Senior Ios Developer

Role Overview

We're looking for an Senior iOS Developer to help build and scale our native iOS POS application from the ground up. You'll work on payment-critical features Tap to Pay, secure authentication, real-time transaction handling - in a fast-moving, high-ownership environment.

Key Responsibilities

• Build and maintain native iOS applications using Swift and SwiftUI
• Implement Tap to Pay on iPhone using NMI's ChipDNA SDK (or similar payment SDKs)
• Build secure authentication flows including passkeys
• Integrate REST APIs and handle real-time webhook-driven data
• Work closely with backend (Node.js/NestJS) and web teams to ship end-to-end features
• Write clean, testable, maintainable Swift code and participate in code reviews
• Debug and optimize app performance, memory usage, and reliability
• Collaborate directly with founders/leads on architecture decisions we lock designs upfront before writing code

Required Skills

• Strong hands-on experience with Swift and SwiftUI
• Solid understanding of iOS app architecture (MVVM or similar), Xcode, and the App Store submission process
• Experience consuming REST APIs and handling async data
• Understanding of iOS security fundamentals (Keychain, biometrics, secure storage)
• Ability to work independently and communicate clearly on technical tradeoffs

Good to Have

• Experience with payment SDKs (Tap to Pay, Stripe Terminal, or similar)
• Experience with WebAuthn/passkey implementations
• Exposure to UIKit (for legacy/interop work)
• Familiarity with push notifications, background tasks, and offline-first app design
• Hands-on use of Claude Code, Cursor, or other AI coding tools in real projects
• Prior experience in fintech, payments, or POS systems

AI-Native Development

We build with AI tools as a core part of our workflow, not an afterthought. You'll be expected to work fluently with Claude Code, Cursor, and prompt-driven workflows for scaffolding, debugging, and code review using AI to accelerate execution, not replace design thinking.

What We Offer

• Direct ownership of a native iOS product from early stage
• Fast-paced, execution-focused team (no bureaucracy)
• Opportunity to work on payment-critical, high-security mobile features
• MacBook provided for work
• Competitive salary based on experience
