About The Opportunity

We are looking for Mobile Engineers to join our Compliance engineering team. In this role, you will build secure, regulation-compliant, and high-trust mobile solutions that power global onboarding, identity verification, risk control, and regulatory compliance systems.

We are open to candidates across a wide spectrum of experience. Whether you are an engineer early in your career eager to master mobile security and regulatory technology, or a seasoned practitioner who can architect resilient systems and drive technical direction across global markets, you will find high impact and technical depth here. You should be self-driven, hungry to grow, and motivated by solving critical real-world engineering challenges.

What You'll Be Doing

  • Build, maintain, and scale native iOS features and user flows using Swift and modern iOS frameworks.
  • Collaborate with Product, Design, and Backend Engineering to translate functional requirements into smooth, responsive mobile experiences.
  • Integrate third-party SDKs, native frameworks, and hardware capabilities (such as camera APIs, biometrics, or local security features) with a focus on UX and performance.
  • Contribute to mobile client architecture, keeping the codebase modular, testable, and maintainable.
  • Participate in code reviews, testing, and continuous optimization to maintain high iOS engineering standards.
  • Leverage modern development tools and AI coding assistants to streamline your daily workflow and accelerate delivery.
  • Diagnose and fix edge cases, performance bottlenecks, and production bugs to ensure a rock-solid iOS app experience.

What We Look For In You

  • Hands-on native iOS engineering experience with Swift, SwiftUI, and UIKit.
  • Solid grasp of software engineering principles, memory management, multithreading, and mobile system design.
  • Experience integrating RESTful APIs into production iOS applications.
  • Commitment to writing clean, well-tested, and maintainable code.
  • Strong problem-solving mindset with a desire to build high-quality software.
  • Openness to using modern developer tools and AI coding assistants (e.g., Claude Code, Codex) in your everyday coding workflow.

Nice-To-Haves

  • Exposure to mobile CI/CD pipelines (e.g., Fastlane, GitHub Actions, Xcode Cloud).
  • Experience working with modular iOS architectures or building internal shared SDKs/frameworks.
  • Familiarity with unit testing frameworks (XCTest) and UI testing on iOS.
  • Experience with feature flagging, analytics, or A/B experimentation frameworks.
