We are in need of an Android Developer to join our team to solve real-time cyber challenges. Looking for individuals who enjoy working on a mission-focused team that works very closely with our end users.
Duties include:
Design custom software tools and techniques for the Android platform.
Be responsible for end-to-end design and development of custom software.
Diagnose and debug issues using both COTS and GOTS tools.

Network sockets programming and expert packet-level understanding of IP, TCP, and application-level protocols.
Tracing code execution in a debugger (WinDbg/gdb/IDA Pro).
Reverse engineering native binaries.
Developing proof-of-concept exploit software.
Knowledge of Unix kernel internals, including the OS runtime linker/loader, object file formats (e.g., ELF), file system internals (e.g., NTFS, ext2, btrfs), OS-specific mandatory and discretionary access control mechanisms, and process and thread APIs and data structures.
Understanding of security protection mechanisms (ASLR, DEP, NX), how to defeat them, and how to detect a defeat.
Working with version control software such as git, Gitlab, etc.
Desired Skills (Optional):
Experience with native-level mobile development.
Experience with vulnerability analysis.
Experience with assembly, preferably ARM.
Understanding of mobile security protection mechanisms, such as SELinux and application sandboxing.
