Nice to Have

• Experience with iOS reversing (Objective-C / Swift, Mach-O)
• Knowledge of anti-debugging / anti-tampering techniques
• Experience with emulators, virtualization, or sandboxing
• Cryptography and protocol analysis experience
• Exploit development or vulnerability research background

What We Expect

• Ability to work with incomplete information and figure things out independently
• Strong debugging mindset and curiosity
• Focus on real-world results, not just theoretical analysis
• Clean and well-documented findings

About the Role

We’re looking for an experienced AOSP Engineer to work on deep Android system-level modifications and customizations.

We’ve built a product-focused GovTech platform that removes the gap between virtual and physical phones, and this role is critical in pushing Android beyond standard device behavior.

You will work directly with AOSP internals, modifying core system components, services, and hardware abstractions to achieve production-grade behavior under non-standard environments.

Responsibilities

• Customize and extend AOSP for specific product requirements
• Modify and debug Android system services (framework + native layers)
• Work with HALs, Binder IPC, and low-level system components
• Implement and adjust behavior related to:
  • Device identity & system properties
  • Networking, telephony, sensors, and system state
  • Power, battery, and lifecycle behavior
• Integrate and adapt Android builds for virtualized / emulated environments
• Debug complex issues across Java/Kotlin and native C++ layers
• Analyze system logs, traces, and crashes (logcat, tombstones, systrace, etc.)
• Collaborate with reverse engineers and backend teams on system behavior

Requirements

Core Skills

• Strong experience with AOSP (building, modifying, debugging)
• Solid knowledge of:
  • Android architecture (Framework, System Services, HAL)
  • Binder IPC and Android service model

  • System properties and device configuration
• Ability to debug across layers (kernel ↔ HAL ↔ framework)

Tools

• adb, fastboot, logcat, systrace
• Debugging tools (gdb/lldb, ndk-stack)
• Build system (Soong / Make)

Who This Is For

This role is for engineers who:

• Enjoy working below the app layer
• Are comfortable breaking and rebuilding Android internals
• Prefer solving real system problems over building UI

• Experience supporting complex technical products or SaaS platforms with integrations.
• Ability to manage multiple brands, priorities, and cross-functional teams simultaneously without losing focus.

• Ability to quickly immerse yourself in client business context, platform capabilities, and operational processes.

• You are a business partner, not a ticket administrator.
• You become a trusted point of contact during difficult situations, whether involving delays, incidents, or challenging decisions.
• You maintain complete awareness of the status and priorities across your portfolio.
• You build trust between clients and delivery teams, ensuring productive collaboration rather than friction.
• You are eager to help scale the function by sharing knowledge, refining standards, and contributing to team growth.

How We Measure Success

• Brands in your portfolio experience predictable, transparent communication with no surprises around ETAs or status updates.
• Every request has a clear owner, status, and action plan; nothing gets lost.
• Customer Health is actively managed, with risks identified and addressed before escalation.
• Feature Adoption continuously grows, with clients actively utilizing the platform capabilities they invest in.
• Recurring customer pain points become structured inputs for product improvements.
• The standards and methodologies you create are adopted across the Customer Success function and become part of how every new CSM operates.

It’s cool to work with us

• Flexible schedule: work from home, the office, or hybrid;
• Extra day off for your birthday: take a break any day within the month;
• Competitive compensation that matches your skills;
