We’re building advanced simulation infrastructure that mirrors how mobile environments behave — across Android and iOS — at scale.

This means designing environments that act like trusted users. With real signals. Real sensors. Real networks. And real control.

You’ll own the systems behind it.
The goal: simulate at depth, control the stack, and remove noise — all while remaining adaptable to what’s changing underneath.

🧠 What You'll Build

• Mobile environments that mimic real user behavior
  
   
• Fully controlled Android stacks (custom ROMs, rooted, virtualized, multi-instance)
  
   
• Environment variance systems: fingerprints, entropy layers, behavior profiles
  
   
• Simulation flows that reproduce sensor, network, and gesture realism
  
   
• Run hypothesis tests on setups to identify what breaks trust and what holds
  
   

Tooling to manage environments, rotate identity profiles, and log output signals
