Position Description

We’re hiring (more than one) senior iOS Developer in Calgary for our ETRADE and Wealth Management App team a collaborative group of folks that value craftsmanship and curiosity. This position is on-site in our Calgary office (minimum of days a week).

We’re not looking for someone who just knows how to build screens.

We’re looking for an engineer who understands why things work the way they do — someone who can reason about performance, architecture, and the nuances of Apple’s frameworks like a true craftsman.

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
• 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

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.

This is a full-time position and is expected to be at least one year in duration. The candidate must work on-site, a minimum of days a week. Vacation policy is flexible with advance notice.

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.
