VoIP tools. 

SwiftData or another storage layer (Core Data, Realm, etc.). 

UI and unit testing. 

CI/CD pipelines and TestFlight distribution. 

Why join now

Learn at scale: build features that reach millions of users, using the latest iOS technologies. 

Mentorship-focused team: work alongside experienced iOS engineers who are invested in helping you grow. 

Financially strong and growing: a profitable company with global reach and real room to advance. 

Competitive benefits: attractive salary, hybrid work (one day from home), a dog-friendly office in the Bursa district next to the light rail, and an on-site gym.
