Position Description:

We’re hiring (more than one) senior iOS Developer for our E*TRADE and Morgan Stanley Wealth Management App team-a collaborative group of folks that value craftsmanship and curiosity. This position is on-site in our Menlo office (minimum of 3 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 Local Authentication to Common Crypto -- 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 Menlo 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.
