• Experience building and maintaining an open-source project or design library is a plus.


Qualifications:-

• 2+ years of experience writing, maintaining and releasing iOS apps at scale
• Strong mobile ecosystem fundamentals with expertise in iOS SDK framework and Swift. 
• Experience with local databases, offline storage, threading, and performance tuning
• Familiarity with RESTful APIs to connect iOS applications to back-end services
• Familiarity with the use of additional sensors, such as cameras, gyroscopes and accelerometers
• Ability to understand business requirements and translate them into technical requirements
• Ability to learn quickly and adapt to new technologies and development practices is a plus
