Job Title: IOS Engineer (Remote)

Remote Working | Engineering Team | Full-time

The Impact you will create on the Job:

Developing SDKs on IOS with support for cross-platform technologies like ReactNative, Flutter along with hybrid development over platforms like Cordova.

Apply data structures and algorithms to optimize the code for a lower memory, battery, and processing footprint - all with the goal to build plug-and-play SDKs that don’t expect the app developers to write any supporting code in the app.

You will be liaising with the cross-functional teams to get an in-depth understanding of the functional requirements and propose scalable solutions.

As an individual contributor, you will tackle some of our broadest technical challenges that requires deep technical knowledge, hands-on software development and seamless collaboration with all functions.

You will envision and develop features that are highly reliable and fault tolerant to deliver a superior customer experience.

You will get an opportunity to work with some of the best talent while learning from various highly-functional teams in the company.

You will collaborate with your team and set an example by delivering high quality and innovative engineering solutions for complex use cases.

Plan and execute the roadmap with the engineering team to build and deliver next-generation systems.
