[Hiring] Senior Mobile Software Engineer @Xperteez Technology

Role Description

In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input.

• Create Reinforcement Learning Environments that test an AI model’s ability to solve complex mobile software engineering problems related to:
• Fixing code
• Creating features
• Refactoring code
• Optimizing performance
• Tasked with creating a reproducible environment and a golden reference solution for each problem.

Qualifications

• Kotlin
• Swift
• Mobile

Requirements
