Senior iOS App Developer

Software Guidance & Assistance, Inc., (SGA), is searching for a Senior iOS App Developer for a CONTRACT assignment with one of our premier Financial Services clients in Menlo Park, CA.

The goal of this department is to develop Client-facing Websites and Mobile Applications. Working as a member of this team, the candidate will be responsible for developing and supporting external client facing web and mobile applications in an open and collaborative environment. This position is on-site in our Menlo office (minimum of 3 days a week).

If you are an exceptional individual who is interested in working at the frontier of digital finance, this is the place for you.

Responsibilities:

• 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
  
  

Required Skills:

• BA/BS in Computer Science or related field, or equivalent practical experience.
• 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
• Strong written and verbal communication skills in English.
  
  

Preferred Skills:

• Experience developing APIs
• Awareness of Android app development.
• Strong user experience skills.
