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
 

We’re looking for a highly technical and strategic partner to help us build a mobile identity framework that enables the creation and use of clean, unlinked, and high-trust mobile accounts at scale — primarily using real devices.
 

This project is currently operated manually, and we’re intentionally keeping the path flexible: we’re seeking someone who can analyze the current approach, evaluate trade-offs, and help us determine whether it should stay manual, move to semi-automation, or become more automated — depending on what best serves long-term stealth and trust-building goals.
 

Responsibilities:
 

• Design and configure real-device mobile environments (Android/iOS) for creating and managing independent, unlinkable user identities;

• Analyze and mitigate tracking vectors used by apps/platforms — including:

  * Device fingerprinting;

  * Behavioral pattern detection;

  * Account linkage via shared data;

  * Sensor, network, and OS-level signals;

• Provide guidance — and any necessary support — across all layers required to achieve full stealth and trust-building (e.g. proxies, SIM handling, app behavior management);
• Help define and maintain operational workflows that ensure ongoing account hygiene and identity separation;
• Collaborate on evaluating and deciding between manual, semi-automated, or automated implementations.
   

Ideal Skill Set:
 

• Deep understanding of mobile tracking and fingerprinting (Android essential; iOS a plus);
• Familiarity with device identifiers: Android ID, IMEI, SSAID, MAC, and how apps link user data;
• Hands-on experience with tools like Frida, Magisk, Xposed, or similar for app analysis or behavioural control;
• Experience working with real Android/iOS devices — including SIM management, proxy routing, and device/network hygiene;
• Strong grasp of trust models and anti-fraud systems — how platforms score accounts over time;
• Ability to simulate organic user behavior and shape usage patterns to avoid detection;
• Comfortable guiding decisions on manual vs. automated approaches based on operational goals.
   

Bonus: 
 

• Experience with custom ROMs, MicroG, or sandboxed app environments.

Key Responsibilities:

• Analyze APK files and decompile code
• Research native code (C/C++ via JNI)
• Identify and bypass protection mechanisms
• Perform dynamic analysis and runtime code modification
• Discover vulnerabilities and conduct security testing
• Develop custom reverse engineering tools

Requirements:

• 2+ years of experience in reverse engineering
• Strong knowledge of C/C++, Smali, Java, Assembler
• Proficiency with tools: IDA Pro, Ghidra, Binary Ninja, JADX, etc.
• Solid understanding of Android architecture and OS internals
• Knowledge of network protocols
• Analytical mindset and attention to detail
