Job Description

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 Alpharetta 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 3 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.
