Join us as a Senior iOS Developer and bring Hardware to life!

We’re on the lookout for an experienced Senior iOS Developer who’s passionate about turning hardware capabilities into seamless, high-performance mobile experiences.

In this role, you’ll design and build robust native iOS solutions that go beyond the basics — integrating camera functionality, NFC communication, and advanced image processing - crafting experiences that are as smart as they are secure.

At QOOBISS we don’t just build apps — we build experiences that connect the digital and physical worlds. If you love exploring what’s possible with iOS hardware and you’re driven by clean, secure, and elegant code, this is where you belong.

Key Responsibilities:

• Design and develop native iOS applications with deep hardware integration (camera, NFC, sensors);
• Implement advanced camera features and image processing pipelines for document scanning, OCR, and computer vision tasks; 
• Develop and maintain iOS SDKs for integration into third-party applications; 
• Implement NFC reading and writing capabilities for contactless communication; 
• Build security mechanisms to detect jailbreak, root access, and other tampering attempts; 
• Work with CoreML, Vision framework, and image analysis algorithms; 
• Ensure high code quality, performance optimization, and memory management; 
• Collaborate with cross-functional teams to define and implement technical solutions; 
• Document SDK APIs and provide technical guidance to integration partners.

 Required Skills & Experience:

• 5+ years of professional iOS development experience; 
• Expert knowledge of Swift and Objective-C; 
• Strong experience with AVFoundation and camera API (capture sessions, video processing, photo capture);
• Proven experience with NFC (Core NFC framework, NDEF, tag reading/writing); 
• Hands-on experience with image processing and computer vision (Vision framework, CoreML, OpenCV); 
• Experience building and delivering SDKs or frameworks for iOS; 
• Strong understanding of iOS security mechanisms and jailbreak detection techniques; 
• Knowledge of Keychain, data encryption, and secure storage practices; 
• Experience with Core Image, Metal, or other image processing frameworks; 
• Understanding of memory management, multithreading, and performance optimization; 
• Familiarity with CI/CD pipelines and automated testing;

Nice to Have 

• Experience with document scanning and OCR technologies; 
• Knowledge of biometric authentication (Face ID, Touch ID); 
• Experience with ARKit or other advanced iOS frameworks ;
• Contributions to open-source projects; 
• Experience with mobile payment solutions or fintech applications; 
• Knowledge of certificate pinning and anti-tampering techniques.

What We Offer 

• Challenging technical projects with cutting-edge technologies; 
• Opportunity to work on security-critical applications;
• Collaborative and innovative team environment; 
• Professional development and learning opportunities; 
• Flexible working arrangements. 

We’re building technology that connects people, devices, and ideas in smarter ways — and we’re looking for someone who’s ready to make an impact.

If you’re excited by innovation, love tackling complex technical challenges, and want your work to truly matter, we’d love to hear from you.
