Description:

Location:

4500 Bohannon Drive Menlo Park CA USA 94025

Hybrid

• We re hiring (more than one) senior iOS Developer for our Client’s 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, Swift

UI, 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, Swift

UI, or lesser-known frameworks like Authentication Services or Web Kit

• 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.
