Mobile Developer

Job description

Job Description:
About the Role
We are seeking an experienced (4-7 Years) and independent Senior Software Engineer to join our Experimentation Platform team as a contractor.

In this role, you will be solely responsible for building, maintaining, and optimizing iOS and Android SDKs that enable experimentation at scale.
This position requires someone who is hands-on, highly technical, and capable of delivering latency-critical solutions, while also being able to debug and resolve production issues independently across both platforms.
Responsibilities

+ Lead the design, development, and maintenance of iOS and Android SDKs for the experimentation platform.

+ Deliver optimized, low-latency, and reliable SDKs for large-scale mobile applications.

+ Independently debug, troubleshoot, and resolve production issues on both iOS and Android SDKs.

+ Own the full lifecycle of SDK development — from architecture, implementation, testing, to release management.

+ Partner with backend and experimentation platform teams to ensure seamless integration and end-to-end functionality.

+ Implement best practices in mobile SDK versioning, automated testing, CI/CD, and performance monitoring.

+ Provide strong documentation and developer support to enable easy SDK adoption.

Qualifications

+ 4+ years of professional software development experience, with deep expertise (minimum of 3 years experience) in both iOS (Swift/Objective-C) and Android (Kotlin/Java).

+ Proven track record of building and maintaining production-grade SDKs/libraries.

+ Strong understanding of low-latency mobile networking, concurrency, and memory management.

+ Experience independently debugging complex production issues across diverse devices and OS versions.

+ Familiarity with mobile performance profiling, crash analysis, and monitoring tools.

+ Ability to work with minimal guidance and drive solutions end-to-end.

+ Excellent communication skills and ability to collaborate across teams.

What the Team is Looking For
A self-starter and hands-on engineer who can own both iOS and Android SDK development with minimal supervision.

You should excel at writing optimized solutions in latency-sensitive environments, while also being able to quickly diagnose and resolve production issues.

This is a critical role to accelerate experimentation and innovation across our platform.
Skills

+ SDKs (iOS & Android)

+ Java,

+ Kotlin

+ React Native

+ Data Structures
