We're looking for someone with a passion for creating robust, well-tested, and elegantly documented code. You will work in a highly collaborative environment with our Android, backend, web, and product teams to build and deliver software used by millions of end users around the world.
What You'll Do- Design, develop, and maintain critical mobile components in both Swift and Objective-C.
- Go beyond surface-level development to explore the depths of the iOS platform, including low-level APIs, performance optimization, memory management, and background processing.
- Build and maintain a robust testing suite (unit, integration, and E2E) and fully automate our build, testing, and release processes using CI/CD pipelines.
- Investigate and solve unique and challenging technical problems that require deep research and first-principles thinking.
- Act as the subject matter expert for all things iOS, providing technical guidance and helping to shape our long-term mobile strategy.
- Work closely with Android, web, backend, and product teams to ensure seamless integration of your iOS components with many other aspects of Signifyd’s technology stack.
- Create and maintain clear, comprehensive technical documentation for your iOS products.
- Collaborate with our Android team to ensure consistency and architectural alignment across platforms.
- Extensive professional experience in native iOS development with strong proficiency in both Swift and Objective-C.
- Demonstrable experience building foundational, reusable mobile components, libraries, or frameworks.
- A strong understanding of API design principles and a passion for creating clean, maintainable, and robust code.
- Deep knowledge of mobile testing methodologies and frameworks (e.g., XCTest, XCUITest).
- Hands-on experience implementing and managing CI/CD pipelines for mobile development (e.g., GitHub Actions, Jenkins, Fastlane).
- Exceptional problem-solving skills, a curious mindset, and meticulous attention to detail.
- Excellent communication and documentation skills, with the ability to collaborate effectively in a cross-functional team environment.
