Staff software engineer - iOS

Qualifications

• - 8 or more years of software engineering experience, with 6+ years building and shipping production iOS applications in Swift, including Objective-C interop in large legacy codebases
• - You take pride in creating iOS magic and love exploring mobile device capabilities, the latest advancements in the Swift language, and are curious to know what is happening in the iOS world
• - Deep expertise in iOS frameworks and app architecture — SwiftUI and UIKit, Swift Concurrency (async/await, actors), Combine, and the tradeoffs between MVVM, VIPER and unidirectional patterns at scale
• - Proven track record architecting modular iOS codebases — feature modularization, dependency injection, and versioned internal frameworks that let many engineers ship in parallel without stepping on each other
• - Hands-on experience with on-device machine learning and intelligence on Apple platforms — Core ML, Vision, Natural Language, and the Foundation Models framework for on-device LLM inference
• - Practical understanding of the tradeoffs between on-device and server-side inference: latency, cost, offline capability, model size, and the privacy advantages of keeping sensitive financial data on device
• - Fluency with AI-assisted development — using coding agents and LLM tooling (Claude Code, Copilot, Cursor) to accelerate delivery, with sound judgment about where generated code needs careful review, especially in security- and compliance-sensitive paths
• - Expertise with the iOS delivery toolchain: Xcode build systems, Swift Package Manager/CocoaPods, Fastlane, and CI/CD pipelines with automated release trains and phased App Store rollouts
• - Strong command of mobile quality and performance engineering — XCTest/XCUITest, snapshot testing, Instruments profiling, crash triage, app size, cold-start latency, and battery/network efficiency
• - Experience owning app security and compliance concerns on device: secure storage of sensitive financial data, Keychain, biometric authentication, and secure API/token handling
• - Deep customer empathy and ability to quickly translate insights into mockups, wireframes, and working proof-of-concept code
• - Expertise in quickly translating design (Figma/Zeplin) into working iOS code, with a high bar for accessibility, internationalization and instrumentation
• - Ability to mock out server side dependencies to move fast, plus solid knowledge of server side development processes, tools and technology — including partnering on API and contract design
• - Strong bias to action — bring ideas to life quickly through prototyping, experimentation and a JFDI attitude. Basically someone who can get stuff done
• - Solid communication skills: demonstrated ability to explain complex technical issues to both technical and non-technical audiences, and to build alignment across teams without formal authority
• - Demonstrated ability to mentor and grow engineers, raise the bar in code and design reviews, and act as a technical role model
• - BS/MS in computer science or equivalent work experience
