Communication Swift CI/CD Android

Job Specifications

• 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

• Optimize performance using profiling tools, concurrency strategies, and thoughtful design

• 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

• Strong CS fundamentals: You understand memory management, data structures, algorithms, and concurrency — and you know when to apply them

• Deep iOS expertise: You’ve built and shipped complex apps, and you know the ins and outs of UIKit, SwiftUI, and the broader Apple ecosystem

• Architectural thinking: You can design modular, testable systems and have opinions about MVC, MVVM, and beyond

• Curiosity and craftsmanship: You care about how things are built, not just what gets built

• Ecosystem fluency: You’ve worked with CI/CD, app signing, provisioning, Instruments, and understand the full lifecycle of an iOS app

• Clear communicator: You can walk through your own code and explain your decisions. You’re comfortable saying “I don’t know” and having a relaxed, technical conversation

• 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

Additional Required Skills:

• Strong written and verbal communication skills in English.

• BA/BS in Computer Science or related field, or equivalent practical experience.

Additional Desired Skills

• Experience developing APIs.

• Awareness of Android app development.

• Strong user experience skills
