What You ll Do

• Architect and build robust, scalable iOS applications using Swift and SwiftUI
• Write clean, testable, maintainable code with a strong emphasis on performance and reliability
• Dive deep into Apple APIs from LocalAuthentication to CommonCrypto and use them to solve real-world problems elegantly

• Mentor other developers and help shape the technical culture of our Calgary office
• Use AI tools to accelerate development not replace it freeing up time for deeper thinking and more impactful work

What We re Looking For

• Collaborative mindset: You re thoughtful, curious, and easy to work with we try to keep it not so fussy
• AI maturity: You use AI tools to enhance your workflow not to substitute for foundational knowledge

How We Interview

In our phone screen, you ll walk us through three examples from your own code:

• Swift Language: We re looking for depth concurrency, generics, protocol design not just syntax
• Apple APIs & Frameworks: Show us how you ve used UIKit, SwiftUI, or lesser-known frameworks like AuthenticationServices or WebKit
• Apple Ecosystem: Talk about your experience with CI/CD, Xcode, performance tuning, app signing, crash analysis, or architecture decisions

We re not looking for perfection we re looking for engineers who think deeply, communicate clearly, and care about the craft of iOS development.
